PLURALITY OF COUPLED STORAGE SUBSYSTEMS AND METHOD FOR SETTING PORT ACCESS LIMITATION IN A STORAGE SUBSYSTEM WHEN MIGRATING A LOGICAL VOLUME

摘要

It is provided a storage subsystem, comprising: a storage device which provides a volume for storing data; a processor which executes a program for controlling the storage subsystem; a memory which stores data used by the processor; and a port which is coupled to another storage subsystem. The memory stores interface management information, which holds a use of the port in migration, and port management information, which holds a use of a port of the another storage subsystem in migration. The processor refers to the interface management information and the port management information to identify a port of the another storage subsystem which is permitted to communicate with the port of the storage subsystem, in order to determine a communication zone of the port coupled to the another storage subsystem for migration.
