Deciding on an Initial Replication Method
• Decide on the method to use to start replicating the data in the primary volume groups:
◦ Direct replication
“Deciding on an Initial Replication Method”
(page 53)
Copy data directly from the virtual volumes in the
primary volume group to the virtual volumes in the
secondary volume group.
◦ Via tape. Using tape for the initial backup can be faster if you are copying very large
volumes.
“Using Tape for Initial Synchronization and Backup”
(page 82)
1. Copy data in the virtual volumes in the primary
volume group to tape first.
2. To fully synchronize the primary and backup
systems, copy the data to the virtual volumes in
the secondary volume group.
Starting Initial Replication: Copying Data Directly from Primary Volume
Groups
1. On the primary storage system (System1), start replication for one of the primary volume
groups:
# startrcopygroup <group_name>
• <group_name> - Name of the primary volume group (for example, Group1).
The startrcopygroup command, when run on a group for the first time:
• Is mirrored from the primary system to the backup system (from System1 to System2)
• Begins copying the existing data from the primary volume group (Group1) to its associated
secondary volume group (Group1.r112)
2. To verify that the groups are synchronizing, issue the showrcopy command on the primary
system (System1).
# showrcopy
3. Wait until the SyncStatus column in the Group Information area displays Synced.
