Can a coffer disk be replaced by the coffer disk in another controller enclosure?
No. Coffer disks are used to store important data for the storage system, including configuration data, event information, and log information. When the storage system encounters an unexpected power failure, data in cache is written onto coffer disks. Even the two controller enclosures are of the same manufacturer and type, data stored on their coffer disks is different; therefore, coffer disks in different controller enclosures cannot be interchanged.
