Azure Stack HCI - How to create a shared disk?

Question

There is a request for a shared disk for two Hyper-V virtual machines.

I'm from VMware background and not familiar with Hyper-V and its PowerShell commands.

The GUI interface of the Windows Admin Center of the Azure Stack HCI does not have the option to create a shared disk as in the Hyper-V Manager.

Answer 1

From the article below, I was able to figure out the commands to create the shared disk and add it to the VMs.

PS C:\ClusterStorage\Volume03\SharedDisk-HCIWIN12-HCIWIN21> Add-VMHardDiskDrive -VMName 3753D-HCIWIN12 -Path C:\ClusterStorage\Volume03\SharedDisk-HCIWIN12-HCIWIN21\HCIWIN12-HCIWIN21-disk01.vhdx -ShareVirtualDisk

PS C:\ClusterStorage\Volume03\SharedDisk-HCIWIN12-HCIWIN21> Get-VMHardDiskDrive -VMName 3753d-hciwin12

VMName         ControllerType ControllerNumber ControllerLocation DiskNumber Path
------         -------------- ---------------- ------------------ ---------- ----
3753D-HCIWIN12 SCSI           0                0                             C:\ClusterStorage\Volume01\imageStore\d...
3753D-HCIWIN12 SCSI           0                5                             C:\ClusterStorage\Volume01\imageStore\d...
3753D-HCIWIN12 SCSI           0                6                             C:\ClusterStorage\Volume01\imageStore\d...
3753D-HCIWIN12 SCSI           0                7                             C:\ClusterStorage\Volume01\imageStore\d...

Before I move on to adding this disk to another VM, I was thinking, why not add this disk to a separate disk controller.

After powering off the VMs and removing the shared disk from the first VM, below are the codes and the final results.

PS C:\ClusterStorage\Volume03\SharedDisk-HCIWIN12-HCIWIN21> Add-VMHardDiskDrive -VMName 3753D-HCIWIN12 -Path C:\ClusterStorage\Volume03\SharedDisk-HCIWIN12-HCIWIN21\HCIWIN12-HCIWIN21-disk01.vhdx -ShareVirtualDisk -ControllerType SCSI -ControllerNumber 1 -ControllerLocation 0
