IBM Power System E850C: Technical Overview and Introduction
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 websites that address this capability, see the POWER8 section on the
IBM Support Portal:
https://www.ibm.com/support/entry/portal/product/power
For POWER8 based Power Systems, select the POWER8 systems link. Within this section,
search for Firmware and HMC updates to find the resources for keeping your system’s
firmware current.
If you use an HMC to manage the server, that interface can be used to view the levels of
server firmware and power subsystem firmware that are installed, and those that are available
to download and install.
Each IBM Power Systems server has the following levels of server firmware and power
subsystem firmware:
Installed level
This level of server firmware or power subsystem firmware is installed, and will be installed
into memory after the managed system is powered off and then powered on. It is installed
on the temporary side of system firmware.
Activated level
This level of server firmware or power subsystem firmware is active and running in
memory.
Accepted level
This level 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 permanent side of system firmware.
Figure 4-4 shows the different levels as shown in the HMC.

IBM provides the CFM function on the Power E850C model. This function supports applying
nondisruptive system firmware service packs to the system concurrently (without requiring a
reboot operation to activate changes).
The concurrent levels of system firmware can, on occasion, contain fixes that are known as
deferred
. These deferred fixes can be installed concurrently but are not activated until the
next IPL. Deferred fixes, if any, are identified in the Firmware Update Descriptions table of the
firmware document. For deferred fixes within a service pack, only the fixes in the service pack
that cannot be concurrently activated are deferred.
