Changing remote connection options

You can change the following remote connection options that affect how copy operations are performed:

  • Number of minimum paths for a pair. You can find detailed information in the planning section on minimum number of remote paths in the TrueCopy User Guide
  • RIO MIH Time, which is the interval for data transfer to complete.
  • Round trip time, which is the time limit for copying data to the S-VOL. For more information, see the planning section on round trip time in the TrueCopy User Guide for more information.
