Measures reported by HBladeMgtModLEDTest

Each management module of the target Hitachi Compute Blade is provided with a set of LEDs to visually notify the administrators on the functioning of the management module. The following LEDs are available in each management module:

  • Heartbeat LED flashes green light when the management module works normally

  • Power LED notifies power-on and power-off status of the management module

  • Identify LED is manually turned on by the administrators for visually locating the management module

  • Alarm LED flashes red light when the errors or redundant failures occur

  • Primary LED indicates whether/not the management module is currently active

  • Remote LED indicates whether/not the management module is accessed remotely

With the help of these LEDs, administrators can easily figure out the health and working mode of the management module at a single glance. If the LEDs fail, administrators may not be notified to critical issues of the management module. This may result in the failure of the management module and if left unattended may cause irreparable damage to the target Hitachi Compute Blade. Therefore, it is imperative to replace the faulty LEDs. The Hitachi Management Modules LED test aids administrators to monitor the status of the LEDs and figure out the LEDs that are faulty.

This test auto-discovers each LED in the management module, and reveals the current status of the LED and color of the LED.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Led_Status Indicates the current status this LED.   The values that this measure can report and the numeric values they indicate have been listed in the table below:

State Numeric Value
Turn Off 1
Turn On 2
Unknown 3
Blink 4
Blink Fast 5
Blink Slow 6

Note:

By default, this measure can report the Measure Values mentioned above while indicating the current status of the LED on the management module. However, the graph of this measure is indicated using the numeric equivalents.
Led_color Indicates the color emitted by this LED.   The values that this measure can report and the color they illuminate have been listed in the table below:

Color Numeric Value
Blue 1
Green 2
Red 3
Amber 4
Unknown 0

Note:

By default, this measure can report the Colors mentioned above while indicating the color of the LED. However, the graph of this measure is indicated using the numeric equivalents.
