Creating TrueCopy for Mainframe Pairs
You can start establishing the TrueCopy for Mainframe pairs as soon as you have:
• Identified the volumes which will become the TrueCopy for Mainframe M-VOLs and R-VOLs
• Ensured that all system and TrueCopy for Mainframe requirements have been met
• Assessed TrueCopy for Mainframe Requirements
• Completed hardware and software installation
• Configured the MCUs and RCUs for TrueCopy for Mainframe operations
The Add Pair dialog box (see “Add Pair Dialog Box for Synchronous Pairs” (page 144) and “Add
Pair Dialog Box for Asynchronous Pairs” (page 145)) allows you to add new TrueCopy for Mainframe
pairs and set the initial copy options and pair options for the new pairs. To open the Add Pair
dialog box, click the Pair Operation tab, select a CU from the tree, select the desired device from
the list, right-click and click the Add Pair command. And then select the desired copy mode (sync
or async) for the new pair(s).
