Hello,<o:p></o:p>
I am trying to setup a 3 nodes Windows Cluster to take advantage of SQL Always On failover feature.
I have 3 VM's running on VMWare, inside my company’s datacenter (not Azure), with Windows Server 2016 DataCenter installed on each. I can create the cluster with those 3 nodes, they are not joining any Active Directory (DNS only). I want to use Storage Spaces Direct as shared storage, and this is where I am stuck.
On each 3 nodes, I have 4 disks. From the “Get-PhysicalDisk” PS command result, for all disks, MediaType is SSD and BusType is SAS. I have
one disk as the boot volume, one disk to store various files, and 2 disks with an unused partition. These 2 last disks are the ones I want to use with S2D, and they are marked as CanPool=True.
When I run the “Get-PhysicalDisk” PS command from the first node, the disks showing up in the list are : the boot disk and the file disk from node 1, and 6 poolable disks (2 disks from each 3 nodes).<o:p></o:p>
From the S2D validation report (launched from the Failover cluster manager), the 6 poolable disks are marked as "eligible for validation=True"
with these characteristics :
Disk partition style is MBR. Disk has an Unused Partition. Disk type is BASIC.
while the others disks (boot volume and file disk) are reporting a warning (I am not sure if it is a problem preventing the enability of S2D...) :
Failed to get SCSI page 83h VPD descriptors for physical disk 0.
and have those characteristics :
Disk 1 : Disk is a boot volume. Disk is a system volume. Disk is used for paging files. Disk partition style is MBR. Disk has an Unused Partition. Disk has an IFS Partition. Cannot cluster a disk with an IFS Partition. Disk type is BASIC. The required inquiry
data (SCSI page 83h VPD descriptor) was reported as not being supported.
Disk 2 : Disk partition style is MBR. Disk has an Unused Partition. Disk has an IFS Partition. Cannot cluster a disk with an IFS Partition. Disk type is BASIC. The required inquiry data (SCSI page 83h VPD descriptor) was reported as not being
supported.

When I want to enable S2D from PowerShell command prompt, I receive an error saying : "No disks with supported bus types found to be used for S2D", even if the bus type is SAS.<o:p></o:p>

I am not an expert on managing servers, and I may have overlooked something during the setup. If more information on my setup is needed, I can provide them to the best of knowledge. I wanted to put some screenshots but since my account is not verified yet it was impossible, I have put as many details as I could.<o:p></o:p>
Thank you for any advice provided.<o:p></o:p>
