Maintaining Cluster Communication
2–12 iSTAR eX Installation and Configuration Guide
Alternate Master Configuration
If the master loses its network connection with the host, or if the master
hardware fails, a secondary path can connect an alternate master and the host
(Figure 2.8).
The following describes the sequence of events:
The alternate master establishes a connection with the host via the
secondary path.
Cluster members establish connections with the alternate master via the
network.
The alternate master sends the cluster members’ messages to the host, and
also sends messages from member to member.
