I bought a HP ProLiant DL160 G5 off eBay some time ago for use as a file server for a LAN party group (specifically I was after something with four 3.5" bays on the front) - but it turned out to be not powerful enough for my needs (iSCSI) so I upgraded. I now wish to sell it on eBay again but the license on the ILO, I found out, wasn't exactly... legit. I don't want to get into trouble for what the last guy did, is there any way to clear this license?
You don't really need to remove the ILO license. Nobody is going to care, and HP isn't interested in auditing the license status of such an old server.
But if you can open an SSH connection to the ILO using username:
Administrator, just run:
delete /map1 license
That's all you'll need.
Edit: My mistake. This server is a ProLiant DL160 G5, so it doesn't even use a full-featured ILO2, but rather an embedded Lights-Out 100i. This requires a different approach:
My opinion is that you should leave the key in place. There's little to gain by removing it. The LO100i is so limited that the presence of the key isn't really an addition. I went through the normal options on my LO100i, and can't find a way to remove the key; only options to replace it. I also checked the support manual. No luck.
