To modify the RCU option:
1.
From the CU Number tree on the RCU Operations window, verify the correct CU image is selected.
2.
From the MCU/RCU list on the RCU Operations window, select RCU whose options you want to
modify.
3.
Right-click to display the pop-up menu, click RCU Operation, and then click Change RCU Option. The
RCU Option window is displayed.
4.
From the RCU Option window, modify the RCU options. When the RCU Option window is opened, all
the boxes display the current settings. Complete the boxes with the RCU options you want to modify.
5.
Click Set to set the changes you made. The list changes to the RCU Settings Parameter list (RCU
Option). To cancel all the changes you made, click Cancel.

Deleting an RCU (Delete RCU)
You can delete an RCU from an MCU only after all TC390 volume pairs between the MCU CU image and
RCU CU image have been 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 the
TC390 operations between the other MCU CU images and that RCU. After an RCU has been deleted, you
can reconfigure the remote copy connections to add another RCU to the MCU, or you can remove the
remote copy connections and reconfigure the MCU ports (RCPs to LCPs for serial; initiator ports to ordinary
target ports for fibre) to provide additional host channels for the MCU.
Use the Delete RCU command to delete the selected RCU from the current MCU CU image. If all affected
pairs have not been deleted, the MCU will reject the delete RCU operation to prevent accidental deletion of
TC390 pairs.
To delete an RCU from an MCU:
1.
Connect to the MCU.
2.
Verify that all affected TC390 volume pairs have been deleted. The volume pairs that consist of a
M-VOL in the connected MCU and CU image and an R-VOL in the selected RCU must be deleted.
3.
From the CU number/Port tree on the RCU Operations window, verify the correct CU image is selected.
4.
From the MCU/RCU list on the RCU Operations window, select the RCU that you want to delete.
5.
Right-click to display the pop-up menu, click RCU Operation, and then click Delete RCU.

Click Apply on the TrueCopy main window.
Adding and deleting logical paths for an RCU (Add Path and Delete Path)
Before adding a path to an RCU, verify that the remote copy connection is properly installed, that the
appropriate MCU ports are configured as RCPs (serial) or Initiator ports (fibre), and that the appropriate
MCU CU image is selected. You can add up to four RCUs to each MCU CU image and establish up to
eight paths to each RCU. When you add a path to an RCU, TC390 will automatically start using the new
path to perform TC390 copy activities.
