Hi,
Well it is clearily says that the issue is with your driver.so insert the driver for disk again in the kernel and reboot the system.

hi,

looks like you have emc clariion CX attach to your server.

I don't think driver patch is an issue if other HP disks are well detected.

or maybe this 0/0/4/1/0.117.2.239.0.0.1 is actually the storage controller.
You can check this with emc vendor is this normal.

U can also check if this lun were remove previously from navisphere. If that is the case, the only thing you can do to stop EMS from reporting this is to `rmsf` this disk device.

Let us know.

Hi Joelmel

Can you look at following URL.
http://www12.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=ucr_na-KMN8606469959_ssb-1

You are using EMC disks but the device path in your log looks like similar paths in the document

You can upgrade OnlineDiag from following url
http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=B6191AAE

HP-UX 11i v2 (11.23) (March 08 release)
B.11.23.11.05, STM version: C.60.00

Hi Joelmel,

I am having solution::

Run the cstm on the comamnd propmt
# cstm
cstm> dsd
Select Deamon to Shut Down on the host
1 diaglogd
2 memlogd
3 psmctd
Enter selection or cancel to quit : 3 >>> Here we need to Shutdown psmctd daemon. Hence choose the appropriate number
Are you sure you want to shutdown psmctd?
Enter Cancel, Help, or OK: [Cancel] OK
cstm>
cstm> quit
Enter Cancel, Help, or OK: [OK] OK
#
# cd /var/stm/data
# pwd
/var/stm/data
# mv psm_data /tmp
Move the following file for precaution !!
==> Run the cstm again from the command prompt:
# cstm
cstm> dsu
Select Daemon to Start on the host
1 cclogd
2 psmctd
Enter selection or cancel to quit [done]: 2 >>> ( start the psmctd daemon. Hence choose the appropriate number)
Enter selection or cancel to quit [done]: Press Enter
cstm> quit
#

Also restart diagnostic daemon

# /sbin/init.d/diagnostic stop
# /sbin/init.d/diagnostic start

Cheers,
SHR
