Disabling on-demand unloads
The NetBackup EMM service may ask the resource broker (nbrb) to unload drives even though the media unload delay has not expired. This request is called an on-demand unload. If allocating resources for a request is not possible without unloading the drive, EMM may ask nbrb to unload the drive.
It may be helpful to disable on-demand unloads when a series of small related backup jobs are scheduled (such as multiple NetBackup database agent jobs).
To disable on-demand unloads
- Create the following file:
On UNIX
/usr/openv/netbackup/db/config/RB_DISABLE_REAL_UNLOADS_ON_DEMAND
On Windows
install_path\Veritas\NetBackup\db\config\RB_DISABLE_REAL_UNLOADS_ON _DEMAND
