This appendix explains the maintenance mode available in Resource Coordinator VE and how to use it.
Maintenance mode is used during hardware maintenance of managed servers. It is also used during the installation and maintenance of physical OS's and VM hosts. Maintenance mode avoids unwanted error notifications and disables execution of Auto-Recovery upon server failure.
The following operations can be performed on a server that has been placed into maintenance mode:
Maintenance LED
Maintenance LEDs can be controlled.
Backup and restore
System images can be backed up and restored.
Cloning
Cloning images can be collected and distributed.
Use the following procedures to set and release maintenance mode:
Setting maintenance mode
In the RC console resource tree, right-click the server (or the physical OS or VM host on the server) to place into maintenance mode, and select [Maintenance Mode]-[Set] from the popup menu.
Releasing maintenance mode
In the RC console resource tree, right-click the server (or the physical OS or VM host on the server) to place into active mode, and select [Maintenance Mode]-[Release] from the popup menu.
Note
When using ServerView Deployment Manager, some operations may temporarily restart or shut down servers, thus affecting the statuses of those servers in Resource Coordinator VE.
It is recommended to place affected servers into maintenance mode before running operations from ServerView Deployment Manager. Then, the maintenance mode should be released once finished.
