DISK LIST displays a list of the disks installed in the system and indicates how many were found.
DISK SCAN checks each disk channel in the system for any new disks and verifies that the existing disks
are in the correct location. DISK SCAN also starts a rebuild operation on any failed disks which pass the
disk diagnostics.
DISK STATUS displays the loop status of each disk channel and a count of the SAS errors encountered
on each channel (Figure 3–10).

.
The tier
is in the range of <1..125>. The channel is one of the following: A, B, C, D, E, F, G, P, or S. The list is
classified into two types: G (Grown) and P (Permanent) (Figure 3–11).
The G list consists of the sectors that have become bad after the disk has left the factory and which can
be added to at any time. The P list consists of the bad sectors that are found by the disk manufacturer .
