Processor Activation
As previously mentioned, an Instant Capacity system contains a
specified quantity of activated processing capacity (cells, processors, and
memory) and a specified amount of deactivated processing capacity. Not
all components that may be activated need be active. Components that
are allowed by license counts may be deactivated for various reasons,
and can be instantly activated at need.
Increasing
Processing
Capacity
When the processing demand significantly changes, you can enable use
of additional system components using the following procedure:
Step 1. Decrease unlicensed component count — this is accomplished by sending
a purchase order (P/O) to HP for a RTU license codeword. 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.
Step 2. Acquire the RTU codeword from the Utility Pricing Solutions web portal,
http://www.hp.com/go/icod/portal
Step 3. Apply the RTU codeword — by using the icod_modify -C
command/option (note the -C option is uppercase) on any partition in the
complex
Step 4. Activate a component — depending on the type of component, this is
accomplished as follows:
a. Activate a processor in a hard partition (npar) by use of the
icod_modify -a command. Note: For details about activating a
processor in a virtual partition, see “Instant Capacity Integration
with Virtual Partitions” on page 132.
b. Activate a cell board by using the parmodify or parmgr command.
See “Activation of an Instant Capacity Cell Board” on page 100 for
details on activation of cell boards (and memory).
