HP Instant Capacity User's Guide for Version 9.x

2.4 Instant Capacity Codewords
Instant Capacity uses codewords for several purposes: to adjust available usage rights for system
components (RTU codewords), to apply temporary capacity to the system, and to apply sharing
rights to a GiCAP Group Manager system to enable the creation of one or more groups.
All types of codewords must be purchased as specific product numbers from HP. After purchase,
the actual codeword (an encrypted string) can be retrieved from the Utility Pricing Solutions
web portal. When you retrieve codewords from the portal, you must provide the sales order
number for the codeword purchase and the serial number of the system. For more information
about purchasing codewords, see the Utility Pricing Solutions web portal information in “System
Overview” (page 20).
Once obtained from the portal, the rules and uses of GiCAP codewords are very different from
other types of Instant Capacity codewords. The GiCAP codewords are described in “Global
Instant Capacity Sharing Rights” (page 106) and are referred to as “GiCAP codewords”. Other
types of codewords are referred to as “Instant Capacity codewords”.
The following Instant Capacity codewords are applied to a server using the icapmodify -C
command:
• Core RTU
• Cell board RTU
• Memory RTU
• Temporary capacity
For details about using temporary capacity codewords, see “Acquiring and Configuring
Temporary Instant Capacity” (page 77).
Application of an RTU codeword adjusts the number of component-specific usage rights on the
system. As a result, more components can be active simultaneously.
IMPORTANT: Instant Capacity codewords are based on both the serial number of a system and
a unique sequencing value for that server. These codewords must be applied in the sequence in
which they are obtained for a particular server. They can be applied to any partition on the server.
