VMS Cluster Through MSA1000


OPS called the other morning (oh yes VERY early) to say that the scheduled reboot on one of the nodes resulted in the other node losing mount status on some of the shared disks.

The boot was a scheduled as a restart with no disk dismount requested. The other node is seeing the disks in mount verification state but it does not ever see the disks come back online (or so I'm told). We've seen this on the odd occasion in the past but found nothing indicating what is causing the situation. A reboot of the 'other' node fixes things.

OVMS 7.3-2, w/current patches.

Try performing a $Dismount/Abort and remount on the other nodes.

Re: VMS Cluster Through MSA1000

Can you describe your disk configuration on your cluster? Is it a shadowset?
When you reboot one member of cluster with cluster-mounted disks, you need correctly dismount these disks from node which is going to shutdown. Otherwise mount verification and disk-rbuild will start.

Re: VMS Cluster Through MSA1000

As part of your shutdown the disks should have been dismounted. Was there something that prevented this (open files, shutdown procedure not completing etc)?

Is there are log of the shutdown (if the ops connect to the console using a console management product then there could be)?
