The VMS enables you to remotely control identification LEDs on CNodes, DNodes and DBox drive slots. This is useful for matching up the physical components to their VMS IDs. The remote LED control feature is available in the VMS GUI. It enables you to turn on a LED and turn it off again. It also reflects the current LED status with a graphic representation of the LED that mimics the LED's state.

Identifying a CNode

  1. In the VAST Web UI, select Infrastructure from the menu and then Cnodes.

    The CNodes are listed.

  2. Click the Actions button (Actions_Button.png) for the CNode you want to identify and then select Led blink. After a few seconds, the LED icon in the LED Status column starts blinking.

    On the relevant CNode, the ID LED button for the CNode on the relevant CBox front panel is now blinking.

    There is also a blue LED that blinks on the rear panel of the CNode to help you identify the specific CNode.

  3. When you're done, click the Actions button again for the same CNode and select Led Off to stop the blinking.

Identifying a DNode

  1. In the VAST Web UI, select Infrastructure from the menu and then Dnodes.

    The DNodes are listed.

  2. Click the Actions button (Actions_Button.png) for the DNode you want to identify and then select Led on. After a few seconds, the LED icon in the LED Status column appears lit, indicating that the LED has been turned on.

    On the rear panel of the DNode, the ID LED lights blue. The LED lights up through the panel holes at the bottom right of the DNode front panel:

  3. When you're done, click the Actions button again for the same DNode and select Led Off to turn off the LED. After a few seconds, the LED icon and the ID LED on the DNode panel turn off.

Identifying a Drive Slot on a DBox

You can identify a slot via the Slots tab in the Infrastucture page that displays a list of slots, or from the Hardware Layout page that shows you a graphic representation of the DBox drive planes.

To identify a slot via the Infrastructure page:

  1. In the VAST Web UI, select Infrastructure from the menu and then Slots.

    The slots are listed.

  2. Click the Actions button (Actions_Button.png) for the slot you want to identify and then select Led on. After a few seconds, the LED icon in the LED Status column appears to turn on.

    The slot's IdentifyI LED turns on. The Identify LED for a given slot is the middle of the three LEDs to the left of the slot. The LED is always left of the slot that it identifies, whether the slot is on the left or the right of the DBox.

  3. When you're done, click the Actions button again for the same slot and select Led Off to turn off the LED.

To identify a slot via the Hardware Layout page:

  1. Select Hardware Layout to open the Hardware Layout page.

  2. Select a DBox from the dropdown list.

  3. Select Right View or Left View to show the slots on one side of the selected DBox.

  4. Select a slot by clicking on the image.

  5. In the panel on the right, click the LED Control button.

    The slot's IdentifyI LED turns on. The Identify LED for a given slot is the middle of the three LEDs to the left of the slot. The LED is always left of the slot that it identifies, whether the slot is on the left or the right of the DBox.

  6. When you're done, click the LED Control button again to turn off the LED.
