Abstract
A storage processor is configured to identify a first disk drive and a second shadow drive associated with the first disk drive to an initiator. The storage processor receives storage commands from an initiator. When the storage commands access the first disk drive, the storage processor issues a first storage operation to the first disk drive. When the storage commands access the second shadow drive, the storage processor issues different storage operations to the first disk drive that are not supported by the initiator.
