HP Instant Capacity Version 10.x User Guide (5900-1581, March 2011)

If you do not want an email notification to be sent when configuration changes are made, disable
this feature by using the following command on HP-UX systems:
/usr/sbin/icapnotify -n off
Example 1 shows a configuration change email notification the Instant Capacity software sends
to the system contact. Note that if the operation is a deferred configuration change, “previous”
and “current” show equal values; only the value for “Number of cores to be active after reboot”
reflects the requested change.

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:

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