Determining the Hardware ID to Be Managed by MPIO
Updated: September 30, 2009
Applies To: Windows Server 2008 R2
To determine the hardware IDs that are already managed by MPIO, open a command prompt, and then type MPCLAIM.EXE –H.
The hardware ID Vendor 8Product 16 is a placeholder value only to show the correct Vendor ID/Product ID format. This ID is not used to control the management of any disk devices.
To list the currently attached Vendor ID/Product ID for all disks on the system that can be claimed, open a command prompt, and then type MPCLAIM –E.
If the value in the MPIO-ed field is YES, the device is already claimed.
