Hi,
I have two windows 2008 R2 nodes within a cluster. Since a week one of the disk of the cluster became unavailable. The cluster logs show this : Cluster physical disk resource 'Disque du cluster 2' cannot be brought online because the associated disk could
not be found. The expected signature of the disk was 'E5888E77', but the disk signature is correct (E5888E77).
I can see the disk in the disks manager but I can't bring it online.
I read many topics about this problem but none help me to solve this issue. I tried to change the san policy to "onlineAll" but it doesn't help.I tried to make the disk online using the diskpart command but it doesn't work too.
Through the cluster resource commands I can see that the DiskuniqueIds is empty for the disk 2.
As read in another topic I have checked the following registry key HKLM\SYSTEM\CurrentControlSet\Services\Cludisk\Parameters\AttachedDisk
e5888e74 --> Disk 1 signature
{026061e9-eeb5-4354-bfd7-17d2cb77d2af}
e5888e77 --> Disk 2 signature
{026061e9-eeb5-4354-bfd7-17d2cb77d2af}
From what I read, the disk 2 should have a uniqueids value to be seen in the cluster right?
Thanks for your help
