1. A storage system comprising:
- a storage control unit for receiving a data write request from a plurality of host computers which configure a plurality of host groups;
at least one storage unit coupled to said storage control unit, said storage unit has a plurality of storage regions for storing data;
wherein said storage control unit has security information indicating relationships between each of said host groups and each of said storage regions accessible for each of said host groups;
wherein said security information is used by said storage control unit to reject accesses from other host groups other than each of said host groups are permitted to access to each of said storage regions; and
wherein said storage control unit receives a Port Login (PLOGI) frame from a newly host computer which is newly coupled to said storage control unit, and acquires a World Wide Name (WWN) and a source identifier (S_ID) contained in said PLOGI frame from said PLOGI frame so that an administrator can select a storage region of said plurality of storage regions to be accessed from a host group belonging to said newly host computer by using said acquired WWN, without inputting a WWN of said newly host computer by said administrator.

Abstract
The storage regions under command of a storage controller can be simply enabled and disabled to access to by automatically registering connected host computers. Such system can be achieved by taking a step of acquiring N_Port_Name information included in a login frame from the host computers, and a step of displaying a table of access right of host computers to a logical unit under command of storage controller. A security table for the storage controller can be generated by supervisor'"'"'s setting the access enable/disable flag information.
