NOTE: The MD3200i storage enclosure must contain at least two physical disks for

configuration information.

Physical Disk States

The storage array recognizes the physical disk states. Mode and status of

physical disks are reported in the MDSM application. Possible values for

mode and status or described in Table 4-1.
