This section details the procedure to follow when replacing servers.
Information
Follow the same procedure when replacing servers where VM hosts are running.
No specific action is required in Resource Orchestrator when replacing admin servers or HBA address rename setup service servers.
Replacing a Server with Spare Servers Assigned
Use the following procedure to switch applications over to a spare server and replace a server with minimal interruption.
Perform Server Switchover
Switch over the server to replace with its spare server.
For server switchover, refer to "Chapter 4 Server Switchover" in the "Operation Guide VE".
After the server has been switched over, its maintenance LED is automatically activated, and the server is powered down.
Replace the Server
Replace the server whose maintenance LED is activated.
Change the BIOS settings of the replacement server to match the operating environment.
For details on BIOS settings, refer to "8.2 Configuring the Server Environment" in the "Design Guide CE".
Shut down the server after completing BIOS settings.
Reconfigure Hardware Properties after Replacement
After replacing the server, reconfigure Resource Orchestrator with the latest hardware properties.
For details on how to reconfigure hardware properties, refer to "9.2.2 Reconfiguration of Hardware Properties".
After hardware properties have been reconfigured, the maintenance LED is automatically turned off in the ROR console.
Perform Post-server Switchover Operations
For details on the operations that must be performed after server switchover, refer to "4.3 Post-Switchover Operations" in the "Operation Guide VE".
Replacing a Server with no Spare Server Assigned
Use the following procedure to smoothly replace a server and resume its applications.
Place the Server into Maintenance Mode
Place the primary server to replace into maintenance mode.
For details on maintenance mode, refer to "Appendix C Maintenance Mode" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".
Place the Server into VM Maintenance Mode
When the primary server is a VM host, and can be placed into VM maintenance mode, place it into VM maintenance mode.
For details on VM maintenance mode, refer to "15.2 VM Maintenance Mode of VM Hosts" in the "User's Guide VE".
Create a System Image Backup
For local boot servers, create a system image backup when possible.
For details on backing up system images, refer to "Chapter 16 Backup and Restore" in the "User's Guide VE".
In SAN boot environments, the boot disk can be restored without having to back up and restore a system image.
Activate the Maintenance LED
Activate the maintenance LED on the server that is to be replaced before shutting it down.
For details on how to activate maintenance LEDs, refer to "9.2.1 Maintenance LED".
Replace the Server
Replace the server whose maintenance LED is activated.
Change the BIOS settings of the replacement server to match the operating environment.
For details on BIOS settings, refer to "8.2 Configuring the Server Environment" in the "Design Guide CE".
Shut down the server after completing BIOS settings.
Reconfigure Hardware Properties after Replacement
After replacing the server, reconfigure Resource Orchestrator with the latest hardware properties.
For details on how to reconfigure hardware properties, refer to "9.2.2 Reconfiguration of Hardware Properties".
After hardware properties have been reconfigured, the maintenance LED is automatically turned off in the ROR console.
Restore the Boot Disk
Local Boot
There is no need to restore the boot disk if the original disk is installed on the replaced server. Simply power on the replacement server.
If the boot disk was replaced and a system image backup was collected, restore that backup.
When the image operation target disk is configured, configure the image operation target disk before performing restoration.
For details, refer to "9.1.13 Changing Target Disks of Image Operations" in the "User's Guide VE".
Refer to "16.3 Restore" in the "User's Guide VE" for details on how to restore a system image. After the system image is restored, the server will be automatically powered on.
If there is no backup of the system image, run the installation program again.
SAN Boot
As the replaced server can be easily configured to access the original boot disk using HBA address rename there is no need to restore the boot disk. Simply power on the replacement server.
Release VM Maintenance Mode
When the primary server was placed into VM maintenance mode, release the replaced server from VM maintenance mode.
For details on VM maintenance mode, refer to "15.2 VM Maintenance Mode of VM Hosts" in the "User's Guide VE".
Release the Reference Server from Maintenance Mode
Release the replaced server from maintenance mode.
For details on maintenance mode, refer to "Appendix C Maintenance Mode" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".
Servers with no Agent Registered
Use the following procedure to replace servers on which no Resource Orchestrator agent was registered.
Activate the Maintenance LED
Activate the maintenance LED on the server that is to be replaced and shut down the server if it is still powered on.
For details on how to activate maintenance LEDs, refer to "9.2.1 Maintenance LED".
Replace the Server
Replace the server whose maintenance LED is activated.
Change the BIOS settings of the replacement server to match the operating environment.
For details on BIOS settings, refer to "8.2 Configuring the Server Environment" in the "Design Guide CE".
Shut down the server after completing BIOS settings.
Reconfigure Hardware Properties after Replacement
After replacing the server, reconfigure Resource Orchestrator with the latest hardware properties.
For details on how to reconfigure hardware properties, refer to "9.2.2 Reconfiguration of Hardware Properties".
After hardware properties have been reconfigured, the maintenance LED is automatically turned off in the ROR console.
