摘要： A storage apparatus 10 includes channel devices (each being CHA_PK 11) and microprocessors (each being MP_PK 12). CHA_PK 11 and MP_PK 12 respectively store therein control information being information designating logical volumes (LDEVs) 171 accessible by respective MP_PKs 12. Upon receipt of an I/O request from a management apparatus 20, CHA_PK 11 transmits, based on the control information stored therein, an I/O command to MP_PK 12 having an access right to a logical volume to which the I/O request is directed. In the storage apparatus 10, MP_PK 12 having received the I/O command from CHA_PK 11 judges based on the control information stored therein whether MP_PK 12 itself has an access right to the logical volume, and transmits the control information therein to CHA_PK 11 when judging that it does not have the access right, whereby the control information in CHA_PK 11 is updated.

摘要： The present invention provides a storage control subsystem that facilitates logical volume access management by a host. Before copying, the host instructs a disk array device to identify the states of target logical volumes and collect information in control memory, whereupon the disk array device reads information in the control memory and reports information relating to the target logical volumes to the host.

摘要： A control technique for resident information or release of resident information in a cache memory is provided, by which residence is set into a cache memory without regard of a logical volume where a dataset is present, and an unused resident area in the cache memory is automatically deleted. In an information processing system, a host system has a resident management program for automatically acquiring a logical volume name from a dataset name specified by the user with reference to catalog information for managing dataset stored in the logical volume and instructing the dataset on the logical volume having the corresponding logical volume name to be resident. Further, a disk array system has microprogram for making the dataset on the logical volume having the corresponding logical volume name resident in the cache memory in response to the instruction to set residence from the resident management program.
