Following procedure can help cleaning corrupted globeDB.
1. Close the Netbackup console (Admin GUI)
2. On master server run the following
%installpath%\Volmgr\bin\vmglob -delete
3. On master server run-
%installpath%\Volmgr\bin\tpautoconf -upgrade
4. On each media server run-
%installpath%\Volmgr\bin\tpautoconf -upgrade
These steps will delete and then rebuild the global device database.
Before proceeding these steps, please make sure all the master server and media server can query Tape drives and get drive serial number. Run the following to verify:
%installpath%\Volmgr\bin\tpautoconf -t
This should list all the drive with theri serial number
Hope it might help. Have fun
