tape drive dropping offline in the middle of a job
The issue we’re seeing is as follows: Backup Exec 2010 R3 SP2: We have a Tandberg Storage Library T24 with two HP LTO5 drives in it. It’s attached by fiber to the Q-Logic 8Gb FC Dual-port HBA. We have 2 backup jobs that run nightly. One goes directly to tape and the other goes to disk and then to tape. Tandberg has swapped out both tape drives and the tape library. We’ve tried different fiber cables and now we’ve swapped out the Q-Logic card. One of the tape drives drops offline in the middle of the disk-to-tape portion of the job. I am unable to find WHY it drops anywhere. I’ve verified the SCSI configuration and I do not see any problems. I’m not seeing the tell-tale Event ID 9 or 11 that would suggest a problem.
If I restart BE services, I can rerun the duplicate to tape job fine, but it fails again at it's next scheduled run.
I'm about to pull my hair out! Any help would be greatly appreciated.
