The disk array automatically adjusts movement speeds in accordance with
the load state, minimizing the influence of moving operation to the business
system. A recommended moving speed is used, and this is selected by
default.
high
Data is copied in a maximum data transfer rate. Although this setting
completes moving process in a shorter time than "auto", it causes greater
influences to the business system. This setting is specified in a specific
case, such as a case where the system tuning takes precedence over business
operations.
Start Immediately

Start at Specified time
Starts logical disk movement operation at a specified time. Specifies time
of starting moving and time of continuing re-execution (time of continuing
retries if starting process fails). Starting time can be specified as late as 1
month later. Specifying up to 24 hours is allowed for continuing retries.
