Delta Resync Pair

The Delta Resync pair must be configured when using 3DC Tri-Link configuration. The Delta Resync pair must be created with the –nocsusoption to the paircreate command. The –nocsusoption creates a suspended journal volume, without copying the data. Figure 70 (page 420) shows an example 3DC Sync/CAJ replication using Delta Resync pair configured between Site2 and Site3.
