12 Setting Up a Bidirectional Configuration
“Considering Requirements and Restrictions” (page 23)1. Verify that your setup plan meets the Remote Copy
requirements.
“Example Bidirectional Setup” (page 76)2. Acquaint yourself with the basic bidirectional setup.
“Setting Up a Unidirectional Configuration” (page 67)3. Set up the unidirectional configuration for the Remote
Copy pair.
4. Set up the bidirectional configuration for the Remote
Copy pair:
“Setting Up the Systems for Bidirectional Remote Copy”
(page 77)
a. Ensure the primary and backup systems are set up.
“Creating Volume Groups for Bidirectional Remote Copy”
(page 78)
b. Create primary volume groups on the new primary
system (the system that functions as the backup system
in the unidirectional configuration).
c. Start the initial data replication:
“Starting Initial Replication: Copying Data Directly from
Primary Volume Groups” (page 80)
• To copy data directly from the primary to the backup
system:
“Using Tape for Initial Synchronization and Backup”
(page 82)
• To copy data first to tape and then from tape to the
backup system:
Example Bidirectional Setup
The bidirectional setup steps refer to the example setup illustrated in Figure 23 (page 77):
