Modifying RCU options (Change RCU Option)

Use the RCU Options pane to modify RCU options set when you registered the RCU. When the RCU
Option pane is opened with the Change RCU Option command, all fields are blank. You must fill in the
fields you need to modify; it is not necessary to fill in all fields. Fields left blank keep settings made for the
registering RCU operation.
RCU options apply to all CU images of the current MCU and all RCUs connected to the MCU.

For further information about the RCU Option pane, see
1. In the CU number/Port tree on the RCU Operation pane, ensure that the correct CU image is selected.
2. From the MCU/RCU list, click the RCU you want to modify.
3. Right-click, click RCU Operation, and click Change RCU Option. The RCU Option pane appears.

RCU Settings Parameter list (RCU Option)

• S/N and SSID: RCU serial number and SSID
• M-R Path: Channel type
• Min.Path: Minimum number of paths required for each RCU connected to the current MCU
• Activity: Number of concurrent initial copy operations
• MIH Time: Time value for the remote I/O (RIO) missing interrupt handler (MIH)
• Path Watch: Time for monitoring blockade in the Fibre Channel paths on the MCU side

Deleting RCUs (Delete RCU)

You can delete an RCU from an MCU only after all Continuous Access XP volume pairs between the MCU
CU image and RCU CU image are deleted. When you delete an RCU from an MCU, the MCU deletes all
logical paths from the current MCU CU image to the selected RCU CU image. Deleting an RCU does not
affect Continuous Access XP operations between other MCU CU images and that RCU. After an RCU is
deleted, reconfigure remote copy connections to add another RCU to the MCU, or remove remote copy
connections and reconfigure MCU ports (initiator ports to ordinary target ports for fibre, RCPs to LCPs for
serial) to provide additional host channels for the MCU.
After being set, options can be modified and canceled (see
settings" on page 77).
