Setting the Asynchronous Copy Options
The Async Option dialog box (see “Async Option Dialog Box” (page 117) ) allows you to set and
modify the TrueCopy for Mainframe Async copy option parameters for the connected storage
system. To open the Async Option dialog box, right-click the CT groups and click Async Option
command.
The async options apply to the entire physical control unit, including all TrueCopy for Mainframe
M-VOLs and R-VOLs behind the control unit. The async options can only be modified when no
TrueCopy Async pairs or groups exist in the connected CU (M-VOLs or R-VOLs).

The CLPR(#) drop-down list allows you to specify CLPR ID. The default setting is 00.
The Pending Update Data Rate (%) option allows you to specify the TrueCopy for Mainframe Async
(and XP Continuous Access) sidefile threshold, which is the maximum amount of cache that can
be used for storing TrueCopy for Mainframe (and XP Continuous Access) Async recordsets (sidefiles).
You can select any value between 30% and 70% (10% increments). For further information on
sidefile inflow control, see
“Inflow Control of Recordsets” (page 23) .
The current pending update data rate is common to both TrueCopy for Mainframe and XP Continuous
Access operations. The most recently entered value (on the TrueCopy for Mainframe or XP
Continuous Access Option dialog box) will be applied to all TrueCopy for Mainframe Async
operations.
To set the async options:
