In our experience :
DSSUs don't work in Storage Unit Groups at NBU 5.1 as NBU isn't clever
enough to handle one unit being full and move onto another. Having said
that, it shouldn't fail jobs when the DSSU is 100% full unless it hasn't
found any old images which can be expired from disk (because they are on
tape). So it sounds like maybe there is a problem with your staging
jobs.
I have had problems with staging jobs where there has been some kind of
I/O error on the disk unit, which has caused the staging job to fail,
but NBU has not recovered the job nor cancelled it, so another job never
started (and the error wasn't picked up).
I understand disk staging to be much improved in 6.5.1 & so am hopeing
to get upgraded in the next month or so.
cheers, Phil

Subject: [Veritas-bu] Backups only writing to one storage unit group
member
I'm on netbackup 5.1 mp4 on solaris.
I set up some storage unit groups using disk staging storage units
(dssus). Backups that point to these groups are only writing to the
first member in the storage unit group, there's nothing being written to
the second storage unit.
The first storage unit is 100% full as a bunch of staging jobs haven't
completed yet, but at least one backup so far has failed due to no
space, even though the second member of the storage unit group is
sitting there with plenty of space.
After I created the storage unit groups I bounced the daemons.
What am I missing here?
