Chapter 4. Continuous availability and manageability 133
Draft Document for Review May 12, 2014 12:46 pm 5102ch04.fm
򐂰 A scheduled maintenance action will cause a platform reboot, which provides an
opportunity to also upgrade to a new firmware release.
The updating and upgrading of system firmware depends on several factors, such as whether
the system is stand-alone or managed by a management console, the current firmware
installed, and what operating systems are running on the system. These scenarios and the
associated installation instructions are comprehensively outlined in the firmware section of
Fix Central:

Firmware update steps
The system firmware consists of service processor microcode, Open Firmware microcode,
SPCN microcode.
The firmware and microcode can be downloaded and installed either from an HMC, from a
running partition, or from USB port number 1 on the rear, if that system is not managed by an
HMC.
Power Systems has a permanent firmware boot side (A side) and a temporary firmware boot
side (B side). New levels of firmware must be installed first on the temporary side to test the
update’s compatibility with existing applications. When the new level of firmware is approved,
it can be copied to the permanent side.
For access to the initial web pages that address this capability, see the Support for IBM
Systems web page:

For Power Systems, select the Power link.
Although the content under the Popular links section can change, click the Firmware and
HMC updates link to go to the resources for keeping your system’s firmware current.
If there is an HMC to manage the server, the HMC interface can be use to view the levels of
server firmware and power subsystem firmware that are installed and that are available to
download and install.
