HP 3PAR Cluster Extension Software Administrator Guide (5697-2047, June 2012)

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 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 Cluster Extension is unable
to create the online file and cannot bring the resource online.
Windows
If ApplicationDir is not set, HP 3PAR Cluster Extension uses the local
%HPCLX_3PAR_PATH% values as defined in the registry.
Default
values
Linux
online file: /etc/opt/hpclx3par
force flag: /etc/opt/hpclx3par/conf
Windows
%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 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 Cluster Extension can detect the most current copy of your data based on
the Remote Copy volume group information. If HP 3PAR Cluster Extension detects
that the remote HP 3PAR storage system 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 storage system.
If a resynchronization is ordered, HP 3PAR Cluster Extension monitors the progress
of the copy process. If the application service was running on a secondary HP 3PAR
storage system without a replication link, a large number of records may need to
be copied. If the copy process takes longer than the configured application startup
timeout value, the application startup will fail.
