Network Configuration
Once the VMs have been deployed, the network configuration must be completed to connect them to the appropriate networks. The VMs are
configured with three vNICs and the network label is set to VM Network by default for all the three vNICs. The default configuration must be changed
as follows:
•
The first vNIC will be dedicated for use with management tools. It must be connected to a network allowing communication to the servers
running the HP 3PAR Management Console, remote CLI or client software accessing the CIM-API (SMI-S) or WS-API. Once configured, these tools
will connect to the 3PAR Simulator via the cluster IP address specified during the “Out of the Box” (OOTB) procedure.
•
(Optional) The second vNIC will be dedicated for use by Remote Copy if you plan on configuring two separate instances of the 3PAR Simulator to
leverage this capability. If Remote Copy is configured this interface must be connected to the Remote Copy network. This applies only to the
cluster nodes (sim_node0 & sim_node1) as the enclosure node (sim_esd) is not part of the Remote Copy network. The second vNIC in the
enclosure node (sim_esd) is unused and the network label can be left to the default VM Network.
•
The third vNIC must be connected to a private network connecting all three VMs (sim_node0, sim_node1 & sim_esd) with a virtual switch
(vSwitch). The virtual switch should not be connected to a physical adapter as the traffic will only be routed locally (assuming the VMs hosted on
the same ESXi) to allow communication between the three VMs in the 3PAR Simulator configuration. Follow the instructions below in Step 1:
vSwitch configuration and Step 2: Connect the third vNIC in each VM to the Private Network to set up the private network.
Step 1: vSwitch configuration
To configure a vSwitch:
•
Log in to the vSphere client and select your ESX host from the inventory panel
•
Click the “Configuration” tab in the right side top panel
•
Click on “Networking” in the Hardware frame
•
Click on “Add Networking” (top right corner)
•
Accept the default connection type, “Virtual Machine” and click “Next”
•
Accept the default “Create a vSphere standard switch”
•
Deselect the network adapter(s).
•
Example: If the adapter vmnic2 is selected, deselect it. (See Figure 1 below)
Figure 1 Sample vSwitch configuration with all adapters unselected
•
•
•
Click “Next”
Accept the default Network Label and VLAN ID None (0). Make note of the Network Label, this label must be selected in the next step to connect
the vNIC to the correct network
Click “Next” and then “Finish” to complete the vSwitch configuration (See Figure 2 below)
Figure 2 Sample vSwitch configuration
Step 2: Connect the third vNIC in each VM to the Private Network
Connect the third vNIC in each VM to the private network corresponding to the vSwitch created in the previous step.
To connect the vNIC:
•
Log in to the vSphere client and select the sim_esd VM from the inventory panel
•
Click the “Getting Started” tab (in the right page)
•
Click on “Edit virtual machine settings”
•
Click on the network interface “Network Adapter 3”.

Network Configuration using VMware Workstation
Once the VMs are deployed, the network configuration must be done to connect them to appropriate networks. The VMs are configured with three
vNICs and the network label is set to VM Network by default for all the three vNICs. The configuration must be changed as follows:
•
The first vNIC (Network Adapter in g
fi ure 4) will be dedicated for use with management tools. It must be connected to a network allowing
communication to the servers running the HP 3PAR StoreServ Management Console, remote CLI or client software accessing the CIM-API (SMI-S)
or WS-API. Once configured, these tools will connect to the 3PAR Simulator via the cluster IP address specified during the “Out of the Box” (OOTB)
procedure.
•
(Optional) The second vNIC (Network Adapter 2 in figure 4) will be dedicated for use by Remote Copy if you plan on configuring two
separate instances of the 3PAR Simulator to leverage this capability. If Remote Copy is configured this interface must be connected to the
Remote Copy network. This applies only to the cluster nodes (sim_node0 & sim_node1) as the enclosure node (sim_esd) is not part of the
Remote Copy network. The second vNIC in the enclosure node (sim_esd) is unused and the network label can be left to the default VM Network.
•
The third vNIC (Network Adapter3 in figure 4) must be connected to a private network connecting all three VMs (sim_node0, sim_node1 &
sim_esd) with a Lan Segment for traffic to be routed locally, allowing communication between the three VMs in the 3PAR Simulator
configuration. Follow the instructions below in Step 1: Configuring a LAN Segment and connecting vNIC to the LAN Segment Network to set up the
private network.
Step 1: Configuring a LAN Segment
To configure a LAN Segment:
1. Launch VMware Workstation
2. Right-Click on sim_esd, select “Settings”
3. Click on “Networking Adapter 3” in the Hardware frame
4. In the Network Connection frame, select LAN Segment
5. Click on the tab below that says “LAN segment”. A global LAN Segments Window will pop up
6. Click “Add” and enter a name for the LAN Segment
Example: Simulator
7. Ensure that the Network Adapter 3 is connected to the LAN Segment you just created by selecting it using the drop down menu (See Figure 4
below)
8. Click “OK”
Technical white paper
Page 8
Figure 4 Virtual Machine Settings - LAN segment selection for Network Adaptor 3
Important
Repeat the above steps to connect Network Adapter 3 for both sim_node0 & sim_node1 to the LAN segment
Step 2: Configuring a management network.
In order to use the HP 3PAR StoreServ Management Console or 3PAR remote CLI on the system that is running VMware Workstation and hosting the
3PAR Simulator instance, or another VM instance you will need to configure Network Adapter 1.

Right-Click on sim_node0, select “Settings”
Click on “Network Adapter” in the Hardware frame
In the Network connection frame, select “Host-only”
Click “OK”
Click the "Edit" option at the top menu
Click "Virtual Network Editor”
Select the host only type VMnet
Note the Subnet Address and the Subnet Mask. You will need this later during the OOTB process when configuring the node IP address
that talks to the StoreServ Management Console, CLI Utility, Putty, etc.
After creating the “Host Only Network” you may need to reboot your machine in order to initialize the network stack. Few users running VMware
Workstation 10 have reported that is the only way they could get the network to work in their case.
Technical white paper
Page 9
Figure 5 Virtual Machine Settings - Host only selection for Network Adaptor 1
Important
During the “Out Of The Box” (OOTB) procedure, you will need to provide a Static IP and the same subnet mask to be able to communicate with the HP
3PAR Simulator storage system instance form the 3PAR StoreServ Management Console on your laptop or on a separate VM as well. Please refer to
the SSMC documentation for resources requirement
Note
Note about VMware Networking: When you assign a Host-Only network profile to a specific VMNetx , VMware Workstation will
automatically create a new Class C Subnet for that VMnet (i.e. 192.168.x.x) Every installation is different, so it is important to check
what subnet is actually in use on your machine using the VMware Networking Editor Utility (under Edit on the top menu of VMware
Workstation home page). This network will by default have DHCP turned on (assigning addresses from .128 through .254), as well as
a default gateway of .1 on that subnet.
In most cases, VMware Workstation install would create VMNet1 interface on your system. The default IP assigned to the VMnet1 interface is:
192.168.80.1. THIS IS NOT AN IP ADDRESS YOU ASSIGN TO THE 3PAR SIMULATOR.
Example:
In this case the IP address of 192,168.80.10 and subnet mask of 255.255.255.0 have been assigned to the HP 3PAR Simulator node during OOTB
procedure.

Step 1: Start the esd daemon
Log in to the VM deployed with the esd package with user root password root
Run createcages to create the desired cage configuration.
The createcages utility will display the following menu:
Choose from the menu:
1. 1 cage, 24 HDDs
1 DCN2 cage with 24 FC drives
2. 4 cages, 96 HDDs
1 DCN2 cage with 12 FC drives and 12 SSD drives
2 DCS8 cages with 12 FC drives and 12 SSD drives each
1 DCS7 cage with 12 NL drives and 12 SSD drives
3. 4 cages, 48 HDDs
1 DCN2 cage with 12 FC drives
3 DCS8 cages with 12 FC drives each
4. 4 cages, 96 HDDs
1 DCN2 cage with 12 FC drives and 12 SSD drives
3 DCS8 cages with 12 FC drives and 12 SSD drives each
5. exit (you can create cages using esd)
Select a number(1-5) to create cages and then exit
Once you have the HDW configured, you must start the esd daemon by running the command esd.
See the section Error: Reference source not found for more information on how to manage cages & disks using esd.

b) Assign the same serial number to this node as the one you assigned 2-b ( 1699678 or 1699679 )
c) Confirm ‘y’
Important
•
The serial number must be the same for both nodes in a simulator instance
•
One of the two serial numbers must be used in order to activate the preloaded licenses. Failing to use one the serial numbers will leaded to
an instance where no license is applied and you would have to re-install.

Follow the prompts to finish the configuration using the information you collected in the Simulator Setup section.
When OOTB completes, the HP 3PAR Simulator storage system cluster node configuration is done.
See the section Error: Reference source not found for more information on how to manage cages & disks using esd.
Step 3: Verifying the configuration
1. Open the HP 3PAR Management Console
2. Connect to the cluster node IP address
3. Login with user 3paradm password PTzk5fVt

Simulator Best Practice
1.
2.
3.
Unless the entire storage system (cluster nodes and esd node) is being brought down or restarted, do not terminate the esd daemon alone
while the nodes are up and running. Terminating the esd daemon has the effect of disks going offline leading to TOC quorum loss and
eventually the nodes go into power fail mode.
Gracefully shutdown the HP 3PAR Simulator by first shutting down the cluster nodes, then stop the esd daemon and shutdown the esd VM.
Use the following steps:
A. Login to node 0 as user 3paradm and password PTzk5fVt
B. Issue the command
shutdownsys halt
C. Once the cluster node VMs (node 0 and node 1) are powered down:
i. login to esd VM as user root password root
ii. Issue the command
esd stop
D. Once the daemon is stopped, issue the command
shutdown –h 0
When powering back up the HP 3PAR Simulator you need to:
A. Bring the esd VM first and start the esd daemon
B. Then power up both the cluster nodes.
Enclosure and Cage Configuration
Start the Daemon
You can start the daemon by running either of the following commands:
esd
esd start
esd data directory: /common/esd/.esddata
The esd maps each disk to a file. By default, all data files are created in a directory called .esddata under /common/esd.
You can override the default parent directory /common/esd when you start esd using the –l option:
esd start –l <new-dir>
Stop the Daemon
You can stop the daemon by running the following command:
esd stop
Note
You cannot start esd again without stopping it first as only one instance of esd can be running at any time
Cage WWN and Disk WWN
Some of the subcommands require cage WWN or disk WWN to perform the requested operation. The esd automatically generates cage WWN and
disk WWN when a new cage or disk is added. You can use the list command described later in the section to get the WWNs.
Add a Cage
Synopsis:

For the first cage configuration, the parameter cage-type is optional. By default the first cage created will be DCN2 with FC drives. A user is
allowed to override the default by specifying the cage-type and/or disk-type. The parameter cage-type is mandatory for additional cages.
The version 1.2 release of HP 3PAR Simulator supports only a 2-node cluster, so you can configure only one DCN2 cage with the simulator. If
you need to configure more than one cage, use cage types DCS7 or DCS8.
If the parameter disk-type is not specified, the following defaults will apply for each cage type:
a. DCN2 and DCS8 cages: FC
b. DCS7 cage: NL
If the parameter disk-num or mag-num is not specified, the default number is 24.
The simulator supports up to 4 cages with at most 48 disks. For example, a configuration with 2 cages and 24 disks per cage or 4 cages with
12 disks per cage has reached the limit. Additional cages/disks cannot be added until some disks are deleted.
Examples:
1.
Add the first cage with the default configuration:
# esd add cage node=vm-a node=vm-b
Note
The above command adds a DCN2 cage with 24 FC drives, connecting to cluster nodes vm-a and vm-b
2.
Add the first cage or additional cage by specifying cage-type:
# esd add cage cage-type=DCS8 node=vm-a node=vm-b
Note
The above command adds a DCS8 cage with 24 FC drives, connecting to cluster nodes vm-a and vm-b
3.
Add an additional cage by specifying cage-type, disk-type, and disk-num:
# esd add cage cage-type=DCS8 disk-type=SSD disk-num=12 node=vm-a node=vm-b
Note
The above command adds a DCS8 cage with 12 SSD drives, connecting cluster nodes vm-a and vm-b
Add Magazine(s)
Synopsis:
esd add mag -w <cage-wwn> [disk-type={FC|SSD|NL}] [mag-num=<num>]
-w <cage-wwn> specifies the associated cage to add the magazine
mag-num
specifies the number of magazines to create, default: 1
disk-type
specifies the type of disks to create, default depends on the type of the cage
See the section Add a Cage
Examples:
1. add two magazines with default disk-type:
# esd add mag –w 50050cc2fc464dc4 mag-num=2
The above command adds two magazines to the cage with wwn 50050cc2fc464dc4. If the cage is DCN2 or DCS8, FC drives will be added. If
the cage is DCS7, NL drives will be added.
2. Add 1 magazine with SSD drive:
# esd add mag –w 50050cc2fc464dc4 disk-type=SSD
The above command adds 1 magazine with SSD drive to the cage with wwn 0x50050cc2fc464dc4. If the cage is DCS7, this operation will fail
because DCS7 doesn’t allow SSD drives.

Add Disk(s)
Synopsis:
esd add disk -w <cage-wwn> [disk-type={FC|SSD|NL}] [disk-num=<num>]
-w <cage-wwn> specifies which cage to add the disk
disk-numspecifies the number of disks to create, default: 1
disk-type
specifies the type of disks to create, default depends on the type of the cage
See the section Add a Cage
Examples:

2.
Add 8 disks with default disk-type:
# esd add disk –w 50050cc2fc464dc4 disk-num=8
The above command adds 8 drives to the cage with the wwn 50050cc2fc464dc4.
If the cage is DCN2 or DCS8, FC drives will be added, if the cage is DCS7, NL drives will be added.
Add 1 NL drive:
# esd add disk –w 50050cc2fc464dc4 disk-type=NL
The above command adds 1 magazine with SSD drive to the cage with the wwn 50050cc2fc464dc4.
If the cage is DCS8, this operation will fail because DCS8 doesn’t allow NL drives.
Delete a Cage
Synopsis:
esd delete cage -w <cage-wwn>

ESD Log FIles
The esd log file location is /var/log/esd. It logs the following information in the esd.log* files:
•
Daemon start/stop time along with its pid
•
connections with vhba
•
errors
The esd keeps last 5 log files (from esd.log.0 to esd.log.4). The esd.log has the most recent information. If a change configuration fails, check esd.log
for errors.
Exporting Virtual Volumes
The HP 3PAR Simulator environment does not support a host entity. To export volumes to a host, a fake host entity must be created. The
simulator provides FC (Fibre Channel) ports for the fake host to connect and simulate host connectivity only, host I/O is not supported with this
connection.
Before exporting a virtual volume, you need to simulate the host connection.
1. Log in to a cluster node with user console and password crH72mkr
2. Choose option 3 (Simulator Host Connection), this will create a host WWN.
You can then use the 3PAR Management Console or Remote CLI to create host attributes and export the volume. If you use Remote CLI, run
showhost to find the host WWN. The host WWN must be used with the createhost command.
Note
1. The host connection simulation is an internal utility and may be changed/obsoleted in the future releases of HP 3PAR Simulator.
2. The simulated host connections once created they can not be deleted.
3. The simulator host connections are not persistent through simulator reboots. they are automatically removed upon rebooting the nodes

Refer to CLI Administrator's Manual for the full syntax of the commands createhost, createvlun to export volumes. See the section Error:

Remote Copy
Remote Copy allows copying virtual volumes from one storage system to another.
With the HP 3PAR Simulator:
• Only Remote Copy over IP (RCIP) and a 1:1 configuration is supported
•
•
Any RC configuration that requires more than 2 nodes in a cluster is not supported
Assign one of the two supported serial numbers to each instance of the simulator. The serial number assignment is part of the cluster node
configuration & setup, ensure the same serial number is assigned to both the cluster nodes in the same instance of the simulator.
Requirements
To run a 1:1 RCIP configuration in a server or workstation environment, your system needs to be able to support:
•
A total of 6 VMs, three VMs for each simulated storage system.
•
The cluster node VMs require 2 vCPUs and 4GB memory each.
•
The two instances of the simulator can be run in a single system or two different systems. The RC network connectivity between the two
simulator instances must be setup via a separate vSwitch on ESXi or LAN segment on VMware Workstation 9. The vNIC#2 in each of the cluster
nodes must be connected to the vSwitch or the LAN segment.
The following requirements are general RC requirement, not specific to simulator:
•
one static cluster IP address for each cluster
•
One static IP address for each RC port, the RC IP address must be in a different subnet than the primary node and cluster IP address (vNic#2 in
each cluster node VM).
Configuration
Follow instructions in RC user guide to setup the RC over IP configuration. See the section Error: Reference source not found for reference to the
RC user guide.
As an example, the section below in the document is to illustrate how the RCIP can be setup using the HP 3PAR CLI. Users might choose differtent
IPs and subnet masks.
Important
In the following instructions, Cluster A refers to the 2-node cluster in Storage System 1 and Cluster B refers to the 2-node cluster in Storage
System 2
Cluster A:
First setup the netc configuration to configure cluster IP; this is required for the RC commands to work
netcconf -set
Follow the prompts to enter IP address, subnet mask and gateway address
To verify the configuration, use the command shownet
RC configuration:
controlport rcip addr 192.1.82.75 255.255.248.0 0:3:1
controlport rcip addr 192.1.82.76 255.255.248.0 1:3:1
controlport rcip gw 192.1.80.1 0:3:1
controlport rcip gw 192.1.80.1 1:3:1
Use showport –rcip to verify the RC port information

createcpg -ha mag -sdgs 16g -sdgl 32g -sdgw 24g cpg1
createvv -snp_cpg cpg1 cpg1 rvv1 10g
Cluster A:
To create an rcopy group and admit rcopy VV:
creatercopygroup rc_group1 srcp2:periodic
admitrcopyvv vv1 rc_group1 srcp2:rvv1
Start initial replication:
startrcopygroup rc_group1
Use showrcopy to display the status of the replication
To resync:
syncrcopy rc_group1
Use showrcopy to check the status of the replication
The HP 3PAR Management Console can also be used to configure RCIP. Please refer to the Remote Copy and Managemement user guides for more
information.
