Strange LED on drive

anything I don't mind · 1 May 2012 at 14:40

I have a hp 380 g6 i think it is. It had a faulty drive that is in a raid 5 configuration. I swapped the drive out and it rebuilt the array without any problems.

But since then there is a strange green LED that is always lit on the harddrive and the hp notes for led indicators does not have any info on a green led. anyone have any idea ?

it almost looks like the LED is extra bright and is causing the led next to it, to light up when it is not realy on. But it stays static constantly.

You don't have the indicator LED set on the iLO do you (if this is even there - same sort of thing as the blades/SANs)

I am not sure what you mean, what has the iLo got to do with the hard drive led? the led in question is the one with the red circle around it.

When i open the hp array management interface the LED's go blue.

I was thinking under the iLO you can light up LEDs to indicate drives etc., I was considering this an option although from what you say it seems they use blue LEDs as they do on their blades etc.

Quick Google for me doesn't reveal anything either

How about this.
I can't quite tell from the photo but 'The drive is online, but it is not currently active' seems likely.

Can you double check in the system management homepage and check it is definitely in the array?
I'm not sure if the disk would act like that, but is it possible that disk is set as a hot spare?

Another possibility is that the disk is set to 'identify', but I'm pretty sure that illuminates the blue LED, and only for a maximum of 1 hour.

Or it could just be a faulty LED on the disk, never seen one myself but not beyond the realms of possibility.

Yea that is the same hp page that i referred to when i said there appears to be no information on a solid green led. I am not sure about the hot spare vs in the array. The drive is definitely in use in the array, i watched it build and then complete and it now has no alerts on the controller and the drive is in the array. Well it definitely appears to be in the array. it looks exactly like the other array on the same controller.

Yes my thoughts were faulty LED my boss said i should swap out it, but i wanted to make sure first that it wasn't something else or a controller problem.

Basically the drive has a status of:

Online/Activity: ON

Fault/UID LED: green flashing regularly.

OK, I have just been too look again and i think I have been mistaken.

The led are as follows:

Online/Activity: Flashing irregularly

Fault/UID LED: flasing in unison with the other LED.

I am pretty confident that it was static before, but it is now flashing as normal with the other LED in the array. But I think what is causing the fault led to go green is that the online led is so bright that it is causing led bleed.

I will monitor this, thanks for your help .

Normally that LED is a solid when it is doing a rebuild of the array, but if you say its falshing now thats good
