HP 3PAR StoreServ Cluster Extension Software Administrator Guide (5697-2442, July 2013)

The APPLICATION object requires the name of the application service as its value. The objects
specified after an APPLICATION tag must appear only once per application. As with COMMON
objects, APPLICATION objects have predefined default values.
HP 3PAR StoreServ Cluster Extension uses the following rules to define objects:
• If you use the default value, you do not need to specify the object.
• The pre-execution and post-execution functions in HP 3PAR StoreServ Cluster Extension will
not be processed if the associated object values are empty. This is the default setting.
To set APPLICATION object values for the CLI, modify the user configuration file.
To set APPLICATION object values for MSFC, use Failover Cluster Management GUI.
APPLICATION
Format Tag
Description Distinguishes between general and application-specific objects. Specify the name
of the application service. The format of its value is equivalent to a string value.
ApplicationDir
Format String
Description Specifies the directory where HP 3PAR StoreServ Cluster Extension searches for
application-specific files, such as the force flag or online file.
If ApplicationDir is set to a nonexistent drive, HP 3PAR StoreServ Cluster
Extension is unable to create the online file and cannot bring the resource online.
If ApplicationDir is not set, HP 3PAR StoreServ Cluster Extension uses the local
%HPCLX_3PAR_PATH% values as defined in the registry.
Default
values
%HPCLX_3PAR_PATH%
Files application_name.forceflag
CLX_application_name.online
If specified in a user configuration file, resource_name is the value of the
APPLICATION tag; otherwise, resource_name is the value of the HP 3PAR
StoreServ Cluster Extension resource name.
ApplicationStartup (Optional)
Format String
Description Specifies where a cluster group should be brought online.
The ApplicationStartup object can be customized to determine whether an
application service starts locally or is transferred back to the remote data center (if
possible) to start immediately without waiting for disk pair resynchronization. This
object is used only if an application service has already been transferred to the
secondary site and no recovery procedure has been applied to the Remote Copy
volume group (the Remote Copy volume group has not been recovered and is not
in a normal state). This process is considered a failback attempt without prior Remote
Copy volume group recovery.
HP 3PAR StoreServ Cluster Extension can detect the most current copy of your data
based on the Remote Copy volume group information. If HP 3PAR StoreServ Cluster
Extension detects that the remote HP 3PAR StoreServ Storage has the most current
data, it orders a resynchronization of the local disk from the remote disk, or it stops
the startup process to enable the cluster software to fail back to the remote HP 3PAR
StoreServ Storage.
