If the LUN being displayed is a mirrored LUN (that is, mirrored across two component LUNs), the
show lun
lun_number
command shows details of the component LUNs, as shown in the following example:
sfs> show lun 17
LUN (WWID): raid_17
LUN (Number): 17
Device: /dev/hpls/dev17a
Array (WWID): -

4.5 Viewing array information
The
show array
command shows information on all of the arrays in the system. To view array information,
enter the
show array
command as shown in the following example. This example is from a system where
SFS20 storage is used:
sfs> show array
Array Type Array (WWID) Disks Free Server
----- ------- ----------------- ----- ----- ---------------
1 MSA20 P6C8CX7MQPS7X6 12 0 south[1-2]
2 MSA20 P6C8CX7MQPS7TU 12 0 south[1-2]
3 MSA20 P6C8CX7MQPSU67 12 0 south[3-4]
4 MSA20 P6C8CX7MQPS7XG 12 0 south[3-4]
Note that within the SFS CLI, the
Type
field for SFS20 arrays displays the value
MSA20
.
Use the following information to help you to understand the output:
• The array numbers are assigned as the arrays are discovered by the system.
• If there are any connection problems between an array and the servers attached to the array, the
status of the servers attached to the array is shown (in systems where SFS20 storage is used).
• In the output from the
show array
command on a system where EVA4000 storage is used, the
Server
,
Disks
, and
Free
fields are blank for the EVA4000 arrays.
To see more information about an array, enter the
show array
command for the array, as shown in the
following example. This example is from a system where EVA4000 storage is used:
sfs> show array 2
