4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

The following example shows the state transitions for a custom device monitor and
its associated virtual host. The device monitor uses the default values for autorecover,
priority, and serial script ordering, and has a Start and Stop script defined. The virtual
host is configured with a Primary network interface and two backup interfaces. There
is also a service monitor defined on the virtual host. It uses the default values for
autorecovery, priority, and serial script ordering and has Start and Stop scripts
defined.
The example begins at initial startup from an unknown state and the virtual host is
then located on the primary interface.
At time t1, the service monitor probe on the Primary reports a Down status. The virtual
host then becomes inactive all servers.
The virtual host cannot be active on the Primary server because the custom service
monitor is Down. It cannot become active on either of the backup servers because
the custom device monitor associated with the virtual host is Inactive on these servers.
