dm_core_hw

[ajax13]

Root keeps getting a message from EMS, the message contains this info
Event Monitor Restart information:

Title: dm_core_hw
Command: /usr/sbin/stm/uut/bin/tools/monitor/dm_core_hw
Vendor: Hewlett-Packard Company
Version: B.01.00
Monitor PID: 9883

Is this something I should be worried about?
Looking at the syslog file I found this info

Apr 11 13:58:52 server_name EMS [1665]: ------ EMS Event Notification ------ Value: "CRITICAL (5)" for Resource: "/storage/events/disk_arrays/FC60/000600A0B8092F
9C" (Threshold: >= " 3")

What is causing this error? Apprecaite any help.

Thanks

If you are getting Event Restart notifications approximately every 15 mins, this a known problem with EMS. To resolve load the following patch.

PHSS_23332 - s700_800 11.00 Support Tool Manager Patch

It has a dependency of PHCO_22628

The patch text for PHSS_23332 describes the fixed defect.

Are you getting restart notifications every 15 mins?

Hope this helps.

Samir,

What is the detailed error message from the FC60? You can find it in /var/opt/resmon/log/event.log. It might be a hardware or a configuration issue.

Thanks everybody,

Looking at the note for patch PHSS_23332, this maybe the answer, I have PHCO_22628 installed, but to apply this patch looks like I need to reboot the machine, so I may have to do this over a weekend.

I am getting a message every 15 mins or less.

I found nothing related to FC60 in the event.log.

But when I issue a command that mensioned in syslog file, I get this message.

The patch may make this issue go away for you. Patch PHSS_22847 resolves a few things.

1) new FC60 firmware HP06 and disk_em report false event #30 messages.

2) dm_core_hw restart notifications

This patch has been superseded by PHSS_23332. Neither this patch or the dependant patch requires a reboot.

hope this does it for you.
