As previously mentioned, 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 may have fewer active components than they have
rights to activate. Such systems may 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 RTU Purchase | |
When the processing demand significantly changes,
you can enable use of additional system components using the following
procedure: Purchase
additional usage rights for a component type — this is accomplished
by sending a purchase order (P/O) to HP for an RTU product. Soon after
your P/O is received by HP, you should receive a letter from HP that
contains information about retrieving the RTU codeword from the Utility
Pricing Solutions web portal. Acquire
the RTU codeword from the Utility Pricing Solutions web portal, http://www.hp.com/go/icap/portal Apply
the RTU codeword — by using the icapmodify -C command/option (note the -C option is uppercase)
on any partition in the complex. Activate
a component — depending on the type of component, this is accomplished
as follows: Activate
a core in a hard partition (npar) by use of the icapmodify -a command. Note: For details about activating a core in a virtual
partition, see “Instant Capacity Integration with Virtual Partitions (HP-UX
only)”. Activate
a cell board by using the parmodify or parmgr command. See “Activation of an Instant Capacity Cell Board” for details on activation of cell
boards (and memory).
| | | |  | IMPORTANT: To avoid a delay in activation of additional cores,
it is a good idea to purchase and keep in reserve some quantity of
Temporary Instant Capacity for the system. Temporary Instant Capacity
can be used to instantly and temporarily activate cores while waiting
for an RTU codeword to be acquired, as in Step 1. See Chapter 5 for details about Temporary
Instant Capacity. You may also temporarily activate one or more cores
using the Instant Access Capacity (IAC) provided with the purchase
of Instant Capacity processors. | | | | |
