Log in to the external storage system and create a full LUN copy. The source LUN of the
LUN copy is the LUN of the external storage system and the target LUN is the
secondary LUN of the remote replication. Then start the LUN copy.
The full LUN copy is created and started. After the full LUN copy is complete, its
Running Status becomes Completed.
NOTE
In developer mode, run the create lun_copy remote name=test local_role=source lun_id=##
remote_device_id=## remote_lun_id=## is_target_lun_check=no command.
Delete the full LUN copy.
NOTE
In developer mode, run the change remote_replication clear_difference operation=recycle command.

command.
NOTE
In developer mode, run the change lun lun_id=## write_policy=write_back command.
The production center and the DR center have network established, remote storage
systems configured, and the primary and secondary LUNs created.
A LUN has been created on the external storage system. This LUN has the same capacity
as the primary and secondary LUNs of the remote replication.
The external storage system is in the production center and connected to the storage
system of the production center. The remote storage system has been configured in the
production center.
The external storage system is a Huawei product.
The production center supports the snapshot feature and both the production center and
the DR center support the LUN copy feature.
