I need to get some examples documented here as reference for another post so this will be skinny but I will circle back and make it more complete later.
Getting Physical Disk Information
Get-PhysicalDisk Get-PhysicalDisk |fl *Friendly*,*Media*,*Size*,*Serial*
Changing Physical Disk Properties
Note that Physical Disk properties can only be changed for disks that are in a non-Primordial storage pool. Once the disks are removed from a storage pool, the manually assigned properties revert.
$disk = Get-PhysicalDisk -SerialNumber 600029212* Set-PhysicalDisk -InputObject $disk -NewFriendlyName HDD1 -MediaType HDD
