Step-by-step guide to IBM Power Systems firmware update

26 Mar 2013 04:00:00 +0000

IBM® Power Systems™ firmware update, which is often referred to as Change Licensed Internal Code (LIC) procedure, is usually performed on the managed systems from the Hardware Management Console (HMC). Firmware update includes the latest fixes and new features. We can use the Change Licensed Internal Code wizard from the HMC graphical user interface (GUI) to apply updates to the Licensed Internal Code (LIC) on the selected managed system. We can select multiple managed systems to be updated simultaneously. The wizard also allows us to view the current system information or perform advanced operations. This tutorial provides the step-by-step procedure for the IBM Power Systems firmware update from the HMC command line, and the HMC GUI and is targeted for system administrators. This step-by-step instructions can prepare the newbie for what needs to be done and how it could be done to stay on to the latest firmware level all the time. When you purchase a new hardware, the best practise is to upgrade all the firmware to the latest level.
