Change Licensed Internal Code for the current release

Use this task to apply updates to the currently installed Licensed Internal Code (also known as system firmware) on your system within the current release. Licensed Internal Code updates can be downloaded directly from IBM's service website. The HMC must be able to connect to a network that is outside of a firewall. If you cannot access IBM's service website from the HMC, go to Fix Central to determine what code level is needed. Download the code to another device, and then copy it to removeable media or to a File Transfer Protocol (FTP) location.

Important: The HMC might need to be updated prior to updating the Licensed Internal Code within the current release. Check the minimum HMC code level section at the Firmware and HMC: Firmware Description Files website (http://www.ibm.com/support/fixcentral/firmware/fixDescriptionFiles).

If the link to the code from the Fix Central website is not working, contact IBM Service to get the correct RPM and XML files.

For more information about Licensed Internal Code updates, see the following information:

• Licensed Internal Code: Frequently asked questions
• System Firmware (Microcode) Service Strategies and Best Practices guide

If you have completed a code update from a repository to one of your managed systems or power subsystems, that code is available in the hard drive repository on the HMC for installation on other systems. You can select Hard Drive to update other managed systems or power subsystems with the same code.

Multiple managed systems can be updated simultaneously by selecting them from the target list.

Files are selectively downloaded to the HMC to apply Licensed Internal Code updates. From this task, you can do the following actions:

• View current levels of Licensed Internal Code on a managed system, power subsystem, or I/O.

• View retrievable levels of Licensed Internal Code in a repository.

• Install and activate Licensed Internal Code updates (update to a new level of the Licensed Internal Code).
• Remove and activate Licensed Internal Code updates (downgrade to a previous level of the Licensed Internal Code).

Select Start Change Licensed Internal Code wizard to perform a guided update of managed system, power, and I/O Licensed Internal Code, complete the following steps:

1. A System readiness check is automatically performed to check that the system is in the right state for the Licensed Internal Code update. If the readiness check fails, actions needed to correct the problems that prevent the update are reported to you.
2. Choose a repository from which to update your system. You can update the system from any of the following repositories:

• IBM's service website.

• Removable media. Ensure that the DVD or CD is in the HMC DVD drive or that the USB flash drive is attached to the HMC.

• FTP site.

• HMC hard disk drive.

If you choose FTP site, you are prompted for the FTP host name, user ID, password, and the directory in which the update is located.

3. Select the type of update to install, which is Managed system and Power LIC. If there are no Licensed Internal Code updates available in the repository for the type of update that is chosen, no prompts for installation occur.

4. Confirm that the update as displayed is the correct update. Displayed is the chosen repository, the target, or targets of the update, the concurrency status of the target (disruptive or concurrent), and the type of installation. To change the update, select Advanced Options.
5. If no changes are wanted, continue with the update. Accept the license agreement.
6. Confirm the update.
7. A progress window displays until the update completes.

Select View system information to examine current Licensed Internal Code levels on a managed system, power subsystem, or I/O, including levels retrievable from a repository.

Select Advanced features to update managed system and power the Licensed Internal Code with more options and more targeting choices.
