5.1 Managing service updates

This section provides an overview on updating the firmware and software for the various
components within the IBM Power 775 High Performance Computing cluster.

5.1.1 Service packs

Service packs are used to indicate components and levels of components that are verified to
operate together. The service pack includes a readme file for installing and updating the IBM
HPC clustering with Power 775. The service pack also contains the following useful service
information:
Software offerings
Recommended code levels
Recommended installation sequence
Known restrictions and limitations
Known problems and workarounds
Hints and tips
Service pack support matrix and archive
For the latest information about applying code maintenance, see the appropriate service pack
on the IBM HPC clustering with Power 775 servers/service packs portion of the IBM High
Performance Computing clusters service packs at this website:

If your service pack is not listed, see the most recent service pack and access the archived
service packs that lists your service pack.

5.1.2 System firmware

This section describes the basic steps for updating and validating firmware updates to the
frame power code and the CECs GFW system firmware.
For more information about updating the Central Electronic Complex (CEC) firmware, and

IBM fix central
Locate and download the supported Power 775 power code and GFW System firmware
(CEC) from IBM fix central to a directory on the EMS. The IBM HPC clustering with Power
775 service pack contains the recommended code levels. Links to fix central and to download
the firmware are available at this website:
