2.2.2.1Configuration Policy Option
DR operations involve automatic hardware diagnosis to add or move a system board safely. Degradation of components occurs when the components are set according to the configuration of this option, and a hardware error is detected. This option specifies the range of degradation. Moreover, this option can be used for initial diagnosis by domain startup in addition to DR operations.
The unit of degradation can be a component where a hardware error is detected, the system board (XSB) where the component is mounted, or a domain.
This option is set using setdcl(8) command. Values that can be set and units of degradation is explained in TABLE
The default value of the configuration policy option is FRU.
