Hi all,
I did a research and find many similar issue in this forum. However, the issue persist.
There is a Windows Server 2012 R2 Hyper-V Failover Cluster in my lab, with HP P2000 storage with Fiber Channel. Everything goes well after a problem with one node(let's call it Node01) in the cluster. So I perform a reinstallation with Node01. After the fresh installation , the LUN for VMs show "unknown" in Disk Management on Node01, you can see the following screenshot. However, the LUN(from the same storage) for quorum is OK.
I try to add Node01 to the existing cluster and the cluster validation give the following warning.
Failure. Persistent Reservation not present on Test Disk 0 from node <<MY_SERVER_FQDN>> after successful call to update reservation
holder’s registration key 0xb.
Test Disk 0 does not support SCSI-3 Persistent Reservations commands needed to support clustered Storage Pools. Some storage devices
require specific firmware versions or settings to function properly with failover clusters. Please contact your storage administrator or
storage vendor to check the configuration of the storage to allow it to function properly with failover clusters.
If I ignore the warning and keep Node01 in the cluster and run the command:get-ClusterSharedVolumeState. It will show:
Node : Node01
StateInfo : BlockRedirected
