Using the LUN Logical Drive ID
To display the Linux name assigned to each of the logical volumes, use the lsvdev utility, as
shown in Example 7-11.
Example 7-11 Displaying Linux disk names with lsvdev
[root@TC-2008 mpp]# ./lsvdev
Array Name Lun sd device
-------------------------------------
ITSO_5020 0 -> /dev/sda
ITSO_5020 1 -> /dev/sdb
ITSO_5020 2 -> /dev/sde
ITSO5300 0 -> /dev/sdc
ITSO5300 1 -> /dev/sdd
Use the mppUtil command, as shown in Example 7-12, to list the DS devices found together
with their characteristics. Use the parameter -g#, where # specifies the DS Subsystem ID
previously obtained by using the mppUtil -a command, as shown in Example 7-9 on
page 460.
Example 7-12 mppUtil -g0 - good condition
[root@TC-2008 ~]# mppUtil -g0
