Hitachi Universal Replicator for IBM /OS User’s Guide
USP V storage system in the TCz Synchronous secondary site:
– The USP V storage system must have TCz Synchronous installed.
– The USP V storage system must have URz installed.
– The USP V storage system must have TCz Synchronous secondary
volume. Note: This volume will be used for creating a URz pair when
disaster recovery is performed at the primary site.
– The USP V storage system must have URz master journal volume.
Note: This volume will be used for creating a URz pair when disaster
recovery is performed at the primary site or when you create a URz pair
for delta resync operation.
– If you use Business Continuity Manager, you need to make settings on
the storage system. Please refer to the Business Continuity Manager
User's Guide for information about settings required for volume
operations in remote sites.

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.
5. When creating a URz pair, be sure to select a value from 1 to 3 as the
mirror ID.
6. Wait until the status of the URz pair becomes Duplex.
7. If you want to create a URz pair for delta resync operation, go to the next
step.
