Re: Check the multipath - RHL 5X
do you mean testing if multipathing is working or if the software is installed?

Re: Check the multipath - RHL 5X
multipathd -k
You would get a multipath shell as shown below, press enter to get the various options to manage and list the various multipath controlled devices.

Re: Check the multipath - RHL 5X
If you have results after you run this command "multipath -ll", it means that it's installed.
It should show that all 4 paths are "active"
Now if you have 4 paths on your LUN's, I suppose you have 2 FC cards with 2 paths each to your LUN's.
Next pull the fiber from one the card and re-run "multipath -ll". You should see 2 paths "failed".
Also, after pulling the plug, verify that you still have access to your data ;-)
Plug in the cable again and re-run "multipath -ll" to check if all 4 paths are "active".
Rinse and repeat for all FC cards.
That should do the trick to validate that your multipathing setup is fault tolerant.
