Fail Over cluster problem
I am trying to add disk under storage . This is suppose to be quorum disk for fail over windows cluster. It has been presented via Power Path. But whenever I run cluster validation it throws error :
Cluster Disk 0 does not support Persistent Reservations. 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.
When I spoke to SAN guy he told "SCSI Persistent Reservation" is set to enable on all the lun.
Anyone have seen this?

Hello. If you run this command from one of the nodes: 'emcphostid check -host clusternode1 clusternode2 clusternode ' what does it return? Also, what's the storage array?

This is what I get
C:\Users\xenadmin>emcphostid check -host xxx001
Host: XXX001 - HostId: 0x5AA86EF1
C:\Users\xenadmin>emcphostid check -host xxx002
Host: xxx002 - HostId: 0x1EE23279
C:\Users\xenadmin>emcphostid check -host xxx003
Host: xx003 - HostId: 0x7B898449
C:\Users\xenadmin>emcphostid check -host xxx004
Host: xxx004 - HostId: 0x30E749D2
C:\Users\xenadmin>emcphostid check -host xxx005
Host: xxx005 - HostId: 0x9AFC3706
C:\Users\xenadmin>emcphostid check -host xxx006

Those look good. The command returned and the values are unique. If you add the LUN that is failing validation to the "available storage" cluster group, or to an empty group, does it come online and can it be moved between the nodes? If not I'd double check and make sure the PER flag is set on the LUN. If the disk works in the cluster but validation still fails, you may need to open a support case.

Looks like we both are online. Now here is the thing, MS says "
When added more nodes, again got Disk errors in Cluster Validation.
“Failed to access sector 11 on disk with identifier fee80203 from node XXX ”
Recommended involving Storage vendor to correct the Storage configurations. PR Reservations are not cleared.
"
Storage team says "SCSI Persistence Reservation " Enabled
So do you think EMC still can look at this?
