Hello
I have configure Cluster DG with MS cluster.
On the share DG, I configure mirror volume that come from 2 storages. So in DG we have 2 plexes , 2 Disk (LUN).
When 1 of LUN failed (1 of storage failed), why the entire DG failed (offline)?
But I can manual import DG because 1 plex is still good.
Thank you.

Please see our DG configuration

Please post errors, there should be something in th event viewer. It could be because chkdsk is set to 1 and the volume was dirty.

Hi pgm10s,
The diskgroup should stay imported when it has lost upto 50% of the disks in the diskgroup. Since you mentioned that there are only 2 disks, I would think that there might be a different issue going on. I've seen issues where customers have expanded their volumes and the subdisks get placed on the wrong drive so that when 1 drive is lost there is only part of the subdisks for each plex available.Or there could be a log for the volume that is only on one drive and not the other. Can you provide a screenshot of VEA of the subdisks tab for the volumes in this diskgroup? I've attached a screenshot from one of my lab systems to give you an idea of what I would like to see.
As always, you can open a case with Symantec Technical Support if you need more direct or quicker resolution to your issue.
Thank you,
Wally
