How to interpret SCSI error

stephen peng — Wed, 28 Mar 2012 16:47:26 GMT

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

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.

regards

Stephen

(scroll to the bottom of the page)

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

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
