Use one of the following commands depending on the operation you want to perform:
cfgadm -c configure controller – configures a controller.
cfgadm -c unconfigure controller – unconfigures a controller.
In both commands, the controller refers to the controller number. For more information about the controller number, see About Attachment Point Identification.
The following example unconfigures the SCSI controller c2.
# cfgadm -c unconfigure c2
The following example shows the state of the c2 controller after it has been unconfigured. In the displayed information, the Occupant field indicates the controller's new state.
