Hi again,
I think I'm going to tell you how to do this via commandline (the GUI is for wimps).
ssh to your HMC as hscroot, then:
A) To list the various LED states issue
1) for the physical managed system (I'll call it managed_system, please replace with your actual name)
lsled -m managed_system -r sa -t phys
2) for the virtual partitions
lsled -m managed_system -r sa -t virtuallpar
Output will be
state=off or state=on
(for -t virtuallpar accompanied by lpar id and name)
B) To change the state of an attention LED to "off" issue
1) for the physical managed system
chled -m managed_system -r sa -o off -t phys
2) for a virtual partition (I'll call it partition_name, please replace with your actual name)
chled -m managed_system -r sa -o off -t virtuallpar -p partition_name
Since you worked on the hardware, it's surely the "physical" LED which is affected in your case.
