System and method for adding a storage device to a cluster as a shared resource

摘要

A system and method are described for adding a disk to a cluster as a shared resource. In one embodiment, a request is received to add a disk to a cluster as a shared disk resource. The disk may share a disk identifier with a second disk currently connected to the cluster as a shared resource. A determination is made as to which partition format is used by the disk. A unique disk identifier is retrieved and written to the disk in accordance with the determined partition format. The disk is then connected to the node as a shared disk resource. The disk may be a snapshot, mirror, or backup of the second disk currently connected to the cluster.
