Hi everyone:
I'm having a problem that seems like a HW config problem, but it only
happens when I'm duplicating tapes. All of my backups run fine, then during
the day, sometime in my duplication process a drive will be downed.
Duplication will be stopped and xdevadm will have a request pending, saying
that a tape needed is in a downed drive. I can't trace the problem to a
specific tape, tape drive, drive slot on the robot, or specific images. It
doesn't happen consistently either. I might duplicate 100's of images and
then stop. I'll manually reset the drive and eject the tape and restart the
process and it'll run fine. Some times it'll go for days before it stops.
The resultant problems seems to be a SCSI unload failure. I've swapped the
cables, drive order, and SCSI id's and it never fixes it. It seems to be a
HW problems but it only comes when I'm doing duplication, never with
anything else.
I've included a snap from my syslog of the error.
Any help would be really appreciated.
Thanks
