STORAGE APPARATUS, CONTROL APPARATUS AND COMPUTER-READABLE RECORDING MEDIUM HAVING STORED THEREIN CONTROL PROGRAM

摘要

A storage apparatus includes a plurality of control devices configured to control access a plurality of storage devices, and a relay apparatus including a plurality of coupling devices, each of which is configured to couple the control devices so as to be communicable with each other. The relay apparatus includes, for each coupling device, a monitoring controller configured to perform monitoring of the relay apparatus. A first monitoring controller provided in a first coupling device from among the coupling devices notifies, when the first monitoring controller detects an abnormal state in the relay apparatus, a first control device from among the control devices of information relating to the abnormal state detected by the first monitoring controller. The first control device performs a decoupling process that decouples an abnormal part from the relay apparatus based on the information relating to the abnormal state received from the first monitoring controller.
