Update HP iLO Firmware on HP Proliant

To update the HP iLO, go to this page http://h18013.www1.hp.com/products/servers/management/iloadv3/index.html and under the section Products Firmware and Tools, click on the version that your server has and download the firmware.

Download the file according to your Operating System. My OS is a Red Hat Enterprise Linux 5, so I downloaded the file and then copied to the server.

iLO 1 v.1.96 – CP023365.scexe
iLO 2 v.2.29 – CP027871.scexe
iLO 3 v.1.20 – CP014002.scexe
You first need to have at least iLO 3 version 1.20 to update to later versions
iLO 3 v.1.85 – CP026424.scexe
iLO 4 v.2.30 – CP026236.scexe

To update, you run the file as shown below

root@linux:/tmp # bash ./CP018561.scexe
