Changing the Utility Priority

This function allows the user to change the priority at which all utilities (Verify, Reconstruct,

Expand, Initialize, etc.) run when there are active I/O operations competing for the controller's

CPU. The choices are:

High (Default)
Medium
Low

For example, select High if the highest priority is to get the array back to a fully fault-tolerant

state. This causes heavy I/O with the host to be slower than normal. Select Low if streaming

data without interruption (such as for a Web server), is more important than data redundancy.

This allows the Reconstruct (or other utility) to run at a slower rate, with minimal effects on

the host I/O.

To change the utility priority:

Select Configuration Menu from the System Menu and press Enter.
The Configuration Menu should now display (Figure 31).

Select Utility Priority and press Enter.
The Utility Priority screen will display (Figure 71).
The current setting is marked with an * next to it.
