This section explains 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.
Place the reference server into maintenance mode
Be sure to stop all applications on the target server before continuing. In the RC console server resource tree, right-click the target server (or physical OS or VM host) to place into maintenance mode, and select [Maintenance Mode]-[Set] from the popup menu.
For details on the maintenance mode, refer to "Appendix F Maintenance Mode" of the "ServerView Resource Coordinator VE Setup Guide".
Perform software maintenance
Perform the necessary software maintenance tasks (such as patch application, or 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.
For details on collecting cloning images, refer to "8.2 Collecting a Cloning Image" of the "ServerView Resource Coordinator VE Setup Guide".
Release the reference server from maintenance mode
After collecting the cloning image, release the managed server from maintenance mode.
In the RC console server resource tree, right-click the server (or physical OS or VM host on the server) to be released from maintenance mode, and select [Maintenance Mode]-[Release] from the popup menu.
For details on the maintenance mode, refer to "Appendix F Maintenance Mode" of the "ServerView Resource Coordinator VE Setup Guide".
Deploy the cloning image
Propagate the changes made during maintenance by deploying the cloning image collected in step 4. to the remaining target servers.
For details on how to deploy cloning images, refer to "8.3 Deploying a Cloning Image" in the "ServerView Resource Coordinator VE Setup Guide".
