PARALLEL. The strict ordering sequence for Stop and Start scripts is not enforced. The
scripts run in parallel across the cluster as a shared device or virtual host is in
transition.
The PARALLEL configuration can speed up failover time for services and devices that
do not depend on strict ordering of Start and Stop scripts. Assuming that it is safe to
run the scripts in parallel (which depends on your application), this setting can also
increase the chances of a successful failover because Matrix Server does not have
to wait for the failing node to finish running its Stop script.
To configure script ordering from the command line, use this option:
--ordering serial|parallel
Virtual hosts
The Virtual Hosts tab you specify the virtual hosts that will fail over if the monitor
detects a failure. If you want all virtual hosts to be dependent on the device monitor
and to fail over if the device fails, check Select All Virtual Hosts.
When a device monitor detects a failure, Matrix Server attempts to fail over the active
virtual hosts associated with that device monitor. By default, all virtual hosts on the
servers used with the device monitor are dependent on the device monitor. However,
you can specify that only certain virtual hosts be dependent on the device monitor.
