Copy Pace

Specify the maximum number of tracks to be copied in a single remote I/O. The default is 15 (fast copy pace). To change the copy pace, enter a number from 1 to 4:

  • 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.

Select an ALUA mode.

  • Depends on Primary Volume Settings: The ALUA mode of the P-VOL is set.
  • Enabled: ALUA can be used for the LDEV.
