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 HP 3PAR 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.

RESYNCWAIT

The online operation in the local cluster group must wait until the Remote Copy volume group status is no longer in syncing state. HP 3PAR Remote Copy initiates a resynchronization of the local virtual volume based on the remote virtual volume. HP 3PAR Cluster Extension monitors the syncing process. If no copy progress is made after configured ResyncWaitTimeout value, HP 3PAR Cluster Extension returns a global error. If RESYNCWAIT has been specified for the ApplicationStartup object, the ResyncWaitTimeout object must be specified, in case HP 3PAR Cluster Extension should wait for resynchronization changes for more or less than 90 seconds, which is the default.
