Decommissioning and removing a media server from a NetBackup configuration requires several steps. If devices attached to the media server contain NetBackup media, move the media to a new media server. If the media is no longer usable or valid, delete it from the NetBackup configuration.
Use the following procedure to decommission a server (the <old_server>) and move the media to a new media server (the <new_server>). If this procedure is not performed and a subsequent restore requires media that is associated with the old media server, the media must be imported. Importing media consumes more time than the following procedure.
To decommission a media server
Note: All commands referenced below can be found in the following directories:
UNIX: /opt/openv/netbackup/bin/admincmd
Windows: <install_path>\VERITAS\NetBackup\bin\admincmd
1. Run the bpmedialist command to determine which tapes on <old_server> contain NetBackup images that have not expired. The -l option produces one line of output per tape.
bpmedialist -mlist -l -h <old_server>
2. Use the NetBackup Administration Console to move the tapes in the robots that are attached to <old_server> to non-robotic status (standalone). Select each robot that is attached to <old_server>. Select all of the tapes and move them to standalone (select Actions > Move).
3. Choose another server or the master server to manage the tapes from the decommissioned server. Logically move the media from <old_server> to <new_server>, as follows:
If both <old_server> and <new_server> are at NetBackup 6.0MP7 or later, or NetBackup 6.5.2 or later, run the following command:
bpmedia -movedb -allvolumes -oldserver <old_server> -newserver <new_server>
If <old_server> or <new_server> is at a version earlier than NetBackup 6.0MP7, or NetBackup 6.5.2, run the following command for each volume that has active images as identified in step 1:
bpmedia -movedb -ev media_ID -oldserver <old_server> -newserver <new_server>
4. Use the Administration Console to configure NetBackup so that restore requests are directed to <new_server>. In the General Server host properties of the master server, add a Media Host Override entry that specifies <old_server> for the Original backup server and <new_server> as the Restore server.
5. Use the NetBackup Administration Console (or the nbemmcmd -deletehost command) to delete the following:
Drives and robots from <old_server>.
All storage units that use the robots that are associated with <old_server>.
6. Modify any policies that specify the storage units on <old_server>. Change the policies to point to any other defined storage units in the NetBackup configuration or to Any Available.
7. Use the NetBackup Administration Console to remove any reference to the decommissioned media server in the Servers host properties of the master server. Also, remove references in the Servers host properties of all media servers and all clients. Restart the NetBackup daemons or services on any system that was updated.
8 Run nbemmcmd -listhosts to verify that all references have been removed.
9 If any robots from <old_server> are reused on other media servers, perform the following actions:
Shut down the affected servers and disconnect the robots from the old servers. Connect the robots to the new media servers. Verify that the operating systems on the new media servers recognize the robots.
Use the NetBackup Device Configuration Wizard to add the robots and drives to the media servers.
Use the NetBackup Administration Console to create the appropriate NetBackup storage units.
Use the NetBackup Administration Console to inventory the robots that are attached to <new_server>. The inventory updates the location of all tapes in these robots.
