Hi,   I did spoke to the OME experts on this, and your thought were the same as mine. Apparently the firmware contents are uploaded into LCC for the updates. So therefore, once the server reboots, LCC does the updates and it's just a long reboot, like you mentioned. 
Howdy, When doing the Firmware/Bios updates, there's a box that says: Stage for next server reboot. Can anyone tell me exactly what that box does? Does it do the install right away but just postpones the reboot until later? Or does it just copy the files but doesn't actually do the install until the reboot? With OMEssentials we could set the install to go now but just Not Check the box that said Allow Reboots. That way all the time to do the install would be done now and just the reboot steps would go later. What exactly will happen at the next reboot if I use the Stage option in OMEnt? Thanks,
What does Stage for next reboot mean?
