If the channel status is “acquiring loop synchronization”, this may indicate a channel problem. Refer
to Section 4.1.2.2 for recovery information.
To get information about a specific disk, use the command: DISK INFO=<tier><channel>
The DISK LIST command displays a list of the disks installed in the system and indicates how many
were found.
The DISK SCAN command checks each disk channel in the system for any new disks and verifies that
the existing disks are in the correct location. This also starts a rebuild operation on any failed disks
which pass the disk diagnostics.
The DISK STATUS command displays the loop status of each disk channel and a count of the Fibre
Channel errors encountered on each channel
(Figure 3-10)
. To reset the Fibre Channel error counts,
issue command: DISK STATUSCLEAR
The DISK LIPINFO command displays the last LILP payload for all disk channels.
The DISK DEFECTLIST=<tier><channel> command displays the defect list information for a specified
disk
.
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 and P. The G (Grown) list consists of the bad sectors that
are found after the disk has left the factory and which can be added to at any time. The P (Permanent)
list identifies the bad sectors that are identified by the disk manufacturer.
