Have you tried to use a Look at Lan or successor of LaL - Fing, or Angry IP Scanner  for that?

Use something like LanSpy (Freeware) and scan the IP range for HTTPS responses.
Unless you have huge numbers of websites, you should be able to filter out which reponses are not from server NICs. You can compare this to your server inventory.

If you have access to the networking equipment you can check the arp table on the router for the vendor code i belive dedicated ILO is 00:26:55 this won't work with some of the low end HP server with shared iLO/network ports because the iLO will have the 00:50:56 from the network card. Depending on why you are trying to find the servers with iLO this will allow you to find the physical server because it will show you where they are plugged in as-well, by refrencing the mac address table

Before you run your port scanner I suggest you read this, shouldn't harm as you're only scanning for a few ports though.

Here's a good one, not many things except iLOs are going to respond to Virtual Media on port 17988 so scan for that instead of those common ports that just about everything responds to; http://blog.nachotech.com/?p=63

I learnt something on one of the other nachotech blog articles when finding that one, I've not tried "ILO update all..." from OA CLI, going to run it tomorrow just for fun on the blade enclosures I've got under test.

doh (>_<)" according to this article
http://bizsupport1.austin.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=1146658&prodTypeId=15351&objectID=c02629048&printver=true

Open in new window

the server needs to be restarted if I use port scanner :-|
this is very harmful way to discovering hundreds of servers in my datacenter.

You're OK with port scanner if you're just scanning for an individual port -

"This occurs when the port scanner tool opens several new TCP connections faster than the iLO 2 network services can process"

You're only going to open one TCP connection.

That script from nachotech (or the windows equivalent in one of the comments) is better though as it gets the version as well.

OA is onboard administrator, only applies to blades.
