2 Identify LED
3 Node status LED

5 Battery status LED

Power LED

The green power LED indicates one of the following power conditions.

Off

One or more of the following are true:

No power is present at the power supply input.
The power supply has failed.
The LED has failed.

On

The node is turned on.

Blinking

The node is turned off, but is still connected to a power source.

Power button

The power button turns main power on or off for the SAN Volume Controller .

To turn on the power, press and release the power button.
To turn off the power, press and release the power button. For more information about what to check before you turn off the SAN Volume Controller node, see MAP 5350: Powering off a node.

Attention: When the node is operational and you press and immediately release the power button, the SAN Volume Controller writes its control data to its internal disk and then turns off. This process can take up to 5 minutes.

Identify LED

This LED blinks if the Identify button on the back of node is pressed. The Identify LED blinks on both the front and rear panels. Use this feature to find a specific node in the data center. After the SAN Volume Controller system is initialized and initial setup is completed, you can use the Management GUI to identify a node by making the Identify LED on the node blink.

Node status LED

The green Node status LED has the following states:

Off: The SAN Volume Controller software is not running or cannot communicate with this LED.
On: This node is active in a SAN Volume Controller system.
Slow blink: This node is not active. It has Candidate or Service status.
Fast blink: The node is dumping cache and state data to the local disk in anticipation of a system reboot from a pending power-off action or other controlled restart sequence.

Node fault LED

The yellow Node fault LED has the following states:

Off: No warning or critical error is shown in the baseboard management controller (BMC) event log, and no fatal node error is reported by the SAN Volume Controller software.
On: The SAN Volume Controller software indicates a fatal node error.
Blinking: A warning or critical error is shown in the BMC event log.

Battery status LED

The green battery status LED has the following states:

Off: Hardened data is not saved if there is power loss or the SAN Volume Controller software is not running.
On: Battery charge level is sufficient for the hardened data to be saved twice if power to the node is lost.
Slow blink: Battery charge level is sufficient for the hardened data to be saved once if power to the node is lost.
Fast blink: Battery charge level is too low for the hardened data to be saved if power to the node is lost. Batteries are charging.
