HP StorageWorks XP Cluster Extension Software Administrator Guide (T1656-96035, April 2010)

Including the XP Cluster Extension resource type
See “Importing the XP Cluster Extension resource types configuration file” in the HP StorageWorks
XP Cluster Extension Software Installation Guide.
Configuring the XP Cluster Extension resource
For VCS, you can configure an XP Cluster Extension resource using either the VCS CLI or the VCS
Cluster Manager GUI. The XP Cluster Extension resource gathers all necessary information about the
service group and the XP disk arrays if the XP Cluster Extension resource is brought online. Consider
the following:
• If you use the default values for XP Cluster Extension COMMON objects, no user configuration
file is required.
• If configured, a pair/resync monitor is started to monitor the XP Cluster Extension resource. If the
resource is not configured to use the pair/resync monitor, a file is created in the directory specified
by the ApplicationDir attribute: resource_name.online.
If the resource is taken offline, the file is removed or the device group associated with the service
group is removed from the pair/resync monitor list. If the device group is the last monitored disk
pair, the monitor is stopped also.
• The resource type definition file, ClusterExtensionXPTypes.cf, must be included in the VCS
configuration file main.cf. The XP Cluster Extension resource type definition is preconfigured for
the most typical cluster configurations. It comes with a sample configuration that can be modified
to fit your VCS and disk array environment.
XP Cluster Extension resource types
Before configuring the objects in the user configuration file, review the XP Cluster Extension objects
described in Chapter 8 on page 123.
