If you type in vgdisplay -v it may help you detect which drives are causing the problem.

How to decode an lbolt error
=====================================================================
gbo390-d:~abramss/doc/11/lbolt.decode SDA 11/11/98
1. Get the "dev:" entry from the lbolt:
# dmesg | grep lbolt | grep dev:
SCSI: Abort -- lbolt: 18346341, dev: e7015000, io_id: 122e9a3
SCSI: Request Timeout -- lbolt: 18351441, dev: e7015000
SCSI: Abort -- lbolt: 18351441, dev: e7015000, io_id: 122e9be
SCSI: Request Timeout -- lbolt: 18356641, dev: e7015000
SCSI: Abort -- lbolt: 18356641, dev: e7015000, io_id: 122e9cf
SCSI: Request Timeout -- lbolt: 18362141, dev: e7015000
SCSI: Abort -- lbolt: 18362141, dev: e7015000, io_id: 122e9e0
SCSI: Request Timeout -- lbolt: 74105435, dev: 1f000000
SCSI: Abort Tag -- lbolt: 74105435, dev: 1f000000, io_id: 4ead34
Here we have two:
1f
e7
2. This is the major number of the device in question. Convert the first
two digits of the device from hex to decimal:
# printf "%#d\n" 0x1f
31
3. find out what driver this major number is. It tells us the type of
device:
# lsdev 31
Character Block Driver Class
188 31 sdisk disk
So, this is probably a disk !
4. Find the device file entry from the remainder of the lbolt error:
SCSI: Abort Tag -- lbolt: 74105435, dev: 1f000000, io_id: 4ead34
This is the minor number for the device that is failing.
a. Block device:
# ll -R /dev/ | grep 31 | grep 0x000000
brw-r----- 1 bin sys 31 0x000000 Jul 15 16:25 c0t0d0
Or:
b. Character Device:
# ll -R /dev/ | grep 188 | grep 0x000000
crw-r----- 1 bin sys 188 0x000000 Oct 11 07:15 c0t0d0
5. Find the Hardware Address:
# lssf /dev/dsk/c0t0d0
sdisk card instance 0 SCSI target 0 SCSI LUN 0 section 0
at address 0/0/0.0.0 /dev/dsk/c0t0d0
6. Find the type of device:
# diskinfo /dev/rdsk/c0t0d0# diskinfo /dev/rdsk/c0t0d0
SCSI describe of /dev/rdsk/c0t0d0:
vendor: DGC
product id: C2300WDR1
type: direct access
size: 4102875 Kbytes
bytes per sector: 512
So, we have a Nike disk at hardware address 0/0/0.0.0, device file
/dev/dsk/c0t0d0

Re: HP L1000 running HPUX 11.0 is crashing often -
Appears to me that you have two separate problems here:
1) Disk c2t2d0 is causing SCSI errors - I'd replace it at your earliest opportunity.
2) You're either losing power or you have a bad/flaky power monitor board. If you can verify that in fact you're not losing power, then I'd log a HW call w/HP as there are known issues w/early L-class power monitor boards that cause all sorts of "false" errors. There is also a possibility that the UPS itself is the root cause of this. Either way this one is the problem that is most likely to be causing the reboots.
HTH,
Jeff
