2.2.2.1
Configuration 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
The default value of the configuration policy option is FRU.
