Using Solstice Backup 5.1 on a Sun E3500 in conjunction with a Sun L1000 AutoChanger. Was running a full backup when the system crashed (8/4/01). System Administrator rebooted the box and everything came up just fine. Subsequent incremental backups (8/6, 8/7, 8/8, 8/9, 8/10) ran fine but the problem came about when the next full backup was fired off (8/11/01). Solstice wanted a tape from the "full" pool, it unloaded the incremental tape from 8/10 and loaded a tape from the "full" pool, which just happened to be the "full" tape that was in the drive when the system crashed on 8/4/01. Now we get error messages "Aug 11 13:11:08 carmichael root: Solstice Backup media: (warning) /dev/rmt/0mbn moving: fsf 203: I/O error". I've tried giving it another full tape but it won't take it. I've tried "inventoring" the autochanger but it won't let me. Can I just relabel the tape that is giving the I/O error? or should I take someother approach?
