Hitachi Management Modules LED Test

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.

Target of the test : Hitachi Compute Blade

Agent deploying the test : An external agent
