The fault light of the controller is off

[weiliu]

Hello:
When I am checking the device, the controller fault indicator is on. After I check the device on the CLI, no alarm is found. How do I determine the cause of the controller fault indicator? Can I turn it off with a command?

Helli Weiliu,

- What  Hardware model of Netapp are you working on with what version of OS?

- If is it ONTAP, you can run the following commands to check which exact component had the amber light.

::> set adv
::*> system controller fru led show

- You have to verify the EMS logs and any other related logs for that component to understand the reason for it.
- Below command will turn of the fru in most cases.

::*> system controller fru led modify -node <node> -fru-id <fru_type, e.g. dimm> -fru-slot <slot#> -fru-state off

Note: The amber light may reappear if the issue is still there.
