Restarting Multipathing

If your multipath configuration changes, you may need to restart multipathing, as in this example:

# multipathd -k

multipathd> reconfigure

multipathd> show config

multipathd> exit

When using the show config command, you will need to search through the output and make sure it

matches what was entered in

/etc/multipath.conf.

If the restart is not successful, you can try the following commands:

# multipath -F

# service multipathd stop

# service multipathd start

// confirm the new settings are used for existing multipath devices

# multipath –ll
