Monitoring MPIO on Windows Server Core and Minimal GUI Installations

Windows Server can have different levels of GUI installed on the server. Core and minimal levels of GUI have the same limitations.

You can use the Get-DcsMpioInfo.ps1 script to view information for all disks recognized by DataCoreMPIO, including the disk number, volume name, paths to the volume, path selection, active adapters and the active DataCore Server.

To monitor MPIO:

1. From a Windows PowerShell command window, navigate to: C:\Program Files\DataCore\Host Integration Kit.
2. Run the following script: Get-DcsMpioInfo.ps1
3. Enter a disk number to see adapter states, target IDs, and LUNS for the disk.
4. Enter 'Q' to quit the PowerShell command.

Virtual disk information is read when the script starts. If virtual disks are added or removed (or other mapping changes are made), then quit and rerun the script to refresh the information.
