Instant Capacity Codewords

  Table of Contents

  Index

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” 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” and are referred to as “GiCAP codewords”. Other types of codewords are referred to as “iCAP codewords”.

The following 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” 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.
