Selecting an Initial Replication Method for M-to-N Remote Copy
Select the method to use to start replicating the data in the primary volume groups:
•
Direct replication
“Selecting an Initial Replication Method for M-to-N
Remote Copy” (page 54)
Copy data directly from the virtual volumes in the
primary volume group to the virtual volumes in the
secondary volume group.
•
Through 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 151)
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.
NOTE:
The admitrcopyvv command provides a -nosync option that specifies that the volume
should skip the initial synchronization. This is for the admission of volumes that have been pre-synced
with the target volume. By default, a full synchronization is performed on added volumes unless
the -nosync option is specified. For more information, see the HP 3PAR Command Line Interface
Reference, which is available on the HP Support Center (HP SC) website:
Starting Initial Replication for M-to-N Remote Copy
Follow these steps to copy data directly from the virtual volumes in the primary volume group to
the virtual volumes in the secondary volume group:
1.
On the primary storage system (System1), start replication for one of the primary volume
groups by issuing the following command:
# startrcopygroup
where
The startrcopygroup command, when run on a group for the first time:
•
Is mirrored from the primary system (System1) to the backup system (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.
