You have downloaded the Service Pack for ProLiant (spp) in iso format and want to install it using ILO.
In ILO open “Remote Console & Media” and load the iso. Restart the server and start installing the service pack. At some point the installation crashes (at a certain percentage of completion).
The problem is that you used ILO’s HTML5 client to load the ISO; you have to use the Java client.
Hmtl5 remote console unmaps the image after a while
