This section describes how to perform maintenance operations on managed servers.
Maintenance operations should be performed first on one reference server before propagating changes to the remaining target servers.
Figure 11.1 Software maintenance procedure using cloning
Each of these steps is explained below.
Put the reference server into maintenance mode
Be sure to stop all applications on the target server before continuing.
In the RC console resource tree, right-click the target server (or physical OS or VM host) to put into maintenance mode, and select [Maintenance Mode]-[Set] from the popup menu.
Refer to "Appendix F Maintenance Mode" in the "ServerView Resource Coordinator VE Setup Guide" for details on maintenance mode.
Perform software maintenance
Perform the necessary software maintenance tasks (patch application, software addition or modification) on the reference server.
Check operation
After completion of maintenance tasks, confirm that the OS and applications still operate properly to validate the changes made during maintenance.
Collect the cloning image
Once all changes have been validated, collect a cloning image from the reference server.
Refer to "8.2 Collecting a Cloning Image" in the "ServerView Resource Coordinator VE Setup Guide" for details on how to collect cloning images.
Release the reference server from maintenance mode
In the RC console resource tree, right-click the server (or physical OS or VM host on the server) to be released from maintenance mode, and from the popup menu, select [Maintenance Mode]-[Release].
Refer to "Appendix F Maintenance Mode" in the "ServerView Resource Coordinator VE Setup Guide" for details on the maintenance mode.
Deploy the cloning image
Propagate the changes made during maintenance by deploying the cloning image collected in step 4. to the remaining target servers.
Refer to "8.3 Deploying a Cloning Image" in the "ServerView Resource Coordinator VE Setup Guide" for details on how to deploy cloning images.
