Re: OpenVMS Cluster crash
$ ANAL/ERR/ELV TRANSLATE/INCL=BUGCHECK/SINCE=...
Does SYS$SYSTEM:SYS$ERRLOG.DMP exist and is it big enough ?

Re: OpenVMS Cluster crash
As there's little evidence here of what transpired; if no dump and no error logs and no controller logs... Or even if so...
Set up logging to capture these events as described elsewhere and also capture via the console serial lines.
Ensure both boxes are set to RESTART/REBOOT, and not to HALT, nor to REBOOT -- this via the SRM console AUTO_ACTION variable.
Patch to current. For on the hosts and controllers.
I'd be seriously tempted to tie the MSAs into the logging, as well as the UPS.
Move down the racks, and up-rate the monitoring on and the UPS and related configurations of the other boxes in a similar fashion. Rack-mount boxes have a nasty habit of incurring unintentional and incremental changes, and this can lead to network switches that aren't covered by UPS, storage controllers that aren't, or any number of other subtle "adjustments" to the intended configuration.
Then wait for the next one.

Re: OpenVMS Cluster crash
SYS$MANAGER:OPERATOR.LOG would show entries like this:
_BUCL02$OPA0:, BUCL02 shutdown was requested by the operator.
It doesn't
DIAG/SIN.. would show entries like this:
Entry Type 65. Volume Dismount
SWI Minor class 5. Volume dismount
It doesn't
Volker,
AUTO_ACTION is RESTART
Will ANAL/ERR/ELV..... give me more information than DIAG.... does?
I don't think so and DIAG shows a time stamp entry at 23:50 and configuration informations at 23:58.

Re: OpenVMS Cluster crash
then these 2 OpenVMS system really did not 'crash'. They may just have 'booted' without a prior crash. And this most likely can only caused by a hardware event/signal. Look for something similar to those 2 machines, which could have affected both machines at the same time.
Only console information would have been able to provide more info, if there was really anything to tell. If you see just an INIT message on a console of a running system, you still have to wonder about the underlying reason.
Another piece of info to check would be the configuration entries logged at boot time. Maybe there are some status bits, which would tell more about the preceeding events...
Volker.

Re: OpenVMS Cluster crash
We will try to capture as much information as possible (console logging, msa1000 logging,...)
and wait for the next time as Hoff wrote.
We haven't seen something like this for the last 6 years, so there is a chance to survive the next decade without seeing it again.

Re: OpenVMS Cluster crash
Do you have any CLUE listing files in SYS$ERRORLOG: ?
These should get written at system boot time.

Re: OpenVMS Cluster crash
there are only some old CLUE$node_date_time.LIS files. They don't help.
CLUE$HISTORY.DAT does not contain any information related to the problem.

Re: OpenVMS Cluster crash
While you are checking things, please carefully check the grounding of the systems, in addition to the power.
Grounding problems can cause all manner of failures, many of them seemingly mysterious. A grounding failure can be something as simple as a corroded connection.
