This command enables or disables the Rebuild Task Schedule defined for controller
/cx and sets the priority of rebuild versus I/O operations. When enabled, rebuild tasks will only be run during the time slots scheduled for rebuilds. If a rebuild is taking place when the schedule is enabled, it will be paused until the next scheduled time.
The priority of rebuild versus I/O operations is specified with 1..5, where 1 is more resources and 5 the least. Setting the value to 1 gives maximum processing time to rebuilds rather than I/O. Setting the value to 5 gives maximum processing time to I/O rather than rebuilds.
7000- and 8000-series controllers have only one setting for Task Rate; it applies to both rebuild and verify rates. This rate is not persistent following a reboot for 7000- and 8000-series controllers.
