[ClusterLabs] Stonith hostname vs port vs plug

host name (if they differ).
I understand the difference between plug and hostname. I don't clearly
understand which fence config is correct (I reffer to pcs stonith describe
fence_...):

the same entry on every node:
pmck_host_map="node1:Centos1;node2:Centos2"

or different entry at every node like this:

port=Centos1 (on node1)
port=Centos2 (on node2)
?
Thanks,
Regards
