Hello again,
I don't know if HP SUM can logon to the ILOs, you could give that a try. Are your servers blades or DLs?
The online updates of ILOs need an OS to work so i don't think a better option that the tool i mentioned in the first reply is available. And sad to say i know of the bug, depending on the ILO version you can try older verdions of this tool.
