How to interpret SCSI error

Guys,

I've got following messages in syslog.log:

Mar 23 13:05:29 fwsk2 vmunix: SCSI: First party detected bus hang (HTH) -- lbolt: 22490461, dev: cb044002
Mar 23 13:05:29 fwsk2 vmunix:           lbp->state: 30008
Mar 23 13:05:29 fwsk2 vmunix:           lbp->offset: ffffffff

there are several key words above: HTH, lbolt, dev:and lbp. There are more terms that I have read about SCSI, and my question is: which guide would interpret all these terms about SCSI error or SCSI operation?

 

regards

Stephen

Re: How to interpret SCSI error

do you have a c4t4d0 tape or disk drive?  if so, you're going to want to take steps towards getting it replaced.

D.H.,

thank you for your reply.

in fact I knew how to deal with this case, hence I concern more about how to understand all these terms. like what is lbolt stands for.

it's really enough to know that you've got lbolts being reported.

[ Edited ]

Here is how you decode the device which gave this lbolt errror .
dev: cb044002 = dev: major :bus :target :lun :drivers specific flags

cb044002 decodes to
cb --> Major device 203
04 --> c4
4 --> t4
0 --> d0
02 --> driver specific.

so the device file is : c4t4d0

Hope it helps
