3. The Start script is run on the server where the virtual host is becoming
active.
PARALLEL. The strict ordering sequence for Stop and Start scripts is not
enforced. The scripts run in parallel across the cluster as a virtual host is
in transition.
The
PARALLEL configuration can speed up failover time for services 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 ClusterPulse does not have to wait for the failing server
to finish running its Stop script.
To configure script ordering from the command line, use this option:
--ordering serial|parallel
Other Configuration Procedures
These procedures can be performed from the Servers, Virtual Hosts, or
Applications tabs on the HP CFS Management Console or from the
command line.
Delete a Service Monitor
From the Management Console, select the service monitor to be deleted,
right-click, and select Remove From Server.
To delete a service monitor from the command line, use this command:
mx service delete <vhost:port>
Disable a Service Monitor on a Specific Server
When a monitor is disabled, the health of the server is affected in the
same manner as a failure of the monitor’s probe operation. If the Policy
configuration of the monitor is either
AUTORECOVER or
NOAUTORECOVER, the ClusterPulse process will attempt to fail over the
virtual host associated with the monitor to a backup node. If a backup
node is not available or if the Policy configuration of the monitor is
NOFAILOVER, the virtual host will remain on the original node. The
monitor will continue probing and will report the status of the service as
