PowerShell: some commands for working with disks, volumes, VGs
One-liner to format a new disk as a single NTFS partition:
Get-Disk $DiskId | Initialize-Disk | New-Partition -UseMaximumSize | Format-Volume -Filesystem "NTFS" -AsJob -DriveLetter "Z"
Get-Partition will get you volumes (code block is missing MSR & EFI for brevity):

Get-PhysicalDisk will give you serial numbers (the actual disks, if you can believe that)
Can also be used to remove all the partitions on a disk pretty easily:
Get-Disk series of cmdlets work with logical disks (kinda sorta a volume command?)

TODO: I have some BitLocker stuff to add here. Eventually. Maybe?
get-physicaldisk -SerialNumber 21294T805133 | get-disk | get-partition | remove-partition
Or reset disks:
Get-PhysicalDisk -SerialNumber 21294T805133 | Reset-PhysicalDisk
Disks may (always?) require a reset to toggle their CanPool state, even if there’s nothing on them.
PS C:\Users\Administrator> get-physicaldisk -SerialNumber 21294T805133 | select CanPool

-------
False
PS C:\Users\Administrator> get-physicaldisk -SerialNumber 21294T805133 | reset-physicaldisk
PS C:\Users\Administrator> get-physicaldisk -SerialNumber 21294T805133 | select CanPool
CanPool
-------
True
Create a pool by resetting a PhysicalDisk for use as a PV then creating a VG
New-StoragePool -FriendlyName SsdDataPool0 -StorageSubsystemFriendlyName (Get-StorageSubsystem).FriendlyName -PhysicalDisks (Get-PhysicalDisk -CanPool $true)
$PoolMembers = Get-PhysicalDisk -SerialNumber 21294T804630
$PoolMembers | Reset-PhysicalDisk
