What version of NBU and OS platform?  
 
We have similar issues with NBU 6 MP3 on Win.  Almost like there is some
sort of limit saying only 1 drive per job no matter how many streams.
We have 4 9840 drives all with SSO between 2 servers.  One of which is
in the process of being physically moved and is not even connected to
the drives at the moment.  Even our DSSU off loads during the day only
use one drive per DSSU with no other jobs running.

Subject: [Veritas-bu] Not Using all Tape Drives


I've begun monitoring tape drive usage, and comparing it to 'bpdbjobs
-summary' output every X minutes.  I've found that we consistently have
at least a quarter of our drives empty, even during our busiest times,
with many backup jobs queued.  How can I determine why these drives are
not getting used? 
 
Thanks in advance
