Hello,
I have 3 node MSCS setup running on ESX 5.1 virtual machines. I have mapped Raw device shared lun between the host. Once i created the cluster, all the dosk were online including witness disk. When i convert the available disks to cluster shared volume , all the disks went to failed state. I tried to bring them online but moving between nodes, but it did not help me.
when i see the cluster log, following error were seen
"Ownership of cluster disk 'Cluster Disk 1' has been unexpectedly lost by this node. Run the Validate a Configuration wizard to check your storage configuration."
"Cluster physical disk resource 'Cluster Disk 1' failed. The Cluster Shared Volume was put in failed state with the following error: 'Failed to get the volume number for \\?\GLOBALROOT\Device\Harddisk4\ClusterPartition1\ (error 2)'"
These error are appeared only when i convert disk to cluster shared volumes.
Setup Details:
OS: Windows 2012R2
3 Node Cluster setup
Machines are from ESX5.1 host
Raw lun from SAN mapped between 3 nodes
Note:
I have another MSCS setup running on same ESX host, where I have mapped Luns from Microsoft ISCSI target , i dont find any issue with the configuration when i have CSV's. Only i can see issues with RDM Luns
Thanks,
