The key is unique to each node, but there is only on stonith object. For
fence_mpath, they are putting scsi keys on a shared stonith device.

This is part of my multipath.conf that shows the key.
$ cat /etc/multipath.conf
I am trying to set up a new cluster using fence_mpath. I'm not sure

I used the fence_scsi program, directly, to figure out the key when I
initially set up my clusters. With what I know now. I could make up a key.
Its a 8 character hex key. When you see it with mpath_persist, it will look
like 0x33c50000 (in the example above. It usually looks like that in the
logs, but don't put it like that in the config.
