9.5 Replacing Server Components

This section explains how to replace server components.

Replacing a network interface
The procedure used to replace a network interface is the same as that described in "9.4 Replacing Servers".
Refer to "9.4 Replacing Servers" for details.
If the target server is running Red Hat Enterprise Linux 5 or Citrix XenServer, log in with administrative privileges on the server and run the following command (this should be performed after completing the steps described in "9.4 Replacing Servers").
# /usr/local/sbin/macbindconfig update <RETURN>
[Xen]
When using Citrix XenServer, login from the console and run the following command. After running the command, reinstall XenServer referring to the manual for Citrix XenServer.
# /usr/local/sbin/macbindconfig update <RETURN>
When using Red Hat Enterprise Linux 5 Virtualization (Xen-Based), perform the following procedure.
1. Execute the following command to temporally disable automatic startup of the xend daemon then restart the managed server.
  # chkconfig xend off <RETURN>
2. Once the server has restarted, execute the following commands to update MAC address bindings, re-enable automatic startup of the xend daemon, and restart the xend daemon itself.
  # /usr/local/sbin/macbindconfig update <RETURN>
  # chkconfig xend on <RETURN>
  # service xend start <RETURN>
Replacing an HBA
The procedure used to replace an HBA is the same as that described in "9.4 Replacing Servers".
Refer to "9.4 Replacing Servers" for details.
When using I/O virtualization, the replacement HBA will automatically inherit the WWN originally set on the replaced HBA. Therefore, there is no need to re-configure access paths on the storage side.
Replacing a boot disk (in local-boot environments)
Use the following procedure to replace a boot disk.
1. Replace the faulty boot disk with a new one.
2. If a backup of the original boot disk was taken, restore it to the new replacement disk.
Information
The backup and restore functions available in Resource Coordinator VE can be used to restore the boot disk contents.
Refer to "Chapter 8 Backup and Restore" for details.
Replacing other server components
No specific action is required in Resource Coordinator VE when replacing onboard server components like memory modules or other parts.
