HA monitor linkage

This section describes the linkage between management modules and the HA
monitor.

HA monitor overview

The HA monitor enables a failover from one system (including the programs)
to another to improve the reliability and capacity utilization of the system.
The HA monitor ensures that, immediately after a failure occurs in the active
server blade (active system) that is executing the business processing, the
standby server blade (standby system) automatically takes over for the faulty
server blade. This improves the reliability and capacity utilization of the
system without the operators having to pay any particular attention to the
system.
