Updating ILO on HP DL380 G7 fails due to firmware version gap

Solution 1:

You typically need to update to ILO3 version 1.28 and then move to version 1.50.

As you can can see below, I keep both ILO versions handy on my jump server, just in case I encounter an ILO3 with a <1.20 firmware version.

In the ILO firmware package README file:

PREREQUISITE: iLO 3 v1.20 BUILD DATE: 8/20/2012 EFFECTIVE DATE: 9/24/2012 DESCRIPTION: Firmware for the Hewlett-Packard Integrated Lights-Out 3 Management Controller

LAST RECOMMENDED OR CRITICAL VERSION: 1.28

PREVIOUS VERSION: 1.28 UPGRADE REQUIREMENTS:

RECOMMENDED: Includes new enhancements, features, and/or minor bug fixes.

FIRMWARE DEPENDENCY: iLO 3 should be upgraded to v1.20 before upgrading to this version.
