panic cpu:0

[Joris Denayer]

OK,

I have to apoligize.
The mistery is solved. It's my fault.
This _panic_message changed with the installation of PatchKit #5.
Sorry for wasting entries

From Patchkit #5 onwards, the message changed to
"NULL fifo_bufhdr append pointer"

Hi Enrique,

how many members has your cluster? Have you had any troubles with the quorum disk lately?

greetings,

Michael

Hi Enrique,

you find this quite often in the crash file. I wonder, if the memory channel is damaged.

regards

Michael

Enrique,

~30 seconds before the crash, the other member went offline.
There are some known issues with clustermembers crashing, when an other member shutdown or powerdown.
Most of these issues are fixed in the patchkits.
Indeed, as Michael said, problems with the cluster interconnect will not help to make a cluster stable. Everything should be correct in terms of cabling, firwmware version, strapsetting, etc..
However, seen the uptime of the system, I believe more in a software problem.

Therefore, I should plan
1) the installation of the latest patchkit (kit#6)
or even better
2)an upgrade to v5.1B

This is only a free advise. If you want to know what happened exactly with your system and you have a valid contract then you can open a case at HP Services.

Enrique,

The version of fifo_vnops.c is not the version delivered with patchkit#6.
I see that you installed patchkit #6, but it must have been installed only partially.
The vfs.mod which contains fifo_vnops.c is part of OSF510-1163
This is one of the most important patches (patch 1163). A lot of other patches depend on the installation of this one.
As it is not present in the patchlist, it must have been rejected during the run of dupatch.

I propose to run a dupatch baseline. This will give the reason why it is not installed.
