A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). The system permits the isolation of a suspected faulty HDD to allow diagnostics to be performed without impacting operation of the rest of the system. Upon detection of a possible fault in a target HDD, a private zone is established including the target HDD and one of the sub-processors, thereby isolating the target HDD. The sub-processor performs diagnostic operations, then transmits its results to the adapter. A faulty HDD can then be fully isolated and the private zone is disassembled, allowing the sub-processor to rejoin the network.
