HP Instant Capacity User's Guide for Versions 8.x

Instant Capacity Codewords
Instant Capacity uses codewords for several purposes: to adjust available usage rights for system
components (RTU codewords), to apply an amount of 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. See the Utility Pricing
Solutions web portal information in “System Overview” (page 24) for details.
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 103) and are referred to as “GiCAP codewords”. Other
types of codewords are referred to as “iCAP codewords”.
The following iCAP codewords are applied to a server using the icapmodify -C command:
• Core RTU
• Cell board RTU
• Memory RTU
• Temporary capacity
See “Acquiring and Configuring Temporary Instant Capacity” (page 77) for details on the use
of temporary capacity codewords.
Application of an RTU codeword adjusts the number of component-specific usage rights on the
system. As a result, more components can be simultaneously active.
IMPORTANT: iCAP 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.
