HP 3PAR StoreServ Cluster Extension Software Administrator Guide

Use this dialog box to configure the Remote Copy volume group behavior.
• The settings in the Replication link up scenario section affect the failover behavior when
the HP 3PAR Remote Copy link is up.
• The settings in the Replication link down scenario section affect the failover behavior
when the HP 3PAR Remote Copy link is down.
2. Select RESYNCWAIT or FASTFAILBACK for the ApplicationStartup behavior.
If you selected RESYNCWAIT, set the RESYNCWAIT timeout value in seconds.
3. Select YES or NO as the UseNonCurrentDataOk value in the Replication link down scenario
section.
4. Select YES or NO as the Auto sync data to third DC value in the 3DC configuration
section.
NOTE: This option is enabled only for the 3DC RemoteCopy group. In a 2DC RemoteCopy
group, the Auto sync data to third DC option is disabled.
If YES is selected, then CLX starts the RC group and automatically syncs with the local periodic
group after the RC group Failover and Failback between DC-A and DC-B data centers.
If NO is selected, you must manually start and sync the data from the current primary datacenter
to the remote/third [DC-C] datacenter after the failover/failback operations between DC-A
and DC-B datacenters. CLX will not start and sync the data to remote/third [DC-C] datacenter
automatically.
For more information on HP 3PAR CLX 3DC, see “HP 3PAR 3DC (3 Datacenter) environment”
(page 80).
5. Enter the path of the application directory. The application directory is where HP 3PAR
StoreServ Cluster Extension searches for application-specific files, such as the force flag or
online file.
