Chapter 3. Communication Paths

This chapter discusses the communication paths in a cluster running FailSafe and in a cluster running both FailSafe and CXFS (known as a coexecution cluster).

Communication Paths in a FailSafe Cluster

The following figures show communication paths in FailSafe.

Note: The following figures do not represent the cmond cluster manager daemon. The purpose of this daemon is to keep the other daemons running.
