Abstract
A method is provided for a destination storage system to join a storage area network with a source storage system. The method includes discovering a volume on the source storage system when the source storage system exports the volume to the destination storage system and exporting the volume to the host computer systems. When a command to reserve the volume for a host computer system is received, the method includes determining locally if the volume is already reserved. When the volume is not already reserved, the method includes reserving locally the volume for the host computer system and transmitting to the source storage system another command to reserve the volume for the destination storage system.
