10 Setting Up Synchronous Long Distance Remote Copy
“Considering Requirements and Restrictions” (page 23) 1. Verify that your setup plan meets the Synchronous Long
Distance requirements.
“Example Synchronous Long Distance Setup” (page 56) 2. Acquaint yourself with the Synchronous Long Distance
setup.
“Verifying Connectivity between Systems” (page 58) 3. Verify connectivity between the Remote Copy pairs you
plan to configure.
“Setting Up the Primary System” (page 59) 4. Set up the primary and backup systems (the Remote
Copy pairs) and check the links.
“Setting Up the Backup Systems” (page 59)
“Checking the Links between Systems” (page 61)
“Verifying Virtual Volumes Are Created for Remote Copy”
(page 62) 5. Make sure the virtual volumes you plan to replicate with
Remote Copy already exist.
“Creating Volume Groups for Synchronous Long Distance
Remote Copy” (page 62) 6. Create the volume groups.
“Starting Initial Replication: Copying Data Directly from
Primary Volume Groups” (page 65) 7. Start the initial data replication.
When you configure Remote Copy systems, you create a target definition on each system. This
target definition is used to identify the other system (the target system) in the Remote Copy pair;
for example, the primary system’s target system is the backup system. For more information, see
“Remote Copy Pairs and Targets” (page 181) .
Synchronous Long Distance Remote Copy configurations consist of two Remote Copy pairs: one
primary storage system that targets and replicates data to two backup systems.
Example Synchronous Long Distance Setup
The setup steps for Synchronous Long Distance configuration refer to the example setup illustrated
in
Figure 21 (page 57) .
