39 Dell EMC SC Series Storage with SAS Front-end Support for Microsoft Hyper-V | 3026-CD-WS | V3
5.2 Windows Server 2012 R2 and newer
For MPIO-enabled guest VMs running on Windows Server 2012 R2 and newer, complete the following steps
for each guest VM, substituting the name of the VM for Vm_Name. For guest VMs running on Windows Server
2008 R2 or 2012, see section 5.1.
1. From the server that owns the VM, launch PowerShell with elevated (administrator) privileges, and
run the following commands:
$HyperVGuestName = "Vm_Name";
$VMManagementService = gwmi –Class "Msvm_VirtualSystemManagementService" -
Namespace "root\virtualization\v2"
$Vm = gwmi -Namespace "root\virtualization\v2" -Query "Select * from
Msvm_ComputerSystem Where ElementName = '$HyperVGuestName'"
$SettingData = gwmi -Namespace "root\virtualization\V2" -Query
"Associators of {$Vm} Where ResultClass=MSVM_VirtualSystemSettingData"
$SettingData.AllowFullSCSICommandSet = $true
$VMManagementService.ModifySystemSettings($SettingData.GetText(1))
2. Reboot the VM.
3. Present one or more SAS pass-through disks to the guest VM.
4. Repeat steps 2–3 for additional VMs.
