EMS (bogus) error - Clariion EMC array

Hello HP community,

We seem to have a somewhat mysterious matter on our hands...a few months ago, we started to get logged events in syslog.log that ressembled this:

Aug 28 01:33:17 aph092 EMS [4168]: ------ EMS Event Notification ------ Value: "SERIOUS (4)" for Resource: "/storage/events/disks/default/0_6_2_0.32.16.0.0.0.6" (Threshold: >= " 3") Execute the following command to obtain event details: /opt/resmon/bin/resdata -R 273154138 -r /storage/events/disks/default/0_6_2_0.32.16.0.0.0.6 -n 273159025 -a

So we ran the command as stated, the output was:

root @ aph092:HP-UX/11.11[/var/adm/syslog]
# /opt/resmon/bin/resdata -R 273154138 -r /storage/events/disks/default/0_6_2_0.32.16.0.0.0.6 -n 273159025 -a

Summary:
Disk at hardware path 0/6/2/0.32.16.0.0.0.6 : Software configuration error


Description of Error:

The device was unsuccessful in processing the current request message
because the message contained an invalid field in the command data block.
The request was not processed.

Probable Cause / Recommended Action:

The error most likely indicates that the device is not fully supported by
the current driver. This may or may not cause a problem in the operation
of the device.

So in essence, we are out of options as to determine why this one drive generates these errors while no other in that array (RAID5) displays the same symptoms ?

Any leads will be appreciated.

Best regards to all,
Serge

Hi,

issue

# cstm

cstm>map

Do you have Unknown under column Product and on lines of EMC disks?

Best regards,
Fabio
WISH? IMPROVEMENT!

Re: EMS (bogus) error - Clariion EMC array

I've seen this often with Clariion arrays attached to HP-UX.

See this thread:

What are the chances...

Re: EMS (bogus) error - Clariion EMC array

Joshua,

Read that link, and it directed me in the right direction...since the SAN boys here are at a lost as to why this monitored event keeps cropping up, we decided to take out of OS monitoring, since they do their own monitoring on the SAN anyways.

Points awarded to all,
Thanks very much to all.

Re: EMS (bogus) error - Clariion EMC array

As per my last post, we took out the monitoring key for that specific device, and will let the SAN boys keep an eye on it from their side.

Points have been awarded to all who participated.

Thanks again,
Cheers, Serge
