Setting up remote paths

If you use Continuous Access Asynchronous, Continuous Access Synchronous, or Continuous Access
Journal to replicate volumes, you must set up a logical path (called a remote path) to link the MCU
(or primary DKC) of the local storage system to the RCU (or secondary DKC) of the remote storage
system. You can set up a remote path by starting the wizard that is available under the Remote Paths
tab of the Storage Systems view.

About remote paths

Remote Paths are port connections between local and remote storage systems. These logical routes
are used by remote copy pairs for copying data from a P-VOL to an S-VOL. Replication Manager
allows remote path configuration for different replication technologies. You must set up a remote path
before you can use any of the following volume replication functions:

Continuous Access
Based on the copy direction, you specify the port for the local storage system CU (MCU) and the
port for the remote storage system CU (RCU).

Initiator

and

RCU Target

are set automatically

as the attributes of the specified ports. You can specify either CU Free (to connect only from the
local storage system to a remote storage system using a dynamically assigned MCU-RCU pair) or
CU Specific (to connect each path using a specified MCU and RCU).

Continuous Access Journal
Using CU Free, you can specify the port for the local storage system and the port for the remote
storage system. You must set paths for both directions.

Initiator

and

RCU Target

are set

automatically as the attributes of the specified ports.

An open system is being used.

The storage system type is XP12000/XP10000/SVS200 or XP24000/XP20000.

The version of the Device Manager server used as an information source is 6.1 or later.
