Abstract: A connection control apparatus includes a linkup detector that detects a linkup with the host apparatus, a port information generator that generates port group information containing port information to identify a port of the storage apparatus whose linkup is detected by the linkup detector, a host information generator that generates host group information containing host information to identify the host apparatus whose linkup is detected by the linkup detector, a logical volume information generator that generates logical volume group information containing logical volume information to identify the logical volumes of all unallocated logical volumes, and an access processing information generator that generates access processing information associating the port group information, the host group information, and the logical volume group information.

Abstract: A storage controller that controls a storage apparatus including a storage area and a plurality of access paths to the storage area is provided, the storage controller including: an obtaining unit that obtains load information indicating loads of the plurality of access paths; a determining unit that determines whether or not access paths to the storage area are to be switched, based on the load information; an identifying unit that identifies a switch candidate access path when it is determined by the determining unit that access paths are to be switched; and a switch instructing unit that instructs to switch to the switch candidate access path identified by the identifying unit.
