Table 5.6 Cache Flush on Selected Controller (Cont.) Description Flushes the controller cache on the selected controller(s). 5.4.5 Set Controller Properties This command sets the properties on the selected controller(s). For example, for {RebuildRate -val}, you can enter a percentage between 0 percent and 100 percent as the value for the rebuild rate. (The rebuild rate is the percentage of the compute cycles dedicated to rebuilding failed drives.) At 0 percent, the rebuild is done only if the system is not doing anything else. At 100 percent, the rebuild has a higher priority than any other system activity. Note: Lenovo recommends the default rebuild rate of 30 percent, and the default patrol read rate of 30 percent. Use the command in Table 5.7 to display the list of properties you can set for the controller(s).
