Adding a Hardware ID for Use with MPIO and Viewing Hidden Devices
Updated: September 30, 2009
Applies To: Windows Server 2008 R2
-
Open the MPIO control panel.
-
On the MPIO Devices tab, click Add.
-
In the Add MPIO Support dialog box, type the hardware ID for the device that you want to be managed by MPIO, and then click OK.
Note For a list of all hardware IDs for all currently attached devices, open a command prompt, and then type mpclaim –E. You can copy and paste the ID that you want to be used with MPIO in Step 3 of this procedure, but do not include the beginning or ending quotes around the hardware ID.
After the device is claimed by MPIO, it is hidden in Device Manager and a pseudo-LUN device is shown in Device Manager.
For example, the single path disk device listed in Device Manager that is named “emBoot sanFly SCSI Disk device” becomes a hidden device, and is replaced with a new device named “emBoot sanFly Multi-Path Disk Device.” The exact name depends on several factors, including the type of device and the DSM being used.
-
To view the original disk device, in Device Manager, on the Action menu, click Show Hidden Devices.
