Abstract:
1. A disk drive diagnosis apparatus in a RAID system in which a RAID controller and a drive enclosure that encloses a disk drive are interconnected via a fabric switch, the apparatus comprising: a storage which stores a disk drive diagnosis result table that stores results of loop initialization diagnoses and login diagnoses relative to numbers of disk drives; a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute, virtually executing a login process in place of a fabric switch of a disk drive and accepting a login from the disk drive based on the disk drive diagnosis result table; and notifying the RAID controller of a result of the virtual login process and disconnecting from a connection line for the RAID controller the disk drive if the disk drive has not normally performed the virtual login process relative to the drive enclosure, determining the disk drive is normal, and a login process relative to the fabric switch is correctly performed after the virtual login process is executed, if a test result is normal based on the disk drive diagnosis result table.
