To configure or unconfigure a controller, use the following commands:
To configure a controller: cfgadm -c configure controller
To unconfigure a controller: cfgadm -c unconfigure controller
In both commands, 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. The Occupant field in the output indicates the controller's new state.
