Hardware deconfiguration policies
You can set various policies to deconfigure processors and memory in certain situations.
Deconfiguration means that the resource is taken from a state of being available to the
system, to a state of being unavailable to the system. This can be automated to some degree
though the use of
policies.
You can enable policies that will deconfigure the processor when failures occur, such as a
predictive failure (for example, correctable errors generated by a processor exceeding the
threshold level for errors), floating point failure, functional failure of the processor, or system
bus failure.
Figure 10-52 shows the expanded Hardware Deconfiguration menu, which is a sub-menu
under the main System Configuration menu. Using this menu, you can:
򐂰 Set general hardware deconfiguration policies.
򐂰 Set processor deconfiguration policies.
򐂰 Set memory deconfiguration policies.

General hardware deconfiguration policies
You can use the panel shown in Figure 10-53 to set policies for much of the general system
hardware. You would select the policy that you want to enable or disable, and then click the
Save settings button to make the change.
