can be installed either from an HMC or from a running partition in case that system is not
managed by an HMC. For update details, see the Microcode Web page:

If you use an HMC to manage your server, use it also to view the levels of server firmware
and power subsystem firmware that are installed on your server and are available to
download and install.
Each IBM System p server has the following levels of server firmware and power subsystem
firmware:
Installed level: This is the level of server firmware or power subsystem firmware that has
been installed and will be installed into memory after the managed system is powered off
and powered on. It is installed on the
Activated level: This is the level of server firmware or power subsystem firmware that is
active and running in memory.
Accepted level: This is the backup level of server or power subsystem firmware. You can
return to this level of server or power subsystem firmware if you decide to remove the
installed level. It is installed on the
IBM provides the concurrent firmware maintenance (CFM) function on System p systems.
This function supports applying nondisruptive system firmware service packs to the system
concurrently (without requiring a reboot to activate changes). For systems that are not
managed by an HMC, the installation of system firmware is always disruptive.
The concurrent levels of system firmware can, on occasion, contain fixes known as
These deferred fixes can be installed concurrently but are not activated until the next IPL. For
deferred fixes within a service pack, only the fixes in the service pack, which cannot be
concurrently activated, are deferred. Figure 4-8 shows the system firmware file naming
convention.
