Thanks everybody for all the useful suggestions. I haven't really played
much with disk staging yet. These 84s were basically due to not staging to
tape correctly, but they got me to thinking how I can use all the available
space efficiently, i.e. without backups failing until it had run out of
space across the board. I didn't really want to get into multiple storage
units (or groups) but it sounds like this will be the way forward for now.
cheers, Phil

I've not been able to get the 2 to work together in a STU group.
What patch level of NBU are you running?
What kind of *scrape* schedule are you running at the back end of the
DSSU? Are you not running it often enough causing it to fail with 84
errors? Are you using all your tape drives in regular STUs and when the
DSSU goes to offload images, there are no tape drives available for use?
I've gotten 84 errors on DSSU when that is the case. There is a doc out
on the Veritas site that discusses cleaning images from DSSU.

NBU5.1
Master : Sun v880 Solaris 9.
3*Media : Sun v880 Solaris 9.
EMC Clariion Cx300.
Can disk storage units / disk staging storage units be configured to
work usefully in a storage unit group?
I have 3 media servers each with a disk staging area. I would like for
backups to go to one, then if full, go to a different one. The way
things stand at the moment, if the disk staging area fills up on the
first server, backups continue to go to it and all fail with 84. The
equivalent would work with tape drives.
Ideally, thinking about it, I'd like backups to go to all three staging
areas in parallel, but I can't think how to achieve this.
Disks / Staging areas / SSO is new ground for me so if the answer's
"RTFM" then I'll go and do so :-)
thanks, Phil
