STORAGE APPARATUS AND METHOD OF UPDATING CONTROL INFORMATION IN STORAGE APPARATUS |
摘要 |
<p>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.</p> |
