SCSI: Resetting SCSI -- lbolt: 535857474, bus: 4

SCSI: Reset detected -- lbolt: 535857474, bus: 4
LVM: PV 2 has been returned to vg[2].

[Georg Tresselt]

From the first line I would guess that you have a faulty device on SCSI bus 4 and from the last line that it is a hard disk connect to group vg[2].

[Cheryl Griffin]

Looking at "LVM: PV 2 has been returned to vg[2]." This means that the second physical disk in the second volume group may need to have it's timeout increased with pvchange -t 180.

How often are the SCSI bus hang messages occuring? What was happening at the time time of the errors? There are numerous causes for these messages.

[George_Dodds]

I've checked my records and the disks for vg02 are on our XP256 array.

Calling HP now to get them to check it out.

[Eric Antunes]

Hi George,

From my experience, each time I had those "lbolt" messages, I did replace the disk...

Best Regards,

Eric Antunes

You shouldn't receive scsi bus reset errors
for XP disks, they are Fibre connected.
Run ioscan -fn, find "ext_bus" instance number 4 and see what kind of device with scsi id 8 is there.
