Use this dialog box to configure the DR group behavior.
• The values you can configure depend on whether the DR group uses synchronous or
enhanced asynchronous mode.

the EVA Continuous Access link is up.
• The settings in the Replication link down scenario section affect the failover behavior when
the EVA Continuous Access link is down.
2. Select YES or NO as the Use non-current data OK value in the Replication link up scenario

This value is available only for enhanced asynchronous DR groups. For more information, see
