Method and system for managing storage system using first and second communication areas

A system for managing a storage system, comprising:

• one or more processors;
• a memory coupled to at least one processor of the one or more processors:
• computer program instructions stored in the memory which, when executed by the at least one processor, cause the system to execute a method for managing a storage system, the method comprising;
• in a storage system comprising a first controller, a second controller, and a plurality of storage devices configured as a redundant array of independent disks (RAID), with respect to a storage device in the storage system,
• in response to the first controller successfully accessing the storage device, writing to a first communication area a first state that indicates a state relationship between the first controller and the storage device, the first communication area being deployed across the RAID such that state data including the first state is recoverable in the event of failure of one of the storage devices, the first communication area being readable and writable to the first controller and readable to the second controller;
• reading from a second communication area a second state that indicates a state relationship between the second controller and the storage device, the second communication area being deployed across the RAID such that the state data including the second state is recoverable in the event of failure of one of the storage devices, the second communication area being readable to the first controller and readable and writable to the second controller;
• and
• initializing the storage system in response to the second state indicating that the second controller successfully accesses the storage device.
