Important: Before you can create a Remote Mirror
Activating Remote Mirroring will log out any connections to controller host port 2, for both controllers in the storage subsystem, and reserve the port for mirror data transmission. I/O requests received on this port are accepted only from the remote controller owner of the other logical drive in the mirrored pair.
If you need to deactivate the Remote Mirroring feature at a later time, use the Storage Subsystem >> Remote Mirroring >> Deactivate menu option. For more information, see Deactivating the Remote Mirroring Premium Feature.
When you have activated Remote Mirroring on the primary and secondary storage subsystems, you are now ready to create Remote Mirrors. If you have not already created the primary logical drive
