Unknown Dg appears in Disk Groups with some or all disks
Hello,
Since support from Symantec is slow (not every case, but this time), I am asking this on forum.
I am doing a new installation and suddenly I have this new DG called "Unknown Dg". There a...
So I worked on this with Symantec support. We tried vxtool but with no avail, because we got mesages saying that disc is not usable !
but after I managed to have all disks back. What I did is:
- installed all recommended Windows fixes (2 recommendation from qlogic - HBA manufacturer, 2 recommendation from IBM manufacturer of SDD DSM)
- updated driver of HBA - STOR Miniport (to recommended level)
- updated firmware, bios, fcode and EFI of Qlogic HBA (everything is in one download package - I did it via Sansurfer FC HBA GUI Manager)
- installed Subsystem Device Driver DSM Version 2.4.2.1-2 from IBM
- configured all two HBAs from Sansurfer FC HBA GUI Manager
this helped me to get back all disks, but one - quorum disk was still missing in VEA
so removed both cluster nodes from cluster with command "cluster node /forcecleanup"
and than when I did a rescan, I was able to import Disc group with no missing discs. Then I destroyed all disc groups (except BasicDG with boot disc). And I am going to configure this cluster again.
So I think, that problem was because the servers were part of MSCS cluster.
But first I will create a quorum disc group and then create MSCS cluster. I hope it will work out this way.
I will let you know about the outcome.
