A.2.2. The dmsetup ls Command

You can list the device names of mapped devices with the dmsetup ls command. You can list devices that have at least one target of a specified type with the dmsetup ls --target target_type command. For other options of the dmsetup ls, see the dmsetup man page.

The following example shows the command to list the device names of currently configured mapped devices.

[root@ask-07 ~]# dmsetup ls
testgfsvg-testgfslv3    (253, 4)
testgfsvg-testgfslv2    (253, 3)
testgfsvg-testgfslv1    (253, 2)
VolGroup00-LogVol01     (253, 1)
VolGroup00-LogVol00     (253, 0)

The following example shows the command to list the devices names of currently configured mirror mappings.

Note to reviewers: We'll come up with better names for the devices here.

[root@grant-01 ~]# dmsetup ls --target mirror
lock_stress-grant--02.1722      (253, 34)
lock_stress-grant--01.1720      (253, 18)
