VERITAS not recognizing tape drives

Hello!

I inherited the following backup system:

VERITAS 5.1 running on a Windows 2003 Master/Media server. No other media servers are present. The tape library is a Quantum M2500 with 5 QUANTUM SDLT320 drives.

Background: Everything was running fine until several weeks ago. VERITAS reported one drive as down and would not "up" it, saying it was not available. I rebooted the server and then 2 more drives reported the same status. The OS was recognizing all the tape drives. I managed to restore 1 drive by deleting it from the VERITAS configuration and adding it back. All is fine with the drive.

The Problem: I can not get this to work with the other 2 drives. When I add the drives back, even though I specify QUANTUM SDLT320, the "Inquiry Information" field report ATTO. When I try to add the drives via the wizard, it sees the robot but reports it only has 3 drives. I have deinstalled and reinstalled the drivers for the tape drives and still VERITAS is not seeing them as QUANTUM.

Has anyone seen a problem like this? Any ideas?

On a possible related note, I ran the tpconfig command to get a listing of the drive configurations (this was when I lost just 1 drive). When I ran it again (after I lost the other two) I noticed that the drive path changed for one of the drives and duplicates one of the other. Strange?

Thanks for any help!
 
Sounds like a persistent binding issue, is this library and the drives on a SAN?
 
Nope. Not using SAN.

And Friday, things were backing up in the morning, and then before jobs finished, the remaining drives conked out on me. One by one they started giving me error 84 (media error). When I checked the logs, they were reporting I/O errors in tape reading before the drives were downed. So, now all drives are down, and on 2 of them I get the following when I try to up the drives:

Unable to up the selected drive.
The drive is not ready or inoperable (277)

This is how the other 2 drives started acting before VERITAS stopped seeing them altogether.
