Chapter 3 Preparing for Universal Replicator z/OS Operations 3-63
Hitachi Universal Replicator for IBM /OS User’s Guide
Note: The steps to use data volume pairs in a system configuration that USP V
and TagmaStore USP/NSC are connected is the same with the steps to use
data volume pairs of USP V. For detailed information about the steps to use
data volume pairs, see
Manipulating Data Volume Pairs in Extended
Consistency Groups.
Connection with TagmaStore USP/NSC for 3DC Remote Copy
Configuration
USP V can execute remote copy in 3DC cascading configuration or 3DC multi-
target configuration by combining URz with TCz. USP V and TagmaStore
USP/NSC can be connected in 3DC cascading configuration or 3DC multi-target
configuration. When you connect USP V and TagmaStore USP/NSC, there are
no limitations for the combination of the primary and secondary sites.
Note: For detailed information about the 3DC cascading configuration, see
section
TCz Synchronous (3DC Cascading Configuration). For detailed
information about the 3DC multi-target configuration, see section
TCz
Synchronous (3DC Multi-target Configuration).
Connection with TagmaStore USP/NSC When Using Extended
Consistency Groups
URz can perform remote copy operations from more than one primary storage
system to more than one secondary storage system using extended
consistency groups. Primary storage subsystems can be a mixture of USP V
and TagmaStore USP/NSC. Secondary subsystems can also be a mixture of
USP V and TagmaStore USP/NSC storage subsystem. The mixture of primary
storage systems and the mixture of secondary storage systems are described
below.
Note: For detailed information about the extended consistency groups, see
section
Using Multiple Primary and Secondary Storage Systems.
• Mixture of USP V and TagmaStore USP/NSC primary storage systems
There are no limitations on the combinations of USP V and TagmaStore
USP/NSC primary storage systems. For details on connections between the
primary storage system and the secondary storage system, see the
previous section.
• Mixture of USP V and TagmaStore USP/NSC secondary storage systems
