Here's the general process I think I would follow. First, stop directing any backups to DSSU until your "maintenance" is done. Run bpimmedia to see which images are on your dssu (bpimmedia -disk_stu <stu label> For each of those images, run bpimagelist to see how many copies there are (bpimagelist -backupid <BID>) For those images which don't have a copy on tape, duplicate it (kick off your de-stage job) For those images that do have multiple copies, expire the dssu copy (bpexpdate -backupid <BID> -d 0 -copy <#>) Repeat those steps until you're sure you have all your data protected.
The bottom line though is to make sure that before you go deleting (expiring) anything, you've got the data protected. You don't want to accidentally erase an image that is ONLY on disk. -Tim On Mon, Jan 26, 2009 at 3:43 PM, Ed Wilts <ewi...@ewilts.org> wrote: > On Mon, Jan 26, 2009 at 3:24 PM, Matthew Stier < > matthew.st...@us.fujitsu.com> wrote: > >> Background: Solaris 10 master/media server with several filesystems >> mounted from SAN to act as DSSU's.
