Planning: MD3200i Series Storage Array Terms and Concepts 39If a disk drive rebuild fails because of a source drive failure or because thedrive is too small, the MDSM reports a failure of the physical disk eventhough the LED state on the drive indicates the rebuild was aborted (greenfor 3 seconds, amber for 3 seconds, then off for 3 seconds).Self-Monitoring Analysis and Reporting TechnologySMART monitors the internal performance of all physical disk components todetect faults indicating the potential for physical disk failure. SMART usesthis information to report whether failure is imminent so that a physical diskcan be replaced before failure occurs. The storage array monitors all attacheddrives and notifies you when a predicted failure is reported by a physical disk.Virtual Disks and Disk GroupsWhen configuring a storage array, you must:1 Organize the physical disks into disk groups.2 Create virtual disks within these disk groups.3 Provide host server access.4 Create mappings to associate the virtual disks with the host servers.NOTE: Host server access must be created before mapping virtual disks.Offline Not applicable The physical disk has either been spundown or had a rebuild aborted by userrequest.Green flashing(3000 ms), Amber(3000 ms), andOff (3000 ms)Identify Assigned,Unassigned,Hot Spare inuse, or HotSpare standbyThe physical disk is being identified. Green flashing(250 ms)N/A N/A The indicated slot is empty, or thearray cannot detect the physical disk.Table 4-1.
