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 –nocsus option to the paircreate command. The –nocsus
option creates a suspended journal volume, without copying the data. Figure 70 (page 420) shows

Site3.
