Add or Remove MPIO Support

Applies To: Windows Server 2008 R2

For Multipath I/O (MPIO) to manage a device, you must first add the hardware ID that corresponds to the device that you want to add to MPIO.

You can view the hardware IDs of devices that are currently managed by MPIO on the Discover Multi-Paths tab. The ability to view a device is based on its hardware ID, which combines a vendor’s name and a product string that matches a device ID that is maintained by MPIO in its supported device list. Every Device Specific Module (DSM) specifies a product string in its .inf file at the time of installation.

To specify another MPIO device, click Add, and then in the Add MPIO Support dialog box, enter the device information.

noteNote
The vendor and product IDs are provided by the storage provider, and are specific to each type of hardware.

To remove a device, select it from the list, and then click Remove.
