36 Planning: MD3200 Series Storage Array Terms and Concepts
Physical Disks
Only Dell™ supported 6.0-Gbps SAS physical disks are supported in the
storage array. If the storage array detects unsupported physical disks, it marks
the disk as unsupported and the physical disk becomes unavailable for all
operations.
NOTE: The MD3200 Series array must contain at least two physical disks for proper
operation. This is necessary because the physical disks are used to store
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.
