Setup Procedure
This section explains the procedure for setting up a 3DC multi-target configuration using TCz Synchronous
and URz.
To set up a 3DC multi-target configuration:
1. Install TCz Synchronous and URz. Configure ports and journal groups; journal groups must be
configured for storage systems in the three sites.
2. In the primary site, create a TCz Synchronous pair.
3. Wait until the status of the TCz Synchronous pair becomes Duplex.
4. In the primary site, create a URz pair.
When creating a URz pair, be sure to select a value from 1 to 3 as the mirror ID.
5. Wait until the status of the URz pair becomes Duplex.
If you want to create a URz pair for delta resync operation, go to the next step.
