Validate SCSI-3 Persistent Reservation error

I'm creating a Windows 2016 cluster with 2 nodes and a couple of shared disks from a 3PAR 8440 and the cluster validation is failing with the following warning from both nodes:

"The test has detected that the Presistent Reservation command took longer than 3 seconds to complete. This may impact cluster stability."

If I ignore the warning and proceed to create the cluster it takes a long time and then it fails with these errors:

Creating the physical disk resource for 'Cluster Disk 1'.

Bringing the resource for 'Cluster Disk 1' online.

There was an error creating, configuring, or bringing online the Physical Disk resource (disk) 'Cluster Disk 1'.

Creating the physical disk resource for 'Cluster Disk 2'.

Bringing the resource for 'Cluster Disk 2' online.

There was an error creating, configuring, or bringing online the Physical Disk resource (disk) 'Cluster Disk 2'.

In the past I was able to create similar configurations in Windows 2012 R2 with no issues. Any suggestion?

Thank you.

    Hi,

    Please check if the following information could be of help:

    Generally, the issue can be caused by one of these situations:

    If you are attempting to set up a Cluster in a Single Host, and the shared disk (or disks) for the cluster is RDM (Raw Device Mapping, or Raw Disk Mapping), in Physical Compatibility Mode. If this is the case, you can either change the disks to Virtual Compatibility mode, or if you wish to use Physical Compatibility Mode, the cluster nodes must be on different hosts.

    If the storage array is not configured correctly to support SCSI-3 compliant commands.

    A third-party plug-in is interfering with the SCSI reservation process (such as the PowerPath/VE PSA).

    If virtual machines are running under the MSCS configuration on two separate ESX/ESXi hosts, and the .vmdk files are on a VMFS datastore which is configured as physical bus sharing mode. (This configuration of CAB is unsupported). For more information, see the Cluster Virtual Machines on One Physical Host section of the Setup for Failover Clustering and Microsoft Cluster Service Guide.

    I'm setting the windows cluster with two nodes. I'm no sure how to change the disk mode in windows (this might apply to VMware), I don't have VMware, I just want to configure a basic Windows 2016 cluster with a couple of clustered disks from a SAN. Disk are RAID 6, SAN is a 3PAR 8440.

    Hey,

    Did you initialize the connected drives as NTFS or ReFS on the hosts before running the validation? It is required for Failover Cluster.
    Another thing, did you configure MPIO properties with 3par? You can find more information here:
    https://h20195.www2.hpe.com/V2/GetPDF.aspx/a00030078enw

    I haven't found full Failover Cluster configuration guide with 3par, but the following guide might help:

    Hi Alex,
    I did initialize the drives as NTFS in the first node and verified they were visible in the second node from Disk Management. I did configure MPIO by adding the 3PARdataVV id to the device list. The option Patch Verify Enable is not checked since I understand that this is for multisite deployments. I checked the guide in the second link but could find anything there. Any other suggestion?
    Thank you,
