I tripped over the following blog post that describes a simple way to reset the iLO Administrator Password without having to reboot the server:

To summarize, follow the steps below to reset the password for the iLO-account named Administrator:
- Install “HP Lights-Out Online Configuration Utility” if it is not already installed in the server.
- Create an XML-file with the following contents:
<ribcl VERSION=“2.0”><login USER_LOGIN=“Administrator” PASSWORD=“boguspassword”><user_INFO MODE=“write”><mod_USER USER_LOGIN=“Administrator”><password value=“newpass”/></mod_USER></user_INFO></login></ribcl>
- Execute the following command in a command prompt on the server:
HPONCFG.exe /f xml-file-above.xml /l log.txt > output.txt
