PowerShell offers a direct and efficient method to manage MPO settings.

  1. Open PowerShell as Administrator
  • Press Windows + X and select Windows Terminal (Admin) or PowerShell (Admin).
  • Confirm the User Account Control prompt.
  1. Check Current MPO Status

Execute the following command to verify if MPO is enabled on your system:
“`powershell
Get-MSDSMGlobalDefaultLoadBalancePolicy
“`
This command outputs the current load balancing policy and indicates if MPO is active.

  1. Disable MPO Globally

To disable MPO system-wide, run:
“`powershell
Set-MSDSMGlobalDefaultLoadBalancePolicy -Policy “None”
“`
This command sets the load balancing policy to “None,” effectively disabling MPO.

  1. Verify the Change

Re-run the status command to ensure the policy has been updated:
“`powershell
Get-MSDSMGlobalDefaultLoadBalancePolicy
“`
Confirm that the policy now reads “None.”

Disabling MPO for Specific Devices

If you prefer to disable MPO on individual storage devices rather than globally, use the following approach:

  • List multi-path devices:

“`powershell
Get-MSDSMDevice
“`
This command displays all MPO-enabled devices.

  • Disable MPO on a target device by specifying the device’s unique identifier:

“`powershell
Set-MSDSMDeviceLoadBalancePolicy -DeviceId “” -Policy “None”
“`
Replace `` with the actual device identifier from the previous output.

Disabling MPO via Device Manager

While the primary control of MPO is through PowerShell, you can also attempt to disable it via Device Manager:

  • Open **Device Manager** by pressing **Windows + X** and selecting **Device Manager**.
