STORAGE SYSTEM, STORAGE CONTROL APPARATUS AND METHOD

摘要

A storage system comprises a storage device for storing data, a control apparatus which controls the storage device and comprises multiple communication ports, and a switch apparatus which expands the number of storage device couplings and comprises multiple communication ports. Respective multiple communication ports of the control apparatus are coupled to respective multiple communication ports of the switch apparatus, and the switch apparatus is coupled to the storage device. The control apparatus configures at least one communication port of the multiple communication ports of the control apparatus, to a dedicated communication port for outputting only a prescribed command issued when a failure is detected.
