This can be done only via zoning or LUN masking.
NetBackup doesn't allow selecting particular drive paths for a storage
unit.
You can only specify the number of drives to be used for any given
server. 
You can however:
1) Direct critical backups on any of the 3 storage units you can create
with your current setup.
2) Play with number of drives to be used with 
        a) at the policy level
        b) storage unit group - will allow you to use more than one
storage unit if needed.

Cheers.

Subject: [Veritas-bu] Directing Backups to dedicated drives


Hi Forum,

I have a setup of netbackup 6.5.1 having 1 master server and 4 media
server with Storagetek SL500 Library having 16 drives.

1 media server is having robotic arm configured on it with 5 drives.
2 media server is having 5 drives.
3 media server is having 6 drives.

My requirement is of directing few critical backups to dedicated drives
only assigned for these backup.

Can anyone help me out in doing this in my backup environment.
