If the system was able to reboot after the crash, there should be a recent crash_data.x in /var/adm/crash/ then please post that here.
The posted output is not sufficient to determine a possible cause for the crash.

Re: TRU64-unix 5.1A cluster crashed

I see two different crashes there.
One (.9) is related to virtual memory handling and the other (.10)
does look like a issue with the aha_chim (SCSI-Adapter) - Driver.

I guess your next question is..."What can I do to avoid this ?"

There are two points that I would go for...

1-the crashed node is a AlphaServer DS25 running on Firmware: 6.8-18
the most recent Firmware is Version 7.3 ! See:
http://h18002.www1.hp.com/alphaserver/firmware/readmes/ds25.html
I would go for a update of the Firmware.
(Don't forget to check the other node for this too !)

2-if you have to stay on 5.1A, well...go and look if you have all
additional early release patches installed, if not get and install them.
http://h30097.www3.hp.com/unix/EarlyReleasePatch-download.html

Better would be a consideration if you can go/upgrade to 5.1B-5
but that is only my humble opinion.

Greetings,
--Uwe.
