HP 3PAR Cluster Extension Software Administrator Guide for Windows (5697-1821, April 2012)

HP 3PAR Cluster Extension requirements for service or application properties are described in
Table 2 (page 32). If no specific value is required, the default value is listed. Set these values in
the Failover tab of the service or application properties window (Windows Server 2008/2008
R2), the resource group properties window (Windows Server 2003), or in the CLI. For more
information about setting service or application properties, see your Microsoft documentation.
TIP: To change the properties in Table 2 (page 32) with the CLI, use the following command:
cluster group groupname /prop propertyname="propertyvalue".

after the failure has been
recovered. This allows
recovery of all possible
failure sources and pair
resynchronization (if
necessary) while the
application service is still
running.

systems are not members of
the cluster, the service or
application might restart
automatically.
If this value is set to a

the service or application
will continue to restart until
either the FailoverThreshold
value or the FailoverPeriod
timeout value is reached.
Setting HP 3PAR Cluster Extension-specific resource properties
Changes to resource properties take effect when the resource is brought online again. For instructions
on changing resource properties, see:
• “Setting HP 3PAR Cluster Extension resource properties using the GUI” (page 33)
• “Setting HP 3PAR Cluster Extension resource properties using the MMC ” (page 38)
