values: the initial copy pace, the max number of initial copy VOLs, the speed of the line between MCU
and RCU, and the number of lines.
The Cancel button cancels the registering RCU operation. The Set button sets the registering RCU operation
with the option you set on the RCU Option window.
NOTE: You cannot use the PPRC commands to change the RCU options. For more information on PPRC
TSO and ICKDSF commands, see ” Using PPRC commands for TrueCopy ” on page 157.

1. When you connect MCU with RCU without lines etc., specify 0.17[MB/ms] in “Speed of line between MCU and RCU.”
2. For “initial copy pace” in the formula above, see
Table 21 .
3. For the maximum number of initial copy volumes, see ” Initial copy operations ” on page 25. The default is 64.
4. Even if “Max number of initial copy VOLs”/“Number of lines between MCU-RCU” is larger than 16, specify “Max number of
initial copy VOLs”/“Number of lines between MCU-RCU” as 16.

1. When a PPRC command (TSO/ICKDSF) is used and the CU emulation type is 2105 or 2107 , the initial copy pace specified is
invalid. Therefore, the fixed value will be set.
