ports. Initiator mode emulates a host channel, enabling the MCU to send write I/O operations
directly to the RCU target port. Use XP Continuous Access to change the configuration of the ports
as needed to accommodate host and XP Continuous Access communications paths. Two or more
Initiator ports must be configured before you can register RCUs and create XP Continuous Access
pairs. For further information, see
“Initiator ports and RCU target ports” (page 11)
Use the Port tree and Port list on the RCU Operation pane to configure MCU ports. Clicking Port
in the Switch Display box changes the tree to the Port tree and changes the list to the Port list.
1.
In the XP Continuous Access main pane, click RCU Operation.
2.
Click Port in the Switch Display box. The tree changes to the Port tree and the list changes to
the Port list.
3.
Click a package or port type from the Port tree. Only the selected package or port type appears
in the Port list.
4.
Click the ports of the CU you want to configure as MCUs from the Port list, right-click, and
click Initiator.
For port change operations, there is no separate pane. The list keeps displaying the Port list. For
more information about changing the port mode, see
“Port change operation” (page 80)

RCU operations
RCUs are control units that control S-VOLs of volume pairs. RCUs are connected to MCUs via
remote copy connections, and receive and process commands from MCUs.
RCU operations are performed separately for each CU image of each MCU and RCU to provide
maximum flexibility in XP Continuous Access configurations. The following are RCU operations:
•
Viewing RCU Status (RCU Status)
•
RCU options apply to all CU images of the MCU.
•
Modifying RCU options (Change RCU Option)
•
“Deleting RCUs (Delete RCU)” (page 76)
•
“RCU path parameters ” (page 76)
•
Adding and deleting logical paths for RCUs (Add Path/Delete Path)
•
Adding and deleting SSIDs for RCUs (Add SSID/Delete SSID)
Use the RCU Operation pane to perform RCU operations. All operations that can be performed
from the RCU Operation pane have the following common procedure:
1.
Click the CU number or Package number in the tree.
2.
Click one or more RCUs or Packages in the list. For registering RCU operation, the RCU does
not have to be selected. For this step, the list can be blank.
3.
Right-click the list, and perform one of the following:
a.
Click MCU&RCU in the Switch Display box to display the following commands:
•
RCU Status: Displays RCU status
•
RCU Operation: RCU settings operation
•
Edit SSID(s)&Path(s): SSID and Path settings operation
When the list is blank, only the RCU Operation command can be activated.
b.
Click Port in the Switch Display box to display the following commands:
•
Initiator, RCU Target, and Target for fibre
•
RCP and LCP for serial (see
“Port change operation” (page 80)
