HP XP Cluster Extension Software Administrator Guide

If ApplicationDir is set to a nonexistent drive and PairResyncMonitor is not enabled,
HP XP Cluster Extension is unable to create the online file and cannot put the resource
online.
Windows
If ApplicationDir is not set, HP XP Cluster Extension uses the local %HPCLX_PATH%
values as defined in the registry.
Default
values
%HPCLX_PATH%
Files resource_name.forceflag
resource_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 XP Cluster
Extension resource name.
ApplicationStartup
Format String
Description (Optional) 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 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 disk set (the disk pair has not been
recovered and is not in PAIR state). This process is considered a failback attempt
without prior disk pair recovery.
HP XP Cluster Extension can detect the most current copy of your data based on the
disk state information. If HP XP Cluster Extension detects that the remote disk array
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 disk array.
If a resynchronization is ordered, HP XP Cluster Extension monitors the progress of
the copy process. If the application service was running on a secondary disk array
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.
MSFC
If the ApplicationStartup resource property is set to FASTFAILBACK and the
FailoverThreshold value is set to a number higher than the current number of clustered
systems for the service or application, the service or application will restart on
configured nodes until one of the following conditions is met:
• The resource is brought online in the remote data center.
• The resource failed because the FailoverThreshold value has been reached.
• The resource failed because the FailoverPeriod timeout value has been reached.
CAUTION: Disable subsequent automated failover procedures for recovery failback
operations.
Valid values FASTFAILBACK (default)
The cluster group is brought online in the remote data center (if possible) without
waiting for resynchronization. The application startup process is stopped locally and
