Chapter 7. Using the Capacity Upgrade on Demand Feature
The Capacity Upgrade on Demand feature allows a new system to be ordered with extra processor
capacity that can be enabled by the system administrator. Also, if a system that is already in use requires
additional processor capacity, the system can be upgraded with additional capacity that can be enabled by
the system administrator anytime additional capacity is required. The service representative can also
enable processors during hardware upgrade installation.
Note: The Capacity Upgrade on Demand feature is available for this system when a minimum of four
processors running at 750 MHz processor are installed. The Capacity Upgrade on Demand feature
is not available on systems in which 500 MHz processors are installed.
System Processors
The processors are ordered by feature code (FC) for the system on which you are installing the additional
capacity. The following feature codes can be ordered with the system, or added as upgrades to allow
additional processors to be installed in the system and then enabled later.
FC 8306
This Capacity Upgrade on Demand feature code causes a processor board with four processors to
be installed, but none of the processors are enabled. Only one of these feature codes can be
installed.
FC 8307
This Capacity Upgrade on Demand feature code causes a processor board with four processors to
be installed, and two of the processors are enabled.
After the system is running with any of the above features installed, if the system administrator enables
additional processors on a processor board, the records for the system are changed to show that the
appropriate feature code is in use.
As processors are enabled by the system administrator, the feature records for the system are
automatically updated in the AIX error logs to reflect the number of processors in use. For system records
purposes, the error logs record changes to the processor configuration and the changes are sent, using
the Electronic Service Agent, to the CUoD (Capacity Upgrade on Demand) project office.
