After adding new TEMP license keys, media servers are showing offline.
The same may happen too when Netbackup on affected media server was shutdown, before performing system/SAN changes or maintenance on the media server. Media server is not active for tape devices.
Media server showing offline
Media server not showing "Active for Tape and Disk"
Multiple potential causes.
Run the nbemmcmd command to update the host's machine state, which is located in the following path:
Unix: /usr/openv/netbackup/bin/admincmd/
Windows: install_path\NetBackup\bin\admincmd\
Note: Sometimes the above may not work because connection is still not established between PBX.
Then, refresh the NetBackup Administration Console and the media server status will be back to previous state.
