I have one P550 running VIOS with a couple of LPARs.
Recently I needed to switch a power supply, the business were not prepared for the machine to be powered down, so the switch was made with the machine up and running. Of couse this caused the Amber System Attention LED to iluminate on the front of the machine.
I am familiar with clearing this on a P-series running just AIX. I can go into diag, tasks, Identify and attention Attention Indicators.
On VIOS for a specific LPAR the task would appear to be even easier. For any LPAR with a system Attention LED set this is shown on the Integrated Virtualization Manager (IVM). Select an LPAR, properties and set system Attention LED to inactive.

However the System Attention LED is active on the Machine and in the System Overview shown in the IVM. It is in a layer below.
How do I clear the System Attention LED from the System Overview?
VIOS itself is an LPAR so logging in as padmin , and attempting to clear the LED through diag will not work!

P.S. I do not have a HMC.
I only have the IVM available to me.
Is it possible to clear the light using the 3 buttons and the pannel on the front of the machine??

I have the same LED on. I have cleared it before but dont remember how I did it. The box had to be moved in the Data Center and now the light is on.

Thanks

This is actually surprisingly easy.

Log on to the VIOS partition padmin account.
There are 2 commands which enable you to do this:
lsled and chled - surprisingly these are not listed if you type help from the padmin promp, which lists most of the commands you can use.

Make sure you have clear LEDs on the all the LPARs including the VIOS LPAR
$ lsled -r sa -t virtuallpar
lpar_id=1,lpar_name=yourvios_vios,state=off
lpar_id=2,lpar_name=your_lpar1,state=off
lpar_id=3,lpar_name=your_lpar2,state=off

If not sort these out properly as you do under AIX. What ever caused light to come on resolve it. We notice though that sorting these wont always clear the LED on the physical machine but if everythings cleared , all virtual lpar system indicators are off and the physical machine LED is still on proceed as follows:

$ lsled -r sa -t virtualsys
state=on

You will probably see state=on
Also try

$ lsled -r sa -t phys
state=on

Again this will show state on.

Now clear the virtualsys LED as follows

$ chled -r sa -t virtualsys -o off

Now try:

$ lsled -r sa -t virtualsys
state=off

Also try

$ lsled -r sa -t phys
state=off

The physical light most likely will become off too when you changed the virtual LED. Well it did for me anyhow.

just type chled or lsled without parameters for help on the commands.

Let me know if this works.

you ROCK!!
Thanks. The light is off now. I dont remember doing it that way before. It is off now.
This will not disable the LED just in case there are issues later right?

Thanks again

SeaCros,
You cannot disable the LED, it will come on if there is a reason.
The service processor (FSP) "owns" the LED and will turn it on any time it likes.
The errors you see in AIX or VIOS / IVM also come from the FSP, so you have nothing to worry about there.
