5-4 Chapter 5 Configuring Storage Systems and Logical Paths
Hitachi Universal Replicator for IBM /OS User’s Guide
5. Select the DKC radio button on the DKC Operation window to display the
Add DKC window. Set the S/N of the storage system which will be
connected, controller ID, path group ID, the initiator port in this storage
system, the RCU target port in the storage system which will be connected.
Operate at a primary storage system and a secondary storage system.
6. Select the Option button on Add DKC window, and then set the desired
options of local storage system. Operate at a primary storage system and a
secondary storage system.
7. Specify the journal group number from the Journal Operation window.
Register the journal volumes from the Edit JNL Volumes window. Operate
at a primary storage system and a secondary storage system.
8. Register the primary and secondary data volumes and the journal groups
that are paired from the Add Pair window in Pair Operation.
Note: URz pairs can only be registered by the primary storage system.
9. Exit the URz remote console software, and disconnect from the storage
system. Operate at a primary storage system and a secondary storage
system.
10. Repeat steps (3)–(9) for each storage system which will function as a URz
primary storage system. After you have configured the primary storage
systems, added the secondary storage systems, and configured the URz
options and journal groups, you are ready to begin URz volume pair
operations.
Setup Procedure (When More Than One Primary and
Secondary Storage System are Used)
1. Install URz on storage systems in the primary and secondary sites.
2. Make settings on ports and journal groups of the storage systems in the
primary and secondary sites.
For details on port settings for storage systems in the secondary sites, see
section
Configuring Paths and Ports to Establish Connections among
Secondary Storage Systems.
3. Create command devices in secondary storage systems.
4. Create remote command devices in the supervisor DKC, and then map
them to command devices in the subordinate DKCs.
For details on remote command devices to be created in the supervisor
DKC, see section
Creating Remote Command Devices to Establish
Connections among Secondary Storage Systems.
5. Create URz volume pairs.
6. With the remote command devices created in step
4, use the supervisor
DKC to register journal groups of secondary storage systems in an
extended consistency group.
