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 7.1 Software Maintenance Procedure Using Cloning
Each of these steps is explained below.
Place the Server into Maintenance Mode
Stop all applications on the target server.
In the ROR console server resource tree, right-click the target server (or its physical OS or VM host) and select [Maintenance Mode]-[Set] from the popup menu.
For details on the maintenance mode, refer to "Appendix C Maintenance Mode" in the "User's Guide VE".
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 "17.2 Collecting" in the "User's Guide VE".
Release the Reference Server from Maintenance Mode
Release the managed server from maintenance mode.
In the ROR 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 C Maintenance Mode" in the "User's Guide VE".
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 "17.3 Deploying" in the "User's Guide VE".
