Re: How to recover/retrieve lost ILO Advanced License Key? Your best best would be to contact the HPE Licensing group and see if they could help. Unless you have an Entitlement Order Number (EON) or an HPE Sales Order number, it may be challenging but still worth a shot.
HP iLO Advanced License Activation Keys. Integrated Lights-Out, or iLO, is a proprietary embedded server management technology by Hewlett-Packard which provides out-of-band management facilities. The physical connection is an Ethernet port that can be found on most Proliant servers and microservers of the 300 and above series. FeaturesiLO makes it possible to perform activities on an HP server from a remote location. The iLO card has a separate network connection (and its own IP address) to which one can connect via HTTPS.
