Use the multipathd -k interactive console to troubleshoot multipath issues in real time. This console provides access to status info, config details, and control commands. Type help for commands and press Ctrl+D to exit without disrupting services.
Procedure
Display the multipath configuration, including the default values, before exiting the console:
# multipathd -k multipathd> show config multipathd> Ctrl+DEnsure that multipath picked up all changes to the
multipath.conffile:# multipathd -k multipathd> reconfigure multipathd> Ctrl+DEnsure that the path checker is working properly:
# multipathd -k multipathd> show paths multipathd> Ctrl+DYou can also run a single
multipathdinteractive command directly from the command line, without starting the interactive console. For example, to check that multipath picks up all changes to themultipath.conffile, run the following command:# multipathd reconfigure
