Initializing HDR with an external backup and restore

You can use external backups to initialize High-Availability Data Replication (HDR).

To initialize HDR with an external backup and restore:

Block the source database server with the onmode -c block command.
Externally back up all chunks on the source database server.
When the backup completes, unblock the source database server with the onmode -c unblock command.
Make the source database server the primary server with the following command: onmode -d primary secondary_servername
On the target database server, restore the data from the external backup with a copy or file-backup program.
On the target database server, restore the external backup of all chunks with the ontape -p -e command.
Make the target database server the secondary server with the following command: onmode -d secondary primary_servername
If the logical-log records written to the primary database server since step 1 still reside on the primary database server disk, the secondary database server reads these records to perform the logical recovery. Otherwise, perform the logical recovery with the ontape -l command.
The database server operational messages appear in the message log on the primary and secondary servers.
