Figure 11.7. Web Admin Console view of HA setup from machine02's perspective
In this particular startup scenario, machine01 was started first, and, as there were no
other machines started in the cluster yet, machine01 assumed the role of the master, as you
can see in
figure 11.6
. If machine03 had started first, it would have assumed the role
of the master.
The Web Admin Console provides a rich set of details about the HA cluster, including
which other machines are involved in the cluster. This information can be found under the
InstancesInCluster section . The first machine shown here is actually machine01, but
