The following example uses the convention:
01SV810_030_030 = POWER8 Entry Systems Firmware for 8284-22A
An installation is disruptive if the following statements are true:
򐂰 The release levels (SSS) of currently installed and new firmware differ.
򐂰 The service pack level (FFF) and the last disruptive service pack level (DDD) are equal in
new firmware.
Otherwise, an installation is concurrent if the service pack level (FFF) of the new firmware is
higher than the service pack level currently installed on the system and the conditions for
disruptive installation are not met.
4.4.3 Concurrent firmware update improvements
Since POWER6, firmware service packs are generally concurrently applied and take effect
immediately. Occasionally, a service pack is shipped where most of the features can be
concurrently applied; but because changes to some server functions (for example, changing
initialization values for chip controls) cannot occur during operation, a patch in this area
required a system reboot for activation.
With the Power-On Reset Engine (PORE), the firmware can now dynamically power off
processor components, make changes to the registers and re-initialize while the system is
running, without discernible impact to any applications running on a processor. This
potentially allows concurrent firmware changes in POWER8, which in earlier designs,
required a reboot to take effect.
Activating some new firmware functions requires installation of a firmware release level. This
process is disruptive to server operations and requires a scheduled outage and full server
reboot.
4.4.4 Electronic Services and Electronic Service Agent
IBM transformed its delivery of hardware and software support services to help you achieve
higher system availability. Electronic Services is a web-enabled solution that offers an
exclusive, no-additional-charge enhancement to the service and support that is available for
IBM servers. These services provide the opportunity for greater system availability with faster
problem resolution and preemptive monitoring. The Electronic Services solution consists of
two separate, but complementary, elements:
Electronic Services news page
The Electronic Services news page is a single Internet entry point that replaces the multiple
entry points, which are traditionally used to access IBM Internet services and support. With
the news page, you can gain easier access to IBM resources for assistance in resolving
technical problems.
NN Platform and class SV Low end

FFF Current fix pack
DDD Last disruptive fix pack
