The most painless way to accomplish this is to acquire a temporary Media Agent license if you do not have an extra available Media Agent license and either a shared library license or extra library license to complete the install/migration.
For the purpose of this email I am going to refer to the original CommServe/Media agent as machine [CommserveA] the target install media agent [MediaAgentB] and the rename of the media agent as [MediaAgentB_OLD]
Contact your sales team for the CSID change license.
Run a DRbackup before any configuration changes!
Log into the CommCell Console on [CommserveA]
- Verify that all storage policy copy sets are pointed to [MediaAgentB]
- Verify there are no libraries or storage policies configured to media agent [CommserveA]
- Rename media agent [MediaAgentB] in the CommCell console GUI to [MediaAgentB_OLD]
- Perform a Disaster recovery backup on [CommserveA] and save this backup in a safe location.
- On [MediaAgentB] preserve the index cache (not necessary) by locating the index cache and saving to a temp directory
- On [MediaAgentB] uninstall the Media agent software.
- Perform a fresh install of the 8.0 Commserve software first only (do not install any other platforms at this time).
- Restore the Disaster recovery backup using the DR restore GUI in the CommVault base directory. (You can refer to the commserve rebuild guide for step by step instructions and screen shots)
10. Using DR restore GUI Perform name change operation (this will change the database name from [CommserveA] to [MediaAgentB]
11. Apply CSID change license you receive from the sales team.
12. Install the media agent software.
13. Copy the index cache into the location specified during the install of media agent [MediaAgentB]
14. Apply the latest service pack.
15. Next configure the library and drives on media agent [MediaAgentB]
- Launch the Library and drive config tool from the control panel.
- Select the new Media Agent [MediaAgentB]
- Select Start and detect and configure the library and drives
- Exit Library and Drive Config tool.
16. From the CommCell browser. Expand Storage resources ' MediaAgents select media agent [MediaAgentB_OLD] select the tape old library and right click and "Mark all media exported." This is necessary to let the DB know that the tapes are no longer in that library, before we perform migrations.
17. Once the media has been marked exported, we must change data path for each storage policy copyset, for every storage policy associated with the old MediaAgent [MediaAgentB_OLD]. In order to perform this task, review each storage policy and see which copysets are used by the old media agent.
- Expand Policies ' Storage Policies
- Select all tasks change datapath.
- The list of tapes will come up, select ok. It will ask which library to migrate to.
- Select the library on the new MediaAgent [MediaAgentB] and the appropriate Drive Pool and Scratch Pool, select ok.
18. This will migrate the media for the copy set from the old MediaAgent [MediaAgentB_OLD] to the new MediaAgent [MediaAgentB].
19. If there are also magnetic libraries configured on [MediaAgentB_OLD] they also need to be logically migrated from [MediaAgentB_OLD] to [MediaAgentB] To do so, on the magnetic library, right click and select migrate magnetic library. On the drop down menu, select the [MediaAgentB]
20. Once everything has been migrated, the new Media Agent [MediaAgentB] will be setup successfully.
21. Now, you can delete the old Media Agent [MediaAgentB _OLD].
- Launch the Library and Drive Config Tool from the Control Panel
- Select the old Media Agent [MediaAgentB _OLD] and Deconfigure all drives and libraries associated with old Media Agent. Once deconfigured, delete them.
- Exit the Library and Drive Config Tool
22. From the CommCell Browser right click on the old Media Agent [MediaAgentB _OLD] and select Deconfigure. Once deconfigured, right click and delete.
