Dell MD3620I, MD3600I owner manual Physical Disks, Physical Disk States

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 MD3600i storage enclosure 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.
