Need help with VMS Cluster ... Memory Dump

Hi there

I have one Alpha ES45 and one ES40 connected through MemoryChannel, directly without a hub. I installed OpenVMS 7.3 on both machines (new installation). Everything works fine until the cluster is activated by Cluster_Config. After the reboot one system starts up and the later one (no matter which one) starts and crashes with a memory dump. This occurrs after joining the cluster.... starting disk serving... error mounting system device.... reset and dump.

I have not defined a quorum disk and there is no shared storage attached. Just the two systems with one disk each and the MC connection.

I think this should work ...?

I have not much experience with Alpha clusters but I set up some VAX clusters some years ago and this was never a problem.

Maybe I have to disable disk serving?

Re: Need help with VMS Cluster ... Memory Dump

christian ,

can't remember the commands now at the >>> prompt, but each of the memory channel devices will default to mc0
if memory serves , have you changed one to be mc1 or above ?

Re: Need help with VMS Cluster ... Memory Dump

Christian,

you are using 2 separate system disks, right ? Did you make the volume labels unique in the cluster or do both system disks have the SAME volume label ? That would explain a PROCGONE crash. early during boot of the 2nd node.

What kind of crash are you seeing ? Just provide the bugcheck message from the console output first.

Do you get this message

exit %X7280B4
%MOUNT-F-VOLALRMNT, another volume of same label already mounted

Christian,

I think Voler and Gerard (Labadie) hit the right issue.

You wrote

<<<

In that case, without special extra action, both system disks will have the same label.
Which can not be in a cluster...
After the first node is up, do
$ SET VOLUME SYS$SYSDEVICE/LABEL=
Then REBOOT that node, and boot the cluster.
I would expect that (at least THIS) problem will not show again.

hth

Proost.

Have one on me.

Re: Need help with VMS Cluster ... Memory Dump

I had the same label on both system disks but I already changed one and it did not help. But to be sure, I will reinstall the system with a different label from the beginning.

regarding licenses... I really don't know, do Alpha-VMS cluster licenses exist or are they integrated to the VMS system license?
