HP P6000 Cluster Extension Software Administrator Guide (5697-0986, June 2011)

• 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. If you want to use P6000 Cluster Extension
capabilities to recover a suspended DR group state during a failover,
make sure that subsequent failover operations are disabled in case
the recovery attempt fails. To disable subsequent failover attempts,
set the FailoverThreshold to zero (0) until the recovery operation has
finished successfully.
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 P6000 Cluster Extension reports a data center error. Depending on the cluster
software, the application service cannot start on any system in the local data center,
and the cluster software transfers the application service back to the remote data
center. Use this value to provide the highest level of application service availability.
In a two-node cluster, this process does not work because the target failback system
is not available. In this case, the application service must be started manually, or
the ApplicationStartup object must be set to RESYNCWAIT.
FASTFAILBACK is not available when the UseNonCurrentDataOkLinkUp property
is set to YES.
RESYNCWAIT
The online local cluster group must wait until the DR group status is no longer mer-
ging or copying. P6000 Continuous Access initiates a resynchronization of the
local vdisk based on the remote disk. P6000 Cluster Extension monitors the copy
process. If no copy progress is made after a monitoring interval expires, the copy
process is considered failed and P6000 Cluster Extension returns a global error.
If RESYNCWAIT has been specified for the ApplicationStartup object, the Resyn-
cWaitTimeout object must be specified, in case P6000 Cluster Extension should
wait for resynchronization changes for more or less than 90 seconds, which is the
default.
Files resource_name.forceflag
resource_name.online
If specified in a user configuration file, resource_name is the value of the APPLIC-
ATION tag; otherwise, resource_name is the value of the P6000 Cluster Extension
resource name.
ClusterNotifyCheckTime
Format Integer
Description Specifies how often P6000 Cluster Extension will check for VM live migration state
changes.
