Re: SCSI: First party detected bus hang -- which device?
I guess its my tape drive. Funny thing is, there wasn't any tape operation on the drive at all. From the dmesg what could have gone wrong?
I've been receiving these tape drive messages from some of my HP servers lately. Are there documentation for these messages? I would like to be able to decode these messages. Thanks

If you have h/w support, I'd place a call to resolve if none of these suggestions work.
I'm sure that the problem w/ the h/w is why you've seen the SCSI bus reset.
Good luck!

Re: SCSI: First party detected bus hang -- which device?
Under SAM there is an action called "Diagnose Missing Tape Drive". Will this cause SAM to redetect the DLT drive?

If you have found the tape drive was powered off or another issue, try ioscan after making the corrections. If the drive is avaialble, ioscan should pick it up as claimed.
