1. A storage management method partitioning a physical resource and a logical resource in a storage subsystem, allocating a management user per partition unit, and performing partition management of each of said resources, the storage subsystem having a plurality of channel adapters coupled to a host computer and receiving data from the host computer, a cache memory temporarily storing data sent from the channel adapters, a plurality of disk adapters receiving data stored in the cache memory, a plurality of physical disks connected to said disk adapters and storing data sent from the disk adapters, a shared memory, and a switch for connecting said plurality of channel adapters, said plurality of disk adapters, said shared memory, and said cache memory, the storage management method comprising the steps of:

  • storing, in said shared memory in said storage subsystem, a program-product management table showing presence or absence of a program product that provides a configuration-changing function for each of said resources, said resources including partitioned channel adapters, a partitioned cache memory, and a logical disk drive group relating to a storage area of the physical disks, in a partition unit;

    referring to said program-product management table at the time of executing the configuration-changing function by said program product of each of said resources in the partition unit of said management user in accordance with an instruction from said management user; and

    restricting execution of the configuration-changing function of a resource without said program product.
