6 For Copy Pace, specify the number of tracks to be copied during the
.
initial copy. The default is 15 (fast copy pace). To change the copy pace,
enter a number from 1 to 4. This option affects performance as follows:
The speed of 1 is a slow copy pace, and is used to reduce impact on
¢
host I/O.
The speeds of 2 and 3 are a medium copy pace.
¢
The speed of 4 is a fast copy pace, and the host I/O performance
¢
might be degraded.
If you enter a number from 5 to 15, the speed of 4 (fast copy pace) is
used.
