Multipath commands

Multipath commands are helpful when working with multipath topologies and configurations.

Two other multipath commands are helpful when working with multipath topologies and configurations.
multipath –ll
Shows the current multipath topology from all available information, such as sysfs, the device mapper, or path checkers. When a new device is added to a system that is running multipathing, run the multipath -v2 command so that the device can be monitored by the multipathing software.
multipathd –k
Puts your session into interactive mode. Commands can be used to list the current configuration or to change the configuration. For example, <show config> lists the current configuration, and <reconfigure> gets the latest configuration from the configuration file (etc/multipath.conf).
