DAT Library going offline v10

[Aaron_Lasnetske]

Win2003 Server, VBE ver10 Build 5484 w/ SP4 on Quantum (Certance) DAT-432 autoloader. Every week or so, apparently without pattern, I get the following error:

"Backup Exec cannot use this tape device because it has detected a mismatched tape device serial number. The device status has been changed to offline. Please restart all Backup Exec services to fix this problem."

And of course the backup job times-out and fails and future scheduled jobs will be "missed" until the drive is back online.

Usually stopping and restarting the BE services does the trick, but sometimes I have to reboot the server before the drive will come back online.

The only reference I've seen to this error on symantec/veritas site was a reference to a patch that "fixed" this error back in version 9.1.

Anyone have ideas?

Hello Aaron,
- Do you get any errors around the time?
- Any events in the event logs?
- Have you checked if your device is tested with Backupexec?
- Are latest Drivers installed?

Yes the Certance CDL432LWF-SS 6-tape DAT72 autoloader is on the HCL.

I've tried the latest Veritas drivers and drivers from Quantum (Certance) - doesn't seem to make any difference. The #58053 eventlookup links from the error messages returns silly stuff like "is your external drive turned on?" and "check the cable on your IDE drive". The most promising looking error above, #58066, returns "no documents match your search". That's not real helpful. And to make it even more fun - the problem is intermittant. Last night's backup worked perfectly. Everything exactly the same except which tapes were in the changer. And no, it's not the tapes, since they worked perfectly last Wednesday. It failed last Monday with the exact same errors, but worked this Monday. AARRRGGGHHH! If I could at least find a pattern I'd have somewhere to start.

Hello,

The errors ( 58066) may also occur due to SCSI Bus or tape device hardware issues.
Check the system and application logs for SCSI related events.

Aaron,

Were you able to resolve the drive offline issue? I am having exactly the same issue. The BE claims that the drive goes offline randomly. I mean it worked fine last Thursday, but Thursday this week it bailed out with the offline drive issue. We have a stand-alone drive.

I would appreciate if you could share any information.

Has this tape device been running normally before ?
Or are you getting these errors after having newly acquired the tape device?
