I have a hardware indicator light illuminated on an HP Proliant ML350 G5 server that is running ESX 4.0.0, 164009. I wasn't the one who installed this server initially so I am not 100% sure what is loaded on it and what isn't loaded on it, plus I am new to supporting ESX or ESXi. Normally if I had a light on like this, I would go into the HP Systems Management page and have it tell me what component is failing. However, the Management Homepage isn't installed anywhere and I imagine that if it was it wouldn't be able to see any of the physical hardware of the server anyway. Can someone please advise me as to what I should do at this point to figure out what is causing this light as well as what I should do to be able to detect or anticipate hardware problems in the future? I saw the HP Systems Insight Manager product and that it might have support for managing the hardware of this machine, but it seems like a pretty big install just for what I want to do. Any advice that anyone could give on this issue would be greatly appreciated. Let me know if you need more info from me to assist.
