40 Planning: MD3600f 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 MD3600f 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 are described in Table 4-1.
