Abstract
A method is provided for a destination storage system to handle SCSI-3 reservations. The method includes discovering a volume on a source storage system when the source storage system exports the volume to the destination storage system, exporting the volume to host computer systems, locally registering keys for first paths to the destination storage system, and registering with the source storage system the keys for second paths to the source storage system. When one of the host computer systems requests to reserve the volume, the method includes locally reserving the volume for paths to the destination storage system with registered keys and performing reservation forwarding to request the source storage system to reserve the volume for paths to the source storage system with registered keys.
