Abstract
When the main power source is turned on, a storage system creates a revision table for storing the revision of main firmware installed in a resource management processor of the storage system. Next, the main firmware is loaded from a system drive into a cache memory. When the revision of the main firmware installed in the resource management processor is old, this main firmware is renewed to the main firmware loaded into the cache.
