3. Run the Get-PmemUnusedRegion | New-PmemDisk script to create two Pmem disks, one for each Pmem region.

PS C:\> Get-PmemUnusedRegion | New-PmemDisk

Creating new persistent memory disk. This may take a few moments.

4. Run the Get-PhysicalDisk | ?{$_.MediaType -eq "SCM"} script to verify that both Pmem disks are available as physical

disk devices.
