Set the Control State of a Device Online or Offline

An offline device is unavailable to hosts. Take a device offline before removing it from the library.

  1. Click Hardware in the left navigation area of the GUI. Locate the device in the device tree.

  2. Select the device and then from the Actions drop-down (or right-click menu) select Control State, and then click Go Online or Go Offline.

    Note:

    Some devices (such as drives and robots) will complete in-process jobs before going offline. When this occurs, the GUI indicates "offline pending" for the device.

What's the Difference Between Control State and Location State?

The control state indicates the current online or offline state of the device. The location state (either Bring Online or Keep Offline) determines whether the library should bring the device in that slot online when you insert a new device or when the library powers on.
