Do not use that...
How does that actually fence the offending node when it needs to?

The concept of fencing is for the preservation of data integrity, circumventing
it with a manual fence is useful only for testing, if you need to fence
an errant node in production and don't, it might just corrupt your shared
storage. Sigh...

Make a firewall provision, it's imperative you get fencing right.
