Fabric Manager FICON 5.2 Quickstart
Introduction
IBM® Fibre Connections (FICON®) is an industry-standard, high-speed input/output (I/O)
interface for mainframe connections to storage devices. For a range of storage area network
(SAN) devices that support FICON, refer to:

Fabric Manager 5.2
In this section, we show you differences that were introduced in Fabric Manager (FM) 5.2. We
assume that you have upgraded all of the switches in your fabrics to Fabric Operating System
5.2 and that you have installed Fabric Manager 5.2.
In Figure 1, we show the layout of the Fabric Manager 5.2 client. There are major differences
between the 5.1 and 5.2 layouts. Several of the major differences in the layout are:
򐂰 The 5.1 client has a single panel (Content pane) that displays information in either
graphical or tabular form.
򐂰 The 5.2 client has two panels that display information: the View panel displays the
topology and the Information panel displays tabular information. You can view both the
topology and the tabular information at the same time.
򐂰 The 5.1 client has a fabric tree from which you can select fabric elements to monitor and
manage.
򐂰 The 5.2 client does not have a fabric tree; you can select fabric elements from the View
panel or the Information panel.

The major difference in the menus is that with Fabric Manager 5.2, you now access most
tasks through the menu bar Tasks drop-down instead of the Configuration or Tools menu.
You can also access many of these tasks by right-clicking the switch or the fabric when it is
displayed in the View panel.
Figure 2 on page 3 shows the tasks available from the drop-down Context menu.
Tip: Double-clicking the SAN cloud opens that fabric and display the switches in the fabric.

Figure 2 Tasks
In FM 5.2, the View panel always displays a graphical topology view. The Information panel
displays tabular views. In 5.2, you can view graphical and tabular information at the same
time.
The View panel allows you to display three types of SAN views. You select the type of SAN
view that you want in the Scope panel from the View drop-down menu:
򐂰 SAN View displays all of the monitored fabrics in the database. This is the default view
when you launch the Fabric Manager client.
򐂰 Fabric View displays the switches and their interconnectivity for a single fabric.
򐂰 Host-Storage View displays the end-to-end connectivity of all of the monitored fabrics.
Figure 3 shows selecting the SAN view.
Figure 3 Selecting SAN view
You can select fabric elements in FM 5.2 from either the View panel or the Information panel.
From the Scope panel displayed in Figure 4 on page 4, we have chosen to display the SAN
View and to display by IP.

From the View panel, we right-clicked on the switch to show the options that are available to
us.
Figure 4 Selecting a fabric element
In the topics that follow, we will point out the steps that we took and highlight any areas that
we think you might overlook if you are familiar with Fabric Manager 5.1 and below.
Our initial configuration is for a fabric called IP70. In our first examples, we focus on the
switch, M48256. We log in to Fabric Manager to display the fabric, IP70, and the other switches
that constitute this fabric. In the Scope panel, we request a SAN View and to display the
fabric by name. We show this in Figure 5.
Figure 5 SAN view
We double-click the fabric IP70 cloud icon to select that fabric and show the switches that it
includes. Figure 6 on page 5 shows the switches in IP70.

Notice that now the Scope panel has changed to reflect the Fabric view.
Launching switch admin
Because we want to work with the director named M48256, we select the Admin functions for
that director by right-clicking M48256 in the View panel, and then clicking Admin from the
Context menu as shown in Figure 7 on page 6.
Note: We select switches and use their context menus many times throughout this IBM
Redpaper. We suggest that you familiarize yourself with this process.

After we right-click M48256 in the View panel, and click Admin from the Context menu, you will
recognize the Admin windows if you are familiar with FM 5.1.
We show the tabs in Figure 8 on page 7.

FICON
IBM automatically supports native FICON on Fabric OS 5.0.1 and above for the IBM
TotalStorage® SAN256B director and the IBM TotalStorage SAN32B fabric switch.
To incorporate and manage FICON on a switch or a fabric, you must have Fabric OS v4.1.2
or higher installed on your system (Fabric OS 5.0.1b or later for the SAN32B and SAN256B).
In addition, your system must have Fabric OS 4.4 or higher installed (Fabric OS 5.0.1b or
later for the SAN32B and SAN256B) in order to incorporate and manage the new FICON
CUP feature on a switch.
The SAN64B-2 (2005-B64) and the SAN18B-R (2005-R18) are supported from Fabric OS
v5.2.0b or above.
The following models and Fabric OS releases support FICON protocol:
򐂰 Model 2109-F32 Fabric OS v4.1.2 or later.
򐂰 Model 2109-M12, Fabric OS v4.1.2 or later. The dual domain configuration is supported;
however, mixed FC-16 and FC2-16 port blade configurations are not supported.
򐂰 Model 2109-M14, Fabric OS v4.2.0 or later. The default one domain configuration is
supported; however, dual domain configurations and mixed FC-16 and FC4-16 port blade
configurations are not supported.
򐂰 Model 2005-B32, Fabric OS v5.0.1b or later.
򐂰 Model 2109-M48, Fabric OS v5.0.1b or later. A single domain configuration is supported
with a mix of 16-port and 32-port blades (FC3416 and FC3432).
򐂰 Feature code (FC) 3450 or FC3450 in a 2109-M48, Fabric OS 5.2.0b or later is supported.
򐂰 FC3448 can exist in a FICON environment; however, FICON device connection to ports
on these blades is not supported.

򐂰 Model 2005-R18, Fabric OS 5.2.0b or later, but you must maintain the two hop FICONs.
򐂰 Model 2005-B64, Fabric OS 5.2.0b or later.
Intermixed FICON and Fibre Channel Protocol
FICON intermix allows you to run both FICON and Fibre Channel Protocol (FCP) through a
shared director-class IBM TotalStorage SAN switch.
FICON and Control Unit Port support
There are two types of supported FICON configurations:
򐂰 A single-switch configuration, which is called switched point-to-point, requires that the
channel is configured to use single-byte addressing. If you set the channel up for two-byte
addressing, then the cascaded configuration setup applies.
򐂰 A cascaded configuration, which is also known as a high integrity fabric, requires a list of
authorized switches. This authorization feature, which is called fabric binding, is available
through Brocade Secure Fabric OS or the Access Control List (ACL) mechanisms. The
fabric binding policy allows a predefined list of switches (domains) to exist in the fabric and
prevents other switches from joining the fabric.
FICON support of cascaded directors means that a native FICON (FC) channel or a FICON
channel-to-channel (CTC) can connect a server to a device or other server using two
same-vendor directors. FICON support of cascaded directors only supports a two-switch,
single-hop configuration.
You can use the FICON Management Server (FMS) to support switch management using
Control Unit Port (CUP). IBM mainframe management programs use the CUP protocol to
provide in-band management for FICON switches. To use this feature, you need to install the
FICON with CUP license.
To be able to use the CUP functionality, all switches in the fabric must have FICON
Management Server mode (FMS mode) enabled. FICON Management Server mode is a per
switch setting. After you enable FICON Management Server mode, you can activate a CUP
license without rebooting the director.
Next, we briefly discuss several of the basic functions available on the FICON CUP tab. For
complete information, refer to the Brocade WebTools Administrator’s Guide, 53-1000049-02.
8
Fabric Manager FICON 5.2 Quickstart
From within the Admin section of WebTools, we use the first tab, FICON Management Server
Mode, under the FICON CUP tab to enable the FICON Management Server mode, as shown
in Figure 9.
Figure 9 FICON Management Server Mode tab of FICON CUP tab
The first subpanel determines the mode of the FICON Management server, which is either
enabled or disabled.
The next subpanel is entitled FICON Management Server Behavior Control and displays
several default settings that have already been defined.
The Code Page subpanel displays the language that is used to exchange information with
Host Programming.
The Control Device Allegiance panel shows that the Control Device Allegiance is in a default
neutral state. When it is neutral, the Control Device accepts commands from any channel,
which has established a logical path with it and will accept commands from alternate
managers. When the Control Device is switched, it establishes a logical path and accepts
commands only from that logical path (device allegiance).

To check whether a switch has FMS mode enabled, you can also discover that from the
Information panel as shown in Figure 10.
Figure 10 FMS mode
When FMS Mode is true, this indicates that FMS mode is enabled; false indicates that it is
disabled.

Fabric Manager FICON 5.2 Quickstart
After we enable the FICON Management Server, we use the CUP Port Connectivity
Configurations tab to configure the ports as shown in Figure 11.
Figure 11 CUP Port Connectivity Configurations tab under FICON tab
The CUP Port Connectivity Configurations tab shown in Figure 11 has a default view, which
displays the CUP configuration list.
The functions on this tab are:
Activate

FICON quickstart
In this topic, we discuss the basic steps to configure a switch for FICON in both a switched
point-to-point and a cascaded configuration.
We will discuss the basic FICON/mainframe steps that you need to perform. It is not our
intent to show any of the steps on the mainframe; however, we highlight the considerations.
Hardware Configuration Definition
An I/O configuration defines the hardware resources available to the operating system and
the connections among these resources. The resources include:
򐂰
򐂰
򐂰
򐂰
Channels
ESCON/FICON Directors (switches)
Control units
Devices
You must define an I/O configuration to the operating system (software) and the channel
subsystem (hardware). The Hardware Configuration Definition (HCD) element of z/OS®
combines hardware and software I/O configuration information under a single interactive user
interface. HCD also performs validation checking, which helps to eliminate errors before you
attempt to use the I/O configuration.
The output of HCD is an I/O definition file (IODF). An IODF is used to define multiple
hardware and software configurations to the z/OS operating system. When you activate an
IODF, HCD defines the I/O configuration to the channel subsystem and/or the operating
system. With the HCD activate function or the MVS™ ACTIVATE operator command, you can
make changes to the current configuration without performing an initial program load (IPL) of
the software or a power-on reset (POR) the hardware. Making changes while the system is
running is known as dynamic configuration or dynamic reconfiguration.
You select your I/O configuration when you:
򐂰 POR
򐂰 IPL
򐂰 Activate a dynamic configuration change
IPL and activation require that you identify the IODF that contains the definition of your
configuration. A data set called an I/O configuration data set (IOCDS) is used at POR. You
can create an IOCDS from a configuration definition in an IODF. The IOCDS contains the
configuration for a specific processor, while the IODF contains configuration data for multiple
processors.
Important: We highly recommend that you complete the FICON configuration for the
switches before you attempt to bring any CHPIDs or Control Units online. You cannot finish
the switch configuration until the HCD configuration is complete.

the HCD definition process before you attempt to code any of the statements shown in
Figure 12.

Configure the routing policy
You only need to configure the routing policy for Condor ASIC-based products. Port-based
path selection is a routing policy in which paths are chosen based on ingress port and
destination only. This also includes user-configured paths.
All switches with FICON devices attached must have port-based routing policy enabled.
Port-based routing is a per switch routing policy. After you enable port-based routing, you can
continue with the rest of the FICON implementation.
To enable or disable port-based routing:
1. Click a switch with FICON devices attached from the View panel.
2. Launch the switch admin module by right-clicking on the switch, and then clicking Admin.
Fabric Manager FICON 5.2 Quickstart
13
3. Click the FICON CUP tab.
4. The FICON CUP tab displays with the FICON Management Server Mode tab page in
front as shown in Figure 13.
5. Check Enable in the Port Based Routing subpanel to enable the port-based routing policy.
Click to remove the check from this box to disable port-based routing.
6. Click Apply to save your changes.
Note: Check the Active=Saved Mode checkbox if you want to save the FICON CUP port
connectivity configuration as an IPL file, in addition to activating the configuration. The next
time the switch reboots, it loads the configuration from this IPL file.
Figure 13 Enable port routing
Enabling port-based routing means that all frames received on an ingress port destined for a
destination domain are guaranteed to exit the switch in the same order in which they were
received.
Disabling Dynamic Load Sharing using the command-line interface
If Dynamic Load Sharing (DLS) is enabled, traffic on existing inter-switch link (ISL) ports
might be affected when one or more new ISLs is added between the same two switches.
Specifically, adding the new ISL might result in dropped frames as routes are adjusted to take
advantage of the bandwidth provided. You can only disable or enable DLS by using the
command-line interface (CLI).
14
Fabric Manager FICON 5.2 Quickstart
Note: Using the Cascaded FICON utility, which we describe in “Configure a fabric for
cascaded FICON setup” on page 34, automatically disables DLS.
By disabling DLS, you ensure that there are no dropped frames. A similar situation occurs
when you take an ISL port offline and then bring it back online. When the ISL port goes
offline, the traffic on that port is rerouted to another ISL with a common destination. When the
ISL port comes back online and DLS is enabled, the rerouting of traffic back to the ISL port
might result in dropped frames. If DLS is not enabled, traffic will not be routed back.
You can see how to disable (or also enable) DLS by using the CLI as shown in Example 1.
Example 1 dlsreset
M48256:admin> dlsshow
DLS is set
M48256:admin> dlsreset
M48256:admin> dlsshow
DLS is not set
M48256:admin>
FICON requires that DLS is not set.
Configuring in-order delivery
The routing software provides an option to guarantee in-order delivery even during fabric
changes. This option is called in-order delivery (IOD). When IOD is set, the routing code
enforces a hold-down period after an old route is deleted, before installing a new route to the
same destination domain. The hold-down period is equal to E_D_TOV.
The order of the delivery of frames is maintained within a switch and determined by the
routing policy in effect. Next, we list the frame delivery behaviors for each routing policy.
Note: In-order delivery is automatically set to on as part of the cascaded FICON utility
process. See “Configure a fabric for cascaded FICON setup” on page 34 for more details.
The frame delivery behaviors are:
򐂰 Port-based routing
All frames, which are received on an ingress port destined for a destination domain, are
guaranteed to exit the switch in the same order in which they were received.
򐂰 Exchange-based routing
All frames, which are received on an ingress port for a given exchange, are guaranteed to
exit the switch in the same order in which they were received. Because different paths are
chosen for different exchanges, this policy does not maintain the order of frames across
exchanges.
If even one switch in the fabric delivers out-of-order exchanges, then exchanges are
delivered to the target out-of-order, regardless of the policy configured on other switches in
the fabric.
Fabric Manager FICON 5.2 Quickstart
15
Port-based routing is required for FICON.
To configure in-order delivery (IOD), click the Routing tab from the Switch Admin tab of the
switch that you are configuring (Figure 14 on page 16).
Figure 14 In-Order Delivery
In-Order Delivery is now set.
Configuring Domain ID and Insistent Domain ID
In a cascaded configuration, each switch must have a unique Domain ID, and the Insistent
Domain ID (IDID) mode must be enabled.
When the Insistent Domain ID (IDID) Mode is enabled, the current domain setting for the
switch is insistent; that is, the same ID is requested during switch reboots, power cycles, CP
failovers, firmware downloads, and fabric reconfiguration.
Note: Insistent Domain ID is set on automatically as part of the cascaded FICON utility
process. See “Configure a fabric for cascaded FICON setup” on page 34 for more details.
If you do not assign the Insistent Domain ID, the channel will fail the query for security
attributes, and the channel will not come online. This parameter is required for use with
FICON only.
The Query Security Attributes (QSA) exchange is used by the host to determine that the
fabric meets the above requirements.
16
Fabric Manager FICON 5.2 Quickstart
Note: A QSA is an extended link service (ELS) that a FICON host will send to determine
fabric integrity. QSA is a snapshot of the fabric at login time; the host will discover changes
in security attributes at the next login.
A QSA is issued when the channel is configured for 2-byte addressing to check whether
the IDID and Fabric binding bits are set. If they are not, QSA returns FALSE and the
channel will not vary online.
To set a unique Domain ID and enable IDID mode, we will complete the following steps.
Note: There are two methods to set the IDID mode and we will show both of them.
Setting unique Domain ID process
The steps are:
1.
2.
3.

Setting Insistent Domain ID Mode (method one)
To set the Insistent Domain ID Mode:
1. Go to the Configure tab and enable Insistent Domain ID Mode by clicking in the
checkbox as shown in Figure 18.
Figure 18 Insistent Domain ID Mode
2. After verifying that the Domain ID is unique, and that Insistent Domain ID Mode is set, we
click Enable under Switch Status. Click Apply. This enables the switch as shown in
Figure 19.
Figure 19 Enable switch

Figure 23.
Figure 23 Enabling the switch
Click Yes on the Confirm Action window to enable the switch. IDID is now set on the switch.
Access Control Lists
With FM 5.2, the security features have been changed to remove the dependence on a public
key infrastructure (PKI) but still deliver selected security policy enforcement mechanisms
without requiring a “Secure Mode.”
22
Fabric Manager FICON 5.2 Quickstart
Access Control List (ACL) support has moved from Secure Fabric OS (SFOS) and does not
require a license key. Therefore, you now have the ability to create a cascaded FICON
without SFOS.
However, there will be limitations in the first release. In the Fabric OS 5.2.0 release, there will
be no support for ACL configuration under each Admin Domain (AD), and none of the policy
configurations will be validated with AD membership. This means that ACL configuration CLIs
will be executable only in AD0 and AD255. Also, the FICON administrator using v5.2.0 does
not need to learn about Admin Domain configurations, because FICON configurations
requiring a high integrity fabric will use the default Admin Domains of AD0 and AD255.
The Fabric OS 5.2.0 ACL mechanisms and SFOS are mutually exclusive. Switches and
directors that upgrade to Fabric OS 5.2.0 can continue to run SFOS if you choose, and the
security license is installed. However, if you want to take advantage of the built-in ACL
mechanisms of Fabric OS 5.2.0 that do not require a license, you must first disable Secure
Mode on SFOS.
Managing Access Control Lists
For switches running Fabric OS v5.2.x and higher, you can create and activate Switch
Connection Control (SCC) and Device Connection Control (DCC) policies in the base Fabric
OS that are functionally equivalent to the SCC and DCC policies supported in Secure Fabric
OS.
In Secure Fabric OS, these polices are fabric-wide. In the base Fabric OS (for Fabric OS
v5.2.x and higher), these polices are switch-based; however, you can distribute these policies
to all switches in the fabric.
To manage the ACL policies, you must meet the following requirements:
򐂰 You can select only one switch at a time.
Note: You can manage ACL on an entire fabric when you use Configure for Cascaded
FICON Mode.
򐂰 The switch must be running Fabric OS v5.2.x or higher.
򐂰 Security must not be enabled on the fabric.
򐂰 Your user account must have either the Admin or Fabric Admin role for ACL management.
Fabric Manager launches WebTools to manage the ACL policies. The following procedure
describes how to launch the WebTools Switch Admin module from Fabric Manager.
To manage ACL policies, we right-click a switch (M48256) and select ACL Management from
the context menu that appears (alternatively, you can select a switch and then click Tasks →
Switch Management → ACL Management from the Menu bar), as shown in Figure 24 on
page 24.
Fabric Manager FICON 5.2 Quickstart

Figure 24 ACL management from the context menu
The Switch Admin module launches with the ACL - Switch Connection Control Policy tab
selected, as shown in Figure 25. We click Edit to go to the ACL Policy Configuration Wizard in
Figure 26. The ACL Policy Configuration Wizard allows you to create or edit SCC and DCC
policies.

Enabling and disabling Secure Mode
You enable and disable Secure Mode on a fabric-wide basis. You can enable and disable
Secure Mode as often as you choose; however, all Secure Fabric OS policies, including the
Fabric Configuration Server (FCS) policy, are deleted each time that you disable Secure
Mode. You must recreate the Secure Fabric policies the next time that you enable Secure
Mode.
With FM 5.2, the process has become simpler with the introduction of wizards to guide you
through the work that previously you had to perform manually.
Enabling Secure Mode
In the process, we show you how to enable Secure Mode for the fabric IP70.
To enable Secure Mode, you must install the following licenses:
򐂰 Secure Fabric OS license (Security license)
Fabric Manager FICON 5.2 Quickstart

򐂰 Advanced Zoning license (Zoning license)
And although it is optional, at some stage you might require or need:
򐂰 FICON CUP license
Figure 31 on page 28 shows the window where we have highlighted and right-clicked on the
fabric IP70 in order to select Enable Secure Mode from the context menu.
Note: We are going to enable Secure Mode on a fabric that is currently in ACL mode. You
can use this process to convert from ACL mode to Secure Mode.

Figure 32 Overview
The switch that we will use has this IP address, 172.16.20.70, so we select this IP address to
use for the Fabric Configuration Server (FCS) switch. Figure 33 shows this selection.

The next option allows us to keep the current passwords or choose new passwords. We elect
to keep the same passwords, so we check the Keep Current Passwords box. Figure 34
shows this action.

At the next window (Figure 35 on page 30), we choose the security level that we want. We
choose to accept Low and make no changes to those policy names that are already checked.

After we have made our choice and clicked Next, we confirm our actions before clicking
Finish. Figure 36 shows this confirmation window.

After we click Finish, a warning window asks us to reconfirm our choice. Figure 37 on
page 31 shows this warning window.
Figure 37 Enabling Secure Mode warning
We click Yes to start the process. After it has completed, we see the message window shown
in Figure 38.

Figure 38 Secure Mode is enabled
To confirm that we have been successful, now we look at the SAN view, and now we can see
that the IP70 cloud in the View panel now has the Secure Mode padlock associated with it.
Figure 39 shows this padlock.
Figure 39 Secure Mode padlock
32
Fabric Manager FICON 5.2 Quickstart
You can use Secure Mode to secure the fabric if the Fabric OS levels are not all at v5.2.0 or
higher.
Disabling Secure Mode
Now that we have enabled Secure Mode, we will disable it on the IP70 fabric so that we can
configure it for cascaded FICON setup using ACL mode and the wizard. The wizard will only
work if Secure Mode is disabled. After you disable Secure Mode, we still need to configure
the fabric for cascaded FICON to fully implement and activate ACL mechanisms and mode.
Important: You need to convert security in the switch while no other support element
activity is occurring, such as taking channel paths online or offline, performing an IPL, or
activating partitions. If a channel path changes state while you are in the middle of
changing security, the channel or channels will go to definition error status as displayed on
the support element.
To recover the channel path, you must take the specified channel path offline or online
after the ACL process has completed.
Converting security does not disrupt current activity (jobs) running on the mainframe.
In Figure 40 on page 33, we right-click IP70 and from the context menu, we select
Security → Disable Secure Mode.
Figure 40 Disable Secure Mode
After we click Disable Secure Mode, we get the warning shown in Figure 41 asking if we want
to disable Secure Mode.
Fabric Manager FICON 5.2 Quickstart
33
Figure 41 Warning
We click Yes and Secure Mode is disabled as shown in Figure 42 on page 34.
Figure 42 Secure Mode disabled
Currently, we do not have any security enabled in our fabric and we need to correct that. At
the same time, we also want to implement ACL mode, and we do this by configuring the fabric
for cascaded FICON.
Configure a fabric for cascaded FICON setup
In this example, we show the process to configure a fabric for cascaded FICON setup. Many
of the steps that you previously performed manually are now performed automatically as part
of the cascaded FICON utility.
The cascaded FICON utility:
򐂰

Turns on the Insistent Domain ID flag (IDID) on all switches.
Enables port-based routing on 4 Gbps platform switches.
Disables Dynamic Load Sharing (DLS) on all switches.
Enables In-Order Delivery (IOD) on all switches.
Sets High Integrity Fabric Configuration (HIFC) on the seed switch:
– Configures a fabric-wide consistency policy to include SCC in strict mode.
Fabric Manager FICON 5.2 Quickstart
– Creates or modifies the SCC policy to limit connectivity to only the switches in the
selected fabric.
򐂰 (Optional) Turns on FICON Management Server (FMS) mode on all switches. If some
switches already have FMS mode enabled, it is re-enabled.
Fabric Manager performs a Role Based Access Control (RBAC) check on all the switches in
the fabric for the operations listed, except for setting HIFC, for which Fabric Manager
performs an RBAC check on the seed switch only. If the RBAC check fails for any operation
on any switch, an error message displays listing the errors for each failed operation.
If you select FMS mode to be enabled on all switches and some of the switches do not have
a CUP license, then after you complete successful configuration, you can access the Port
Connectivity (PDCM) matrix, but the host system cannot communicate with the FICON
Management Server unless you install a CUP license. If you later install a CUP license on
these switches, then you must re-enable FMS mode on these switches.
In Figure 43 on page 35, we select Tasks → Cascaded FICON Setup → Configure a fabric
for cascaded FICON setup.
Figure 43 Cascaded FICON setup
We select our fabric, IP70, for the fabric to configure as shown in Figure 44.
Fabric Manager FICON 5.2 Quickstart
35
Figure 44 Select fabric
We also elect to turn on FMS mode for all switches by checking the box to the left of Turn ON
FMS mode on all switches. Then, the pop-up window tells us which actions will be carried
out.
The actions are:
򐂰 Turn ON Insistent Domain ID (IDID) flag on all switches.
򐂰 Set High Integrity Fabric Configuration (HIFC) on the seed switch. (Set switch connection
control policies on all switches to limit connectivity to only the switches in the selected
fabric):
– Configure fabric-wide consistency policy to include SCC in strict mode.
– Create or modifies SCC policy to limit connectivity to only the switches in the selected
fabric.
򐂰 Enable port-based routing on 4 Gbps platform switches.
򐂰 Disable Dynamic Load Sharing (DLS) on all switches.
򐂰 Enables In-Order Delivery (IOD) on all switches.
򐂰 (Optional) Turn on FICON Management Server (FMS) mode on all switches. If some
switches already have FMS mode enabled, it is re-enabled.
As a consequence of all these actions, an Activate of the SCC policy is carried out and ACL
mode security for the fabric is implemented. Figure 45 confirms that we have been
successful.

Fabric Manager FICON 5.2 Quickstart
Figure 45 Successful configuration
Now that we have successfully configured IP70 for FICON setup, we will show you the
process to merge two fabrics that have both been configured for cascaded FICON setup.
Merge two fabrics for cascaded FICON setup
Fabric Manager provides a wizard that merges two fabrics for cascaded FICON. You must be
a physical fabric administrator on both fabrics that you want to merge.
In the following example, we merge two fabrics: IP70 and BeeJay. These fabrics are shown in
Figure 46 on page 38.
Fabric Manager FICON 5.2 Quickstart
37
Figure 46 Fabrics to merge
Figure 47 shows how we select the utility. Select Tasks → Cascaded FICON Setup →
Merge two fabrics for cascaded FICON setup.
Figure 47 Merge fabrics
Figure 48 on page 39 shows an overview of the process that is about to occur.
Fabric Manager performs the following operations on the selected fabrics:
򐂰 Check the fabrics for any merge issues.
򐂰 Turn on the Insistent Domain ID (IDID) flag on all of the switches in both fabrics.
38
Fabric Manager FICON 5.2 Quickstart
򐂰 Clear Admin Domain, Access Control Lists (ACLs), and Zoning databases, if they exist,
from one of the fabrics (you select which fabric from within the wizard).
򐂰 Configure High Integrity Fabric Configuration (HIFC) on the seed switch of the other fabric:
– Configure fabric-wide consistency policy to include SCC in strict mode.
– Create or modify the SCC policy to limit connectivity to only the switches in both
fabrics.
򐂰 Enable port-based routing on 4 Gbps platform switches.
򐂰 Disable Dynamic Load Sharing (DLS) on all switches.
򐂰 Enable In-Order Delivery (IOD) on all switches.
򐂰 (Optional) Turn on FICON Management Server (FMS) mode on all switches. If some
switches already have FMS mode enabled, it is re-enabled.
򐂰 (Optional) Configure long distance setting on selected ports (requires extended fabric
license).
If you select FMS mode to be enabled on all switches and if some of the switches do not have
a CUP license, then after successful configuration, you can access the Port Connectivity
(PDCM) matrix, but the host system cannot communicate with the FICON Management
Server unless you install a CUP license. If you install a CUP license later on these switches,
then you must re-enable FMS mode on these switches.
Figure 48 Overview
At least two of the discovered fabrics must meet the requirement that all switches must be
running Fabric OS v5.2.0 or higher; otherwise, an informational dialog displays and the
wizard does not launch.
Note: Only fabrics with Secure Mode disabled will be discovered.
You can see the fabrics that we are going to merge in Figure 49 on page 40.
Fabric Manager FICON 5.2 Quickstart

Figure 49 Select fabrics
The rest of the process is self-explanatory and driven by the wizard, so we will only show the
window process flow.
Figure 50 on page 41 allows us to set FMS mode and select the fabrics.
This part of the process will clear the Admin Domain, the Access Control Lists (ACLs), and
the zone databases, if they exist, from one of the fabrics (you select which fabric from within
the wizard).
Note: Clearing the ACL database in a large fabric might take a long time; for example, in a
50 switch fabric, this operation might take from 30 minutes to one hour.
In our case, we have a small fabric (one switch) joining a much larger fabric so we choose to
clear the ACL database on the small fabric.

This completes the merge of our fabrics.
Enabling FICON CUP
Host-based management programs manage switches using CUP protocol by sending
commands to an emulated control device in Fabric OS. A switch that supports CUP can be
controlled by one or more host-based management programs, as well as by WebTools. A
mode register controls the behavior of the switch with respect to CUP and the behavior of
other management interfaces.
You must install the FICON CUP license, enable FICON Management Server (FMS) mode,
and set the configure CUP attributes (FMS parameters) for the FICON director on the switch
to enable CUP management features.
Enabling FMS mode
When you enable FMS mode, Fabric OS prevents local switch commands from interfering
with host-based management commands by initiating serialized access to switch parameters.
If you plan to use more than one switch in the FICON CUP fabric, you must either install
Secure Fabric OS or enable the Fabric OS v5.2.0 ACL mechanism.
To enable FMS mode from the FICON CUP tab, select Enable under FICON Management
Server Mode as shown in Figure 56 on page 45.
44
Fabric Manager FICON 5.2 Quickstart
Figure 56 FMS mode
To verify that FMS mode is set, we select the switch (M48256) and click the Overview tab.
From the resultant display by paging down, we can see that FMS Mode is set for the switch
as shown in Figure 57 on page 46.
Fabric Manager FICON 5.2 Quickstart
45
Figure 57 FMS Mode is true
Enabling FMS parameters
FMS parameters control the behavior of the switch with respect to CUP, as well as the
behavior of other management interfaces, such as the director console and Alternate
Managers. You can configure FMS parameters for a switch only after you enable FMS mode
on the switch. All FMS parameter settings are persistent across switch power cycles. There
are six FMS parameters:
򐂰 Programmed Offline State Control
This parameter controls whether host programming is allowed to set the switch offline.
The parameter is set as enabled by the hardware after system installation and can be
reset by WebTools.
򐂰 Active=Saved Mode
This parameter controls the IPL file update. The IPL file saves port connectivity attributes
and port names. After a switch reboot or power cycle, the switch reads the IPL file and
activates its contents as the default configuration. When Active=Saved Mode is enabled,
activating a configuration saves a copy to the IPL configuration file. All changes made to
the active connectivity attributes or port names by host programming or alternate
46
Fabric Manager FICON 5.2 Quickstart
managers are saved in this IPL file. It keeps the current active configuration persistent
across switch reboots and power cycles. You cannot directly modify the IPL file or save a
file as an IPL file. When you disable this mode, the IPL file is not altered for either new
configuration activation or any changes made on the current active configuration. This
parameter is set as enabled by the hardware after system installation, and you can reset it
using WebTools.
Note: When FMS mode is enabled and the Active=Saved parameter is disabled, you
can enable and disable ports, but the setting is not persistent. When the Active=Saved
parameter is enabled, you can enable and disable ports and the setting is persistent.
򐂰 Alternate Control Prohibited
This parameter determines whether alternate managers are allowed to modify port
connectivity. Enabling this mode prohibits alternate manager control of port connectivity;
otherwise, alternate managers can manage port connectivity. This parameter is set as
enabled by the hardware after system installation, and you can reset it using WebTools.
򐂰 User Alert Mode
This parameter controls director console behavior for alerts. Enabling this mode prompts
the director consoles to display a warning whenever you attempt an action that will change
switch parameters. When you disable this mode, no warning is displayed. In this case, in
which WebTools is the director console, WebTools displays warning messages regardless
of the setting of the parameter, because WebTools always displays warning messages
when you apply a change to a switch that changes parameters. This parameter is always
read-only in WebTools. Each time that the switch is powered on, the parameter is reset to
disabled.
򐂰 Director Clock Alert Mode
This parameter controls behavior for attempts to set the switch timestamp clock through
the director console. When it is enabled, the director console (WebTools, in this case)
displays warning indications when the switch timestamp is changed by a user application.
When it is disabled, you can activate a function to automatically set the timestamp clock.
There is no indication for timestamp clock setting. This parameter is set as disabled by the
hardware after system installation, and you can reset it by using WebTools.
򐂰 Host Control Prohibited
This parameter determines whether host programming allows modifying port connectivity.
Enabling this mode prohibits host programming control of port connectivity; otherwise,
host programming can manage port connectivity. This parameter is set as disabled by the
hardware after system installation, and you can reset it by using WebTools.
You set the FMS parameters on the same window that you use to enable FMS mode as
shown in Figure 58 on page 48.
Fabric Manager FICON 5.2 Quickstart

Figure 58 FMS parameters
Configuring port connectivity
The Port Dynamic Connectivity Mask (PDCM) is a mechanism to define port connectivity
(also referred to as prohibit/allow).
We click the CUP Port Connectivity tab as shown in Figure 59 on page 49.
48
Fabric Manager FICON 5.2 Quickstart
Figure 59 CUP Port Connectivity tab
In the CUP Port Connectivity Configurations panel (shown in Figure 60 on page 50), you can
manage the configuration files and active configuration. The CUP Port Connectivity
Configurations panel lists all CUP configuration files and the active configuration. The active
configuration is listed as “Active Configuration*” and the description in the table is “Current
active configuration on switch.” The other special configuration file is the IPL. Any other files
that display are user-defined configurations and are stored on the switch.
Fabric Manager FICON 5.2 Quickstart

Figure 60 CUP Port Connectivity
Within FM 5.2, Figure 61 shows a second way for you to display CUP Port Connectivity.
Figure 61 Port Address Configuration
50
Fabric Manager FICON 5.2 Quickstart
You can create, activate, copy, or delete saved CUP port connectivity configurations;
however, you can only edit or copy a configuration while it is active.
You can also activate, edit, or copy the IPL configuration. You must enable FMS mode before
you can make any changes to the configurations. Click Refresh to get the latest configuration
file list from the switch.
When creating a new configuration or editing an existing configuration, remember that the
WebTools port name input is restricted to printable ASCII characters. Therefore, when
WebTools displays a port name, if there are characters beyond printable ASCII characters
(which would have been created by the Host Program), those characters display as dots (.).
When initially installed, a switch allows any port to dynamically communicate with any other
port. Two connectivity attributes are defined to restrict this any-to-any capability for external
ports: Block and Prohibit.
Block is a port connectivity attribute that prevents all communication through a port.
Prohibit is the port connectivity attribute that prohibits or allows dynamic communication
between ports when a port is not blocked. Each port has a vector specifying its Prohibit
attribute with respect to each of the other ports in the switch. This attribute is always set
symmetrically in that a pair of ports is either prohibited or allowed to communicate
dynamically.
Figure 62 shows how we select a configuration for editing. We highlight the configuration and
click Edit.
Figure 62 Selecting configuration
The Port Connectivity table (shown in Figure 63 on page 52) displays the Port number (in
physical-location format), Port Name (port address name), Block attribute, Prohibit attribute,
and Area ID (port address, which is displayed in hexadecimal format) in fixed columns. The
right side is a port matrix, which lists all ports by Area ID and identifies prohibited ports. Those
columns are scrollable and swappable.

Figure 63 Port Connectivity Configuration table
To create or edit CUP port connectivity configurations, display the CUP Port Connectivity
Configuration list as shown in Figure 63. In this case, we have chosen to edit an existing
configuration.
The Create Port CUP Connectivity Configuration dialog displays all ports and port names on
the selected switch. The Block column, Prohibit column, and prohibited ports matrix display
as empty:
򐂰 Optional: Check the checkbox corresponding to a port that you want to block on the Block
column.
Repeat this step for all the ports that you want to block. Click the Block All checkbox to
block all ports.
򐂰 Optional: Check the checkbox corresponding to a port that you want to prohibit on the
Prohibit column.
Repeat this step for all ports that you want to prohibit. Click the Prohibit All checkbox to
prohibit all ports.
The cells in the matrix are updated with “X” icons to identify prohibited ports.
򐂰 Optional: Click the individual cells corresponding to the combination of ports that you want
to prohibit.
You cannot prohibit a port to itself.

Activating CUP port connectivity
When you activate a saved CUP port connectivity configuration on the switch, the preceding
configuration (that is to say the one that is currently active) is overwritten.
To activate a saved CUP port connectivity configuration, display the CUP Port Connectivity
Configuration list, click to select the saved configuration from the list, and click Activate.
Figure 65 on page 54 shows how we select the IPL CUP Port Connectivity Configuration and
activate it.

Fabric Manager FICON 5.2 Quickstart
Zoning and PDCM considerations
The FICON Prohibit Dynamic Connectivity Mask (PDCM) controls whether or not
communication between a pair of ports in the switch is prohibited or allowed. If there are any
differences in restrictions set up with zoning and PDCM, the most restrictive rules are
automatically applied.
You should configure all FICON devices in a single zone using the “Domain, Area” notation.
Then, you can use PDCM to “Allow” or “Prohibit” access between specific port pairs. PDCM
persists across a failover, because it is replicated at all times to the standby CP blade. The
active PDCM configuration is saved to the IPL if Active=Saved Mode has been enabled.
Displaying, configuring, disabling, and enabling ports
We will show you several of the functions that you can perform at a port level. First, we select
our fabric and then click the FC Ports tab, as in Figure 67, to list all of the ports in our fabric
(IP70).
Figure 67 FC Ports display for fabric
We can select the items that we want displayed by clicking on the column name and dragging
the column to where we want it. In Figure 68 on page 56, we have changed the display to
show Name, which is the Port worldwide name (WWN), and we have moved the State
column.
By default, the FICON-related fields are to the right and off the display so we recommend that
you drag them to the left so that they are always within view.
Fabric Manager FICON 5.2 Quickstart
55
Figure 68 Changing the order of the columns
You can click the columns to order the entries based on that column.
As you can see, the ports are identified by a WWN (its 8-byte hexadecimal representation) as
its predefined port name. The predefined port name has no information with respect to the
port itself or the connected devices. It makes sense to give it a meaningful name to identify
the port, the device that is connected to the port, or both. To assign a name to a port, we
highlight a port from the view, right-click, and then we get the pop-up window shown in
Figure 69 on page 57.
Note: A Port Type of “F” indicates that the connected device is either a FICON channel or
a FICON capable control unit.

Port swap
If a port malfunctions, or if you want to connect to different devices without having to rewire
your infrastructure, you can move traffic from one port to another port (swap ports) without
changing the I/O Configuration Data Set (IOCDS) on the mainframe computer.
Fabric Manager FICON 5.2 Quickstart

Fabric Manager launches the WebTools Port Management module to swap the ports.
WebTools automatically disables the ports prior to the swap and then re-enables them
afterwards. Use the following procedure to swap the area IDs of a pair of ports. To undo a
port swap, run the following procedure again on the same two ports.
Fabric Manager identifies swapped ports with “[swapped]” in the Area ID/Port Index column in
the FC Ports tab and in other tables where the Area ID/Port Index displays.
To start the process, highlight the port and right-click to display Port Swap as shown in
Figure 79.
