5.6. Multipath Queries with multipath Command
You can use the
-l and -ll options of the multipath command to display the current multipath configuration. The -l option displays multipath topology gathered from information in sysfs and the device mapper. The -ll option displays the information the -l displays in addition to all other available components of the system.
When displaying the multipath configuration, there are three verbosity levels you can specify with the
-v option of the multipath command. Specifying -v0 yields no output. Specifying -v1 outputs the created or updated multipath names only, which you can then feed to other tools such as kpartx. Specifying -v2 prints all detected paths, multipaths, and device maps.
The following example shows the output of a
multipath -l command.
# multipath -l
