Simple...ping by IP address. Let the cluster worry about the actual node you attach to in the case of B. Unless you can ping the unique IP addresses of the nodes that comprise the cluster (this of course depends on how the ip address is "shared" on the cluster nodes; i.e. round-robin) .
You can test the success/failure of the ping or the sftp (the ping is probably faster to give results since you can control it with a -c Count and -w timeout options). I would also trust ping more so than sftp for returning status of failure or success.
So you can do something like...
or suppose you can ping the unique addresses of cluster B, say B1 and B2 (make sure you can, because cluster nodes unique ip addresses could be on a different segment depending on the cluster)...not really different...
I did not test this but you should be able to get the idea.
