Adding and Deleting Logical Paths to an RCU
Before adding a path to an RCU, make sure that the remote copy connection is
properly installed, the appropriate MCU ports are configured as initiator ports,
and the appropriate MCU CU is selected. You can add up to four RCUs to each
MCU CU and establish up to eight paths to each RCU. When you add a path to
an RCU, TrueCopy for z/OS will automatically start using the new path to
perform copy activities.
The Add Path dialog box (see Figure 5-4) allows you to add one or more paths
to an existing RCU. To open the Add Path dialog box, select the MCU&RCU
display on the RCU Operation window, select and double-click the desired
MCU CU in the tree, select the desired RCU, right-click the SSID and path list,
and then click the Add Path command.
