Getting lbolt errors. Which device is this?

Ray Humpage — Tue, 15 Apr 2008 17:17:40 GMT

I had a disk go bad. I removed it from the LV mirror. Still getting these messsages. Trying to determine if I have another disk failing.

My guess..(only because I cannot remember off the top of my head). Check device with diag ( xstm > info ).

/dev/dsk/c6t1d0

b_dev: cb061000 is the line that gives it to you.

seach this forum using keyword lbolt. There are 100s of replies to this issue.

Hi Ray:

Device cb061000

0xcb = 203 --> ctl [from 'lsdev']
0x06 = 6 --> bus number
0x1 = 1 --> target
0x0 = 0 --> lun
0x00 --> flags

Regards!

I seemed to me it would be /dev/c6t1d0 also.

I don't have a disk device named that when I do an ioscan? Just a tape device which has no tape currently in it and no process running against it.

nmhptprd(/var/adm/syslog)# ioscan -fun|grep c6
/dev/rmt/1m /dev/rmt/c6t1d0BEST
/dev/rmt/1mb /dev/rmt/c6t1d0BESTb
/dev/rmt/1mn /dev/rmt/c6t1d0BESTn
/dev/rmt/1mnb /dev/rmt/c6t1d0BESTnb
/dev/dsk/c6t2d0 /dev/rdsk/c6t2d0
/dev/rscsi/c6t7d0

could you post an ioscan -fn please. Seems that the system things there is scsi ID 1 out there somewhere and hence the lbolt errors.

Check that all your SCSI cable connectors are properly plugged in. A loose connector or a bad cable may well cause lbolt errors.

If the bad disk is still physically present on the SCSI bus, some failure modes of the disk electronics may have an impact on the SCSI bus.

in syslog

for example if033000
once u found it
do
#ll /dev/*dsk | grep 033000

this will give to find the disk for further investigation
please revert it
