The admin server can be recovered even when resources on the server are damaged by operator error, provided that the resources managed by Resource Coordinator VE were backed up beforehand.
It is recommended that you create a backup once a system has been set up under Resource Coordinator VE, and after the registration, modification, or deletion of resources.
The resource files managed by Resource Coordinator VE are:
Resource Coordinator VE's environment definition files (files under the installation folder)
System images and cloning images (files under the image file storage folder)
Back up Resource Coordinator VE resources on the admin server using the following procedure:
Back up authentication resources
Back up system images and cloning images
Export the system configuration file
Restore Resource Coordinator VE resources to the admin server using the following procedure:
Reinstall the manager and restore authentication resources
Restore system images and cloning images
Import the system configuration file
Information
Recovery can also be performed by first backing up the entire admin server disk, then restoring it.
In a clustered manager configuration, the disk shared between cluster nodes should also be backed up and restored.
However, take note of the following:
Do not perform a backup or restore of the admin server while server switchover or failback is taking place, or while a system image is being backed up or restored.
After a backup, restore is only possible if the settings and configuration of the following hardware devices has not been changed.
Replacement of a chassis, LAN switch, managed server, power monitoring device hardware
Replacement of a managed server NIC
LAN connection between managed servers and LAN switches
Server switchover or takeover (*1)
*1: If failback has been performed after server switchover, restore can be performed.
In addition, when backing up Resource Coordinator VE resources on the admin server after backing up the entire admin server disk, first restore the entire admin server disk, then restore those resources and import the system configuration file following the instructions given in step 2 and step 3 of "B.3 Restore".
