Displaying private device information using sp_helpdevice

sp_helpdevice reports whether or not a device is private. If the device is private, sp_helpdevice prints the name of the instance in the cluster that owns the private device.

In this example, 'regular_dev'is a regular shareable device, while 'private_dev1' is a private device owned by instance 'cluster1_1'.

If disk refit is pending on a device, sp_helpdevice reflects it in its output.

In this example,'regular_dev' is a regular shareable device, while 'private_dev1' and 'private_dev2' are private devices owned by instance 'cluster1_l'. Further disk refit is pending on 'private_dev1'.
