The SERIAL setting considers events and takes precedence over the setting for Event
Severity.
PARALLEL. HP Scalable NAS does not enforce the strict ordering sequence for Stop
and Start scripts. 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 HP Scalable NAS 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 lets you specify any virtual hosts that you want to fail over if
the device fails. (By default, no virtual hosts will fail over.) 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, HP Scalable NAS attempts to fail over the
active virtual hosts associated with that device monitor. By default, all virtual hosts
