Writing a Device Method
Device methods are programs associated with a device that perform basic device configuration operations. These operations consist of defining, undefining, configuring, unconfiguring, and reconfiguring a device. Some devices also use optional start and stop operations.
The following are the basic device methods:
Item | Description |
---|---|
Define | Creates a device instance in the Customized database. |
Configure | Configures a device instance already represented in the Customized database. This method is responsible for making a device available for use in the system. |
Change | Reconfigures a device by allowing device characteristics or attributes to be changed. |
Unconfigure | Makes a configured device unavailable for use in the system. The device instance remains in the Customized database but must be reconfigured before it can be used. |
Undefine | Deletes a device instance from the Customized database. |
