Core Activation

As previously described, an Instant Capacity system contains a specified quantity of activated processing capacity (cells, cores, and memory) and a specified amount of deactivated processing capacity. Systems can have fewer active components than they have rights to activate. Such systems can instantly activate additional components without the need to purchase an RTU, up to the number of component usage rights on the system.

Increasing Processing Capacity by Purchasing RTUs

When processing demands change significantly, you can enable use of additional system components using the following procedure:

1.Purchase additional usage rights for a component type, by sending a purchase order to HP for an Instant Capacity RTU product. Soon after HP receives your purchase order, you receive a letter from HP that contains information about retrieving the RTU codeword from the Utility Pricing Solutions web portal.

2.Acquire the RTU codeword from the Utility Pricing Solutions web portal: http://www.hp.com/go/icap/portal

3.Apply the RTU codeword by entering the icapmodify -Ccommand (note the -Coption is uppercase) on any partition in the complex.

4.Activate a component. Depending on the type of component, do one of the following:

Activate a core in a hard partition (nPartition) by entering the icapmodify -acommand. Note: For details about activating a core in a virtual partition, see “Instant Capacity Integration with Virtual Partitions (HP-UX)” (page 31).

Activate a cell board by using the parmodify or parmgr command. For details about activation of cell boards (and memory), see “Activation of an Instant Capacity Cell Board” (page 97).

IMPORTANT: To avoid a delay in activation of additional cores, purchase and keep in reserve some quantity of temporary capacity for the system. Temporary capacity can be used to instantly and temporarily activate cores while waiting for an RTU codeword. For details about temporary capacity, see Chapter 5. You can also temporarily activate one or more cores using the Instant Access Capacity (IAC) provided with the purchase of Instant Capacity processors.
