Hardware traps seen in syslog

kaushikbr — Thu, 30 Nov 2006 04:46:26 GMT

Hi,

We have a Intel rx2620 based system running HP-UX B11.23. This morning we found that the telnet sessions to this machine was hanging for no apparent reason. We tried to connect from the ILO port, still we were not able to login. As a final resort we rebooted the box. After the reboot looking in the syslog file I found the following messages.

Nov 30 09:14:25 nuncas04 EMS [2655]: ------ EMS Event Notification ------ Value: "CRITICAL (5)" for Resource: "/ad
apters/events/raid_adapter/0_4_1_0_4_0" (Threshold: >= " 3") Execute the following command to obtain event d
etails: /opt/resmon/bin/resdata -R 173998082 -r /adapters/events/raid_adapter/0_4_1_0_4_0 -n 173998081 -a

This happens on a couple of other boxes as well not very often but sometimes and the only way to get around this problem is to reboot this box. I dont understand what the problem is. Is this a known problem ? Does this have any fix ?
I have copied the output of the resdata results.

Thanks in advance for all your suggestions.
Regards
Kaushik

Hi Kaushik,

This is not a error message, its a informative message and can be ignored. This error message can be viewed after every reboot. Though the issue is informative you can see the severity as CRITICAL.

Fix is made available in Dec of 2005 release of onlinediag product
located on OE media for HP-UX 11.23 release

Actual issue could be something else, would suggest you to register case with HP.

Best Regards,
Prashanth

Hi,
can you confirm that this controller controls the disk which holds either /, /usr or /home ?
When your controller does not work, your disks do not work and no login is possible.
The message just says the controller is on-line, but not why it went offline!
Are the problems always with the same controller/disks? If so I would replace it.

Hi Prasanth, Peter Thanks for your replies.

This controller is managing the MSA30 connected to the m/c. And the disks in the MSA30 are used only for the applications ( Oracle & TeMIP ).
All the / /usr directories are on disks driven by a different controller. The user home directories are NFS mounted.

However we have seen this happening on a couple of our machines even in the past.

Thanks and regards
Kaushik

Hi Kaushik,
I think that RAID event is a red-herring. As Prashant said, the severity level is incorrect in the version of OnlineDiags that you have and is corrected in the current, supported versions to be Informational. I would recommend upgrading the OnlineDiags, though I don't think that will address the underlying problem.

It sounds more likely to be a network related issue, or maybe the whole system locking up.

Also, when are those events being logged, before or after the system is rebooted? What was the last thing logged in syslog before the reboot?

Is anything working on the system when the telnet sessions stop? Is it just network connections failing, or is the whole system hung? Are there any I/O errors being logged (see logtool in STM)? What about the lights on the front panel, do they indicate any errors?
