Re: Disk red led

Hm...for the second question: NO.
It is very strange.
Did you try to use "ioscan -fnC disk" command?
Every disk in CLAIMED status?
Can you list the device file with "lssf " command?
If everything is OK. Then can you reboot the server? I think that trouble will be solved.
I do not know but a long time ago, my server had the same trouble. And I call to HP to get support.
They can not find the exactly the result. Very strange: the red LED disappear when reboot my server?

Re: Disk red led

I discovered the same sort of problem on an rp3440 (Same hardware chassis) last week at a customer.

There was a hardware intervention from HP when I was not there, but the problem is solved now.

This is what the person of HP has written on his report

These is an current issue!
Bend middle rail slot!

Re: Disk red led

Yes, let try and please tell me the result.
Because, as you said:
Bend middle rail slot! That disk may broken!

You can try this command:
ioscan -f

Is there any trouble?

OK! I am waiting for you. :)

Re: Disk red led

SOLUTION:

1. REMOVE ALL disk (internal) from server rx2600.
2. Unplug TWO (all) power supplay
3. wait for a minute
4. Replace all disk (in ther original slot)
5. Plug PS
6. Start Server form GSP

It's all

For me that work fine !

Tnks for all !!

Re: Disk red led

First off, this is an educated guess based on my knowledge of other scsi devices. I am not certain that this will apply to A9897A drives, but in my experience SCSI LED errors tend to point to the same general issue.

In my experience, a RED LED that goes GREEN with disk activity has always meant one of 2 things:
1) There is a power fault somewhere in the system that is causing the SCSI disk to get "dirty" power.
2) The disk is getting too hot.

Hope this helps

Re: Disk red led

Andy,

I think, that in my case red let is switch on from disk back plane.
1. There isn't a power fault, other disk work fine and problem disk work fine on other slot.
2. Env is ok.

Q4you,Sunilkumar

My boss never forgot about red let :(

Jimkery,

For me it wasn't funny :) pls believe me.
I'm sure that disk plane remind some disk problem and funny part is that you can not switch this warning of and event you put new disk it still remaind you that in that slot was problem.
I have same situation with PS again over rx2600.


tnks all.
