Dell POWERVAULT MD3600F - Manual (Page 42)

42 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 storage 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
Table 4-1 describes the various states of the physical disk, which are
recognized by the storage array and reported in the MDSM application.
