Abstract
When a failure occurs in a storage system controller, the controller reboots after completing prescribed failure processing for respective control parts. Upon detecting a failure, first, second, and third control parts of the controller perform respective failure processing. The first control part controls block access requests, the second control part controls file system access, and the third control part manages the second control part. The first control part and third control part write prescribed information to a storage area and reboot at least a portion of the controller upon detecting the failure.
