Introduction
Identify the DCA Software Version
The replacement procedures in this guide only pertain to DCA clusters with software version 1.0.3.x. DCA documentation is tied to a version of the DCA Software. Before beginning any replacement procedure on a DCA, you should verify the software version matches the version of guide you are using.
Perform the following steps to identify the DCA Software Version:
1. Log into the Primary Master Server of the DCA as the user root. For instructions on how to log in to the server from your laptop, refer to “How to Connect to the DCA in the Field” on page 108.
2. View the contents of the /opt/greenplum/conf/build‐version.txt file. Verify the ISO_VERSION value is 1.0.3.x
# cat /opt/greenplum/conf/build-version.txt
ISO_BUILD_DATE="Fri Mar 11 12:01:37 PST 2010"
ISO_VERSION="1.0.3.0"
ISO_BUILD_VERSION="9"
3. If the version displayed is not 1.0.3.x, download the documentation from Powerlink for that software version.

Introduction
Avoiding
Electrostatic
Discharge Damage
(ESD)
When replacing or installing field replaceable units (FRUs), inadvertent damage to the sensitive electronic circuits in the equipment can occur simply by touching them. Electrostatic charge that has accumulated on your body can discharge through the circuits. If the air in the work area is dry, running a humidifier in the work area can help decrease the risk of electrostatic discharge (ESD) damage.
Read and understand the following guidelines:
20

Provide enough room to work on the equipment. Clear the work site of any unnecessary materials or those that naturally build up electrostatic charge such as foam packaging, foam cups, cellophane wrappers, and similar items.

Do not remove replacement or upgrade FRUs from their antistatic packaging until you are ready to install them.

Set up your EMC‐issued ESD kit and all other materials needed before servicing a Greenplum system. Once servicing begins, avoid moving away from the work site; otherwise, your body can build up an electrostatic charge.

Use the ESD kit when handling system components.

Use an ESD wristband. Attach the clip of the ESD wristband to any bare (unpainted) metal in the bay; then place the wristband around your wrist with the metal button against your skin.

Dell PowerEdge R610 Master or Standby Server
Overview
Replacing the Primary or Secondary Server (Dell R610) involves removing the failed server from the cabinet, moving its hard disks to the replacement server and installing the new Master server to the cabinet in the same slot as the old server.
To resume operation of the Greenplum Database, a manual failover process needs to be executed on the Standby Server. Once the database is back online, then the Primary Master can be replaced. To get the Greenplum Database back into operation, you need to activate the Standby Server in its place. Once the database is back online using the Standby Server, then you can replace the server.
Tools
The following tools are required:

#2 Phillips screwdriver

Wrist grounding strap
Service Tag
Location
When replacing any hardware component, it is important to properly de‐brief the part. The Master Server serial number tag is located on a pull‐out tab on the bottom left corner of the server.
Identify DCA
Software Version
Before continuing with the replacement, verify the DCA Software version is 1.0.3.x. Follow the steps in “Identify the DCA Software Version” on page 18.

Replacing Dell R610 Primary Master and Standby Master Servers
There are three scenarios for replacing the Master Servers as detailed in the following sections:

“Scenario 1: Standby Master is Active — Must Replace Primary Master” on page 34

“Scenario 2: Must Replace Primary Master — Still Serving As Active Master” on page 38

“Scenario 3: Must Replace Standby Master — Primary Master is Active” on page 39

“Scenario 4: No Greenplum Database is Initialized ‐ Must Replace Primary or Standby Master Server” on page 41

Dell PowerEdge R610 Master or Standby Server
Scenario 1: Standby Master is Active — Must Replace Primary Master
The following scenario will occur if remote support has performed a Standby Master failover. You will need to replace the failed server and fail back so each server retains its primary role.
1. Activate the server identification light on the Primary Master Server by pushing the button on the front or back panels of the server. This causes the LCD panel on the front, and the system status indicator on the chassis back panel, to flash blue until you push one of the buttons again.
2. If the failed Primary Master Server is accessible through SSH, log into the server as the user root. If the Primary Master Server is NOT accessible through SSH, skip to step 4.
For instructions on how to log in to the server from your laptop, refer to “How to Connect to the DCA in the Field” on page 108.
3. Issue the following command to shutdown the server:
shutdown -h now
4. If the server is not accessible through SSH, shutdown the server by pressing the power button.
Note: If you experience performance issues with the Dell iDRAC Virtual Console (for example, slow/delayed keystroke response), see “Using the iDRAC Serial Console Emulator” on page 129 to configure an alternate connection method.
5. Label and disconnect all cables from the server you are replacing.
6. Remove the failed server from the rack. See “Removing the Server from the Cabinet” on page 46 for details.
The server is very heavy. EMC recommends use of a lift‐tool or two service personnel when removing servers.
7. Install the replacement server into the rack. See “Installing the Replacement Server into a Rack” on page 45 for details.
8. Swap one drive slot at a time between the failed Segment Server and the replacement server.
IMPORTANT
Use caution and be careful when swapping drives. Only swap one drive at a time.
9. Connect the power, ethernet, and twin‐ax cables to the new server. Refer to your cable labeling to ensure correct positioning.
10. From the working master server, issue the following commands to identify the IP address of the new server:
# service dhcpd stop
# service dhcpd start
# tail /var/log/messages

84:2b:2b:15:b4:2d (idrac-B7DKXP1) via eth0
The value in BOLD is the IP Address that was assigned to the new hardware. Use this IP Address to connect to the server’s iDRAC port.
11. Set the iDRAC IP address from its manufacturing default of DHCP to the IP
address for mdw - 172.28.0.250. For details, refer to “Reconfiguring iDRAC IP Address” on page 115
12. Log back into the iDRAC through its correct IP address. Under the Virtual Console Preview section, click Launch. The console viewer opens.
13. Click OK if any security warnings appear in your web browser.
14. Select Power > Power On System. Click OK. The system will begin to boot.
15. Upon boot, the system displays an error indicating that it has found a foreign disk configuration. Figure 7
Foreign Disk Configuration — First Message Prompt
16. Press the F key to import the configuration. The replacement server might reboot after the import.

DCA Segment and DIA Server Replacement
Replacing the Dell R510 DCA Segment and DIA Server
Total server failure is when all segments on that host are down and those segments fail over to the mirrors. Total server failure causes all Greenplum Database Segment Instances to fail over to their mirror Segment servers. On a Greenplum DIA, server failure will result in degraded performance as the loading processes on the DIA host will be unavailable. Replacing the Dell PowerEdge R510 server involves removing the failed server from its chassis then removing the disk drives and installing them in the new server. Note: This procedure requires a brief Greenplum Database downtime if replacing a Segment Server. Verify that the customer is aware of the downtime and that the replacement schedule is agreed upon. There is no downtime to the Greenplum Database if an Greenplum DIA server fails.
Tools
The following tools are required:

#2 Phillips screwdriver

Wrist grounding strap
Service Tag
Location
When replacing any hardware component, it is important to properly de‐brief the part. The segment and DIA servers serial number tag is located on a pull‐out tab on the bottom left corner of the server.
Identify DCA
Software Version
Before continuing with the replacement, verify the DCA Software version is 1.0.3.x. Follow the steps in “Identify the DCA Software Version” on page 18.

DCA Segment and DIA Server Replacement
Reseat Cables before Replacement
Before replacement of a segment or DIA server, cables should be removed and re‐connected to validate the issue the server is experiencing isn’t due to a faulty connection. Perform these steps before continuing with replacement.
1. Activate the server identification light by pushing the button on the front or back panels of the server (large button with the letter “i” on it).
Note: If the server is completely non‐operational, the light might not work.
2. Connect your service laptop to the DCA as described in “Connecting to the DCA from a Workstation” on page 107.
Note: If you experience performance issues with the Dell iDRAC Virtual Console (for example, slow/delayed keystroke response), see “Using the iDRAC Serial Console Emulator” on page 129 to configure an alternate connection method.
3. Login to the Primary Master Server as the user root (for example, use IP Address 172.28.4.250).
4. Power down the server. 
If the server can be accessed by SSH: Enter the following command. Replace the hostname in BOLD with the hostname of the segment server you are working on:
# ssh sdw1
# shutdown -h now

If the server cannot be accessed by SSH: Verify it is powered down, use the power button on the front of the server if necessary.
5. Once the server is powered off, unplug and reconnect the admin network cable, two interconnect cables, and two power supply AC cables. Figure 22 shows the connections which should be reseated.
Figure 22
Reseat cables connected to server ports
6. Power on the server by pressing the power button located on the front of the server.
7. Wait 5 minutes for the server to boot ‐ from the Primary Master server, issue the ping command to each interface of the server. Replace the text in BOLD with the hostname of the server you are working on:
# ping sdw1-cm
# ping sdw1-1
Reseat Cables before Replacement
53
DCA Segment and DIA Server Replacement
# ping sdw1-2
8. If there is no response, the server should be replaced. If the server can be reached on ALL interfaces, a replacement is not necessary. Issue the commands below to recover the segment instances ‐ this does not apply if the server is part of a DIA.
# su - gpadmin
$ gprecoverseg
$ gpstop -r
Note: The step in italics will restart the Greenplum Database. Verify this is OK with the customer before issuing the gpstop command.
Replacing a Failed Segment/DIA Server
Follow one of the procedures below based on the failure scenario of the server:
The Failed Server is
running an Active
Greenplum
Database

“The Failed Server is running an Active Greenplum Database”

“The Failed Server is NOT running an active Greenplum Database”
This procedure should be followed on a Segment Server that was part of a DCA running Greenplum Database. This procedure includes instructions to replace the server hardware as well as Greenplum Database commands that must be run to recover segment instances.
1. Activate the server identification light by pushing the button on the front or back panels of the server (large button with the letter “i” on it).
Note: If the server is completely non‐operational, the light might not work.
2. Connect your service laptop to the DCA as described in “Connecting to the DCA from a Workstation” on page 107.
Note: If you experience performance issues with the Dell iDRAC Virtual Console (for example, slow/delayed keystroke response), see “Using the iDRAC Serial Console Emulator” on page 129 to configure an alternate connection method.
3. Login to the Primary Master Server as the gpadmin user (for example, use IP Address 172.28.4.250).
4. If the server you are replacing is in the Greenplum DIA, skip to Step 6.
5. Perform one of the following actions:
If the Segment Server is still accessible via SSH:
1. Confirm that the mirrors are synchronized for that server by running the
gpstate -m command on the Master Server. 2. Verify that the Data status column indicates that the mirrors for the server being taken offline are synchronized.
54
Replacement of Field Replaceable Units — EMC Greenplum DCA
DCA Segment and DIA Server Replacement
Note: If the mirrors are not synchronizing, contact the EMC Support Lab.
If the server has failed completely:
1. Run the gpstate -s command on the Master Server to confirm that the Greenplum database has marked the Segment Server as down. 2. In the output, locate the Segment Server that has failed and verify that the Segment status row displays “Down in configuration.” This means that the Greenplum database has identified the server as failed.
6. Power down the failed server.
7. Label and disconnect cables from the failed server.
8. Remove the failed server from the rack. See “How to Install and Remove a Server to and from the Rack” on page 64 for details. The server is very heavy. EMC recommends use of a lift‐tool or two service personnel when removing servers.
9. Install the new server into the rack.
10. Swap one drive slot at a time between the failed Segment/DIA Server and the replacement server.
IMPORTANT
Use caution and be careful when swapping drives. Only swap one drive at a time.
11. Connect the power, ethernet, and twin‐ax cables to the new server. Refer to your cable labeling to ensure correct positioning. DO NOT POWER ON THE SERVER.
12. From the master server, issue the following commands to identify the IP address of the new server:

Replacing a Drive in the Dell R610 Master or Standby Server
Replacing a drive on a Primary Master or Standby Server (Dell 600 KB 10 K RPM SAS 2.5‐inch disk drive in an 11 G disk sled) consists of the following tasks:

Identifying the failed drive

Replacing the failed drive
All drives are installed at the front of the server and connect to the system board through the SAS backplane. Hard drives are supplied in special hot‐swappable hard‐drive carriers that fit in the hard‐drive bays. Use only drives that have been tested and approved by EMC for use with the SAS backplane board.
Use appropriate ESD precautions, including the use of a grounding strap, when performing the drive replacement procedure. Identifying the Failed Drive
Before you can replace the failed drive, you must confirm which drive has failed and confirm the drive specified for replacement is the failed drive.
1. Activate the server identification light by pushing the button on the front or back panels of the server. This causes the LCD panel on the front and the system status indicator on the chassis back panel to flash blue until you push one of the buttons again. 2. Notice that each drive sled has LED indicators that show the current status of the drive. A failed drive has an amber LED indicator or the green indicator flashes with a fixed, regular interval.
3. If your information from the dial‐home contains a drive number, reference the diagram below for drive position information in the Dell R610 chassis:


Identifying the failed drive

Replacing the failed drive
Note: A single disk failure should not cause a segment to go down if using RAID; however, there might be a performance impact.
All drives are installed at the front of the server and connect to the system board through the SAS backplane ‐ the backplane is compatible with SATA and SAS drives. Hard drives are supplied in special hot‐swappable hard‐drive carriers that fit in the hard‐drive bays.
Use only drives that have been tested and approved for use with the SAS backplane board.
Do not turn off or reboot your system while the drive is being formatted as this can cause a drive failure. Use appropriate ESD precautions, including the use of a grounding strap, when performing the drive replacement procedure. Identifying the
Failed Drive
Before you can replace the failed drive, you must identify which drive has failed. 1. Activate the server identification light by pushing the button on the front or back panels of the server. 2. Notice that each drive sled has LED indicators that show the current status of the drive. A failed drive has an amber LED indicator or the green indicator flashes with a fixed, regular interval.

Replacing a Server Power Supply in the Dell R610
The server is powered by redundant, hot‐swappable power supplies (Dell R610 717 high‐output power supply) that slide into the rear of the server chassis. Once you have identified the failed power supply, you can replace it and return the system to normal operation.
This section describes how to replace a failed power supply.
Replacing a server power supply consists of the following tasks:

Identifying the failed power supply

Removing the power supply

Replacing the power supply
Note: The power supplies are “hot‐swappable” and can be replaced during normal system operation.
Use appropriate ESD precautions, including the use of a grounding strap, when performing the power supply replacement procedure. Identifying the
Failed Power Supply
1. Verify the power supply that has failed. The server power supplies have LED indicators that turn amber when the power supply has failed. The LED on a failed power supply may not display any light depending on how badly the power supply has failed.
2. Activate the server identification light before starting any service by pushing the button on the front or back panels of the server.
3. Verify that the LED on the redundant power supply is green.
On the R610s, a server that has a failed component does not have a blue light on the left of the server. See Figure 34.

Resynchronzing the
Database After
Replacing a Switch
When one of the DCA interconnect switches fails, you should still have a Greenplum Database system up and running. There are two interconnect networks, and the initialization process makes sure that a primary and its corresponding mirror are on different networks (switches). This section does not apply during a switch failure of a Greenplum DIA.
A switch failure means that half of the Greenplum segment instances go down, and all database processing of those down segments fails over to the mirrors. With a switch failure you are going to have several segment servers performing double‐duty. Users might experience slower response times. 1. After replacing the switch, SSH into the Master Server and run the following command:
gprecoverseg
2. Enter Y when prompted to continue.
3. Once the gprecverseg command is completed, check the state of the ʹResynchronizationʹ process, enter the following command:
gpstate -m
4. Run the following command until the status displays as synchronized.
gpstate -m
5. Allow a few minutes for the synchronization. Once complete, the status displays as synchronized. This means that the primary and mirrored segments are synchronized.
6. Enter the following command to return all segments to their preferred role:
gpstop -r
The switch replacement is now complete.

Replacing the Brocade 8000 Power Supply
The Brocade 8000 has two power supplies.
Disassembling any part of the power supply voids the part warranty and regulatory certifications. There are no user‐serviceable parts inside the power supply. The cooling system relies on pressurized air; do not leave either of the power supply slots empty longer than two minutes when the switch is operating. If a power supply fails, leave the power supply in the switch until it can be replaced. Maintain both power supplies in operational condition to provide redundancy.

How to Connect to the DCA in the Field
Requirements
You must have the following hardware and software tools to make the connection:

Workstation (for example, a laptop) that has a standard, RJ‐45 Ethernet port is required — The operator of the workstation must have the authority to manipulate the network interface to set IP address information.

The workstation must have an SSH, SCP and Telnet client — The Macintosh OS includes these tools. For Windows, Putty, and WinSCP are recommended. 
A basic knowledge of how to operate in a Linux environment — It is helpful to have an understanding of navigating and editing files in Linux.
In addition to the requirements listed above, there is information about the site that must be confirmed prior to beginning any work on a DCA:

Determine whether the administration network (the AT9924TL switch or switches) has been connected to the customer network — If so, it is advisable to temporarily disconnect the customer network and the DCA administration network during service.Some service procedures include the use of DHCP from the cluster master node. Having an unanticipated DHCP server that is can be seen from the customer network can interfere with unrelated activities on the customer network.

Determine whether or not the administration network IP address scheme has been changed — Customers occasionally change the IP addresses of iDRACs (an iDRAC is the remote management interface on each server) or the first network interface on each server. It is important to know both the IP addresses scheme and the subnet masks used. Without this information, it is not possible to establish a viable connection to the DCA. All service activities for the Greenplum DIA should be done by connecting to the master server of the DCA. 108

Note: The first built‐in port on each server is both the first network interface in the operating system (eth0) and the network interface for the iDRAC. This port has two IP addresses, but only the eth0 address can be used to copy files to or from the DCA. The iDRAC address provides out of band access to each server’s console making it unnecessary to use a physical monitor and keyboard attached to the servers themselves.
If the customer has altered the addresses or netmasks, it is important to replace the information in the table above with the new addresses and netmasks so that an open address can be found for use on the engineer’s workstation and the appropriate netmask is used on that workstation.
Connecting to the DCA
Note: Unless otherwise specified, all connections to the scale out rack (GP1000+1) and Greenplum DIA should be done through the first DCA rack administration switch (i‐sw‐1).
1. Connect the service cable (a red, cat6 cable connected to port 23 of the AT9924TL switch at the top of the first rack) to the engineer’s workstation.
2. Assign the network interface on the workstation an IP address of 172.28.3.253 with a netmask of 255.255.248.0 and no gateway. Note: If the customer has changed the IP address scheme, work with the customer to determine an appropriate IP address and gateway.
3. Open a terminal emulation program (such as Putty). Connect through SSH to the desired server. For example, suppose you want to connect to the operating system of sdw14. Enter the IP Address of the server in the Host Name field and click Open.

Description
Browsing to the iDRAC address
(https://172.28.0.x by default) provides a
graphical interface into the systems management
facility.
Hardware information and status is available
through web browser interface. You can open a
virtual console, which emulates a KVM by clicking
the Launch Virtual Console button on the main
page.
Note: You can also remotely connect to the
iDRAC web interface. See “Accessing the iDRAC
Web Interface with SSH” on page 123 for more
information.
iDRAC, Serial
ssh
The serial interface into the iDRAC is accessible
by making an SSH connection to the iDRAC. For
example, running the SSH command
root@172.28.0.251 opens a connection to
smdw’s iDRAC. This interface is a command-line
interface and starts by giving a command prompt
of admin1>.
The following commands are helpful in this
interface:
• start /admin1 starts a powered off server
• stop /admin1 forces a running server to stop
• reset /admin1 forces a server to power cycle
• console com2 connects to the server’s serial
console. The user can log in to the OS from
here and perform tasks even if the operating
system is in single-user mode or the OS has
not configured it network interfaces. Finally,
the server POST can be monitored here.
Operating System,
network
ssh
Through this connection, files can be transferred
and any other work that does not require the
features of the console can be performed. In
most cases, this is the connection that should be
used.

Reconfiguring iDRAC IP
Address
When DCA replacement servers are initially configured, their iDRACs have an IP address of 192.168.1.100. To reconfigure the network settings, perform the procedure described in “Configuring iDRAC IP Address Through HTTP”. To reconfigure the iDRAC IP address in a situation where the default IP address is not connecting or is unknown, perform the procedure described in “Configuring iDRAC IP Address if the Default IP is Unknown”.

Configuring iDRAC IP Address Through HTTP
When DCA and DIA replacement servers are initially configured, their iDRACs will have an IP address set to DHCP. To reconfigure these with your service laptop, perform this procedure.
Note: If you are replacing a server, do not turn the server’s main power on, but do connect the power, Ethernet, and twin‐ax cables to the new server.
1. Connect the service laptop to the red or white service cable attached to port 23 or 24 of the DCA administration switch. Assign the service laptop an address of 192.168.1.200 with a netmask of 255.255.255.0 and no gateway. If the connection fails, change the service laptop IP address to 192.168.1.201 to rule out a potential IP conflict between the service laptop and replacement server. If the connection continues to fail after this change, refer to “Configuring iDRAC IP Address if the Default IP is Unknown” on page 120 for additional instructions.
2. Open a web browser and navigate to the IP Address of the new server. For
example, if the new server’s IP address is 172.28.4.197, navigate to
https://172.28.4.197.

You are connected to the customer network locally and have access to the DCA through its external interface.

You are connected to the customer network remotely (Webex or ESRS) and have access to the DCA through its external interface.
Do not use SSH if you can connect to the DCA through the red service cable. Also, you cannot use SSH to access to the Dell iDRAC web interface on the server through which you are connected. For example, if you are connected to the primary master server, you cannot access the Dell iDRAC web interface on the primary master server; You can access Dell iDRAC on the standby master server.
1. Open the Putty client and establish an SSH connection to the primary or standby master server.
2. Click the icon in the top‐left side of the Putty window and select Change Settings.

Using the iDRAC Serial
Console Emulator
Dell’s iDRAC controller includes a serial console emulator accessible that you can access with SSH. You can use the emulator to view boot information before the operating system loads. The output from the serial console emulator is consistent with the output from COM port redirection. You can establish a connection to the Dell iDRAC Serial Console Emulator locally through the admin switch, or remotely through an SSH tunnel.

Using the Serial Console Emulator
You can use the iDRAC Serial Console Emulator at any time to view console output. EMC recommends using the emulator under the following scenarios: 
The remote connection to the DCA is slow and causing performance issues when using the iDRAC Virtual Console.

The Virtual Console is exhibiting inconsistent behavior, such as discarding keystrokes, or timing out.
The Dell iDRAC Serial Console Emulator displays a text‐only output and might cause characters to display incorrectly in menu interfaces or during some sections of POST.
1. Establish an SSH connection to the service port of the server you want to access. • Local: If you are connected to the system from the red service cable, open the Putty telnet/SSH client and connect to 172.28.0.# as user root.
where # is the server number. For example, the destination IP address for segment host sdw7 would be 172.28.0.7.
• Remote: If you in a remote location and away from the system, establish a connection to the system (by default, this occurs on the primary master server), then enter the following command: ssh root@sdw#-sp
where # is the server number. For example, the destination IP address for segment host sdw7 would be 172.28.0.7.
2. When prompted for a password, enter calvin.
When the connection establishes, the following prompt displays:
/admin1->
Note: After successfully connecting, you might need to press the ENTER key to refresh the screen.
3. Enter the following command to start the emulator:
console com2

Important Notes

Restarting the server or the operating system does not terminate the SSH connection.

You cannot connect to the iDRAC of the system onto which you are currently logged in.

When connected, use the following key mappings for non‐character commands:
• <ESC><0> for F10
• <ESC><!> for F11
• <ESC><@> for F12
• <ESC><R><ESC><r><ESC><R> for Ctrl‐Alt‐Del
