Monitor drive shelf LEDs - NS224 shelves

You can monitor the health of your drive shelf by understanding the location and status conditions of the LEDs on your drive shelf components.

  • The location (blue) LEDs, on a shelf's operator display panel (ODP) and both NSM modules, can be activated to aid in physically locating the shelf that needs servicing: storage shelf location-led modify -shelf-name shelf_name -led-status on

    If you do not know the shelf_name of the affected shelf, run the storage shelf show command.

    Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command, but using the off option.

  • An LED state can be:

    • "On": The LED illumination is solid/steady

    • "Off": The LED is not illuminated

    • "Blink": The LED turns on and off at varying intervals depending on the FRU status

    • "Any state": The LED can be "On", "Off", or "Blink"

Operator display panel LEDs

The LEDs on the drive shelf front operator display panel (ODP) indicate whether your drive shelf is functioning normally or there are problems with the hardware.

The following illustration and table describes the three LEDs on the ODP:

drw ns224 odp leds IEOPS 1262
LED icon LED name & color State Description
drw sas power icon

Power (Green)

On

One or more power supplies are supplying power to the drive shelf.
drw sas fault icon

Attention (Amber)

On

  • An error occurred with the function of one of more shelf FRUs.

    Check event messages to determine corrective action to take.

  • If the two-digit shelf ID is also blinking, the shelf ID is in a pending state.

    Power cycle the drive shelf for the shelf ID to take affect.
drw sas3 location icon

Location (Blue)

On

The system administrator activated this LED function.

NSM module LEDs

The LEDs on an NSM module indicate whether the module is functioning normally, whether it is ready for I/O traffic, and whether there are any problems with the hardware.

The following illustration and tables describe NSM module LEDs associated with the function of a module and the function of each NVMe port on a module.

Power supply LEDs

The LEDs on an AC or DC power supply (PSU) indicate whether the PSU is functioning normally or there are hardware problems.

The following illustration and tables describe the LED on a PSU. (The illustration is an AC PSU; however, the LED location is the same on the DC PSU):
