Validate SCSI-3 Persistent Reservation: Test is not applicable - windows 2019 cluster - on vvols

Hello,

I have a 2 node cluster with windows 2019 core OS VM running on VMWare ESXi hosts.
The disks are created from VVol datastore and test-cluster on storage shows "Test is not applicable" for few of the tests mentioned below.
Could anyone please share an information on why these tests are not applicable in my environment.

PS C:\Users\Administrator> Test-Cluster -Include Storage -Verbose
VERBOSE: Connecting to cluster on local computer PSP-TEST1.
VERBOSE: Performing verification
VERBOSE: Storage - List Disks: The test passed..
VERBOSE: Storage - List Disks To Be Validated: Test is not applicable.
VERBOSE: Storage - Validate CSV Network Bindings: The test passed..
VERBOSE: Storage - Validate CSV Settings: The test passed..
VERBOSE: Storage - Validate Disk Access Latency: Test is not applicable.
VERBOSE: Storage - Validate Microsoft MPIO-based disks: Test is not applicable.
VERBOSE: Storage - Validate SCSI device Vital Product Data (VPD): Test is not applicable.
VERBOSE: Storage - Validate SCSI-3 Persistent Reservation: Test is not applicable.
VERBOSE: Storage - Validate Storage Spaces Persistent Reservation: Test is not applicable.

what storage vendor are you using?
were you able to pass the test?

I am using Nimble Storage. The above tests are skipped as "Not applicable" after the cluster creation.

One observation is if i bring the cluster disk offline, these tests passed. Does it mean, the storage tests need to be run after bringing the disks offline.

Hi,

Thanks for your posting!

Based on your descriptions, almost each test related to your clustered disk appears to be unapplicable in your environment and I have noticed that you used disks created from VVol datastore which belongs to VMware. On the other hand, tests related to our in-built services like CSV can be passed in your environment. So, I suppose you can seek for assistance from technical supporter for VMware products. Actually I have found an article about failure in Microsoft Windows cluster validation test. I know you just encountered warnings in your situation but my point is, something unapplicable does happen when you use VMware VVol datastore and Microsoft Cluster service. Here is the article:

In addition, I have found articles for you to better understand your issue:

Hey,

You would need shared storage to create Failover Cluster. In case you are using vSphere 7 you should be able to use Clustered VMDKs. The following link should help:
https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/solutions/vmw-vmdk-whitepaper-mmt.pdf

As an alternative, you can use StarWind VSAN as a shared storage option for the Failover Cluster. The following guide will walk you through the configuration process:

Hi Alex,

I am using shared storage only and also the disks are created from VVOL datastore.

Thanks for your time.
