Dears,
I have SQL Server 2005 cluster, on two nodes that have Windows Server 2008 R2 Enterprise SP1, with 4 LUNSattached to the two nodes.
DTC (1 GB), quorum (1 GB), Data (250 GB) and LOG (100 GB). and it was working fine. but suddenly i found that Failover console shows that the four cluster disks are failed, although they are existed in the disk management of both nodes. and i try to bring any one of them online but i get an error:-
Cluster resource 'Cluster Disk 3' (resource type '', DLL 'clusres.dll') either crashed or deadlocked. The Resource Hosting Subsystem (RHS) process will now attempt to terminate, and the resource will be marked to run in a separate monitor.
Cluster physical disk resource 'Cluster Disk 1' cannot be brought online because the associated disk could not be found. The expected signature of the disk was 'DB4C0919'. If the disk was replaced or restored, in the Failover Cluster Manager snap-in, you can use the Repair function (in the properties sheet for the disk) to repair the new or restored disk. If the disk will not be replaced, delete the associated disk resource.
the SAN (MSA P2000) has no problem, and also there are another LUNS for another Servers working fine.
also sometimes when i restart both nodes, two LUNs from the four LUNs appeared in my computer but after awhile they are disappeared from both nodes.
also on the disk management of both nodes the four LUNs are shown as reserved!!
please help me in this issue
