Thanks -- this was originally how Lenovo told us to check this, and I
came across `mmfsadm test verbs status` on my own.

I'm thinking, though, isn't there some risk that if RDMA went down
somehow, that wouldn't be caught by your script? I can't say that I
normally see that as the failure mode (it's most often booting up
without), nor do I know what happens to `mmfsadm test verbs status` if
you pull a cable or something.
