due to error.

Copy Pace Number of tracks to be copied per remote I/O during the
operation. The default is 15. To change the copy pace,
enter a number from 1 to 4:
• 1 is slow. This setting limits the impact on host I/O to
maintain storage system performance.
• 2 and 3 is medium.
• 4 is fast. This setting increases the impact on host I/O
and might result in decreased storage system
performance.
If you enter a number from 5 to 15, the speed of 4 (fast
copy pace) is used.
