   Device Tool (invoked on the command line as "devicetool") manages individual devices and displays configuration information.
   To start Device Tool, click once on its icon.  The devicetool command must be in your path for the tool to be successfully launched.
   Device Tool allows you to view information in several different ways.  This is controlled by the "Display" menu, located in the upper left corner.  The menu appears when you click the mouse "menu" button on the "Display" abbreviated menu button.  Selecting "all" displays all configured devices.  Selecting an equipment type from the "Display" menu displays configured devices of that type.  For example, selecting "tapes" displays all tape devices.  Selecting "configuration" displays configuration information.
   Selecting a device from the display allows you to perform appropriate actions on that device.  The possible actions are:  Change State, Unload, Audit, Label, Set Thresholds, and Set Maxcontig.  Device Tool makes available only those actions that make sense for the selected device.  Thresholds are set by using the sliders located at the bottom of the window; the new thresholds can be set by sliding the square along the slider, or by positioning the cursor in the field to the left of the slider, typing in a new value, and then pressing return.  The new thresholds are applied only when you click on the "Apply Thresholds" button.  Maxcontig is set in the same way as thresholds are set.  "Change State" is a menu button; clicking "menu" on this button displays the available states.  Choose a state by pulling the mouse down the menu until the desired state is highlighted.  All other actions (Unload, Audit, and Label) are performed by clicking once on the corresponding button.
   The display can be updated by clicking on the "Update" button, located in the upper right of the window.  The display will automatically update when you have specified a refresh rate (in the upper right corner) greater than zero and refresh is turned on.  Refresh is turned on when a checkmark appears in the box immediately to the left of "refresh"; clicking on this box toggles automatic refresh on and off; it is on by default.
