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

• The Instant Capacity software sends an asset report to HP (daily at noon, if configured).
• A partition with Instant Capacity is shut down.
• A partition with Instant Capacity is started.
• A partition with Instant Capacity has a configuration change (that is, a core is activated or
deactivated).
• A codeword is applied.
• Usage rights are seized from a GiCAP system.
You can view all events in the Instant Capacity log files in the /var/adm/icap.log or /var/
adm/icap.log.old file on HP-UX systems, and in the sys$manager:icap.log file on
OpenVMS systems. GiCAP events can be viewed on the Group Manager system in /var/adm/
GiCAP.log (see “Global Instant Capacity” (page 110)).
How can I obtain codewords for newly purchased usage rights if the Utility Pricing Solutions portal
is down?
If the Utility Pricing Solutions portal is down, contact the HP Response Center. The Response Center
can create an emergency codeword via the Instant Capacity codeword backup tool.
What licensing is required for the Instant Capacity software?
For Instant Capacity version 10.x, to activate additional components (cores, cell boards, or memory),
you must acquire additional usage rights individually. For details, see “Usage Rights Requirement”
(page 23)s. To create a Global Instant Capacity group, you must purchase sharing rights. For
more information about sharing rights, see “Global Instant Capacity Sharing Rights” (page 74).
The resulting configuration of my Instant Capacity system does not agree with what I ordered from
HP. How did this configuration change occur?
The Instant Capacity software can control the granularity of processor activation or deactivation
to the single-core level. The Instant Capacity ordering and manufacturing rules often do not allow
such fine granularity.
The Instant Capacity ordering rules dictate the quantity of cores with and without usage rights in
the cell boards. Because the Instant Capacity software distributes the core usage rights (for a given
partition) in a manner that optimizes loads across all cells, the resultant configuration might be
different than the original order. However, the number of cores with and without usage rights
matches what was ordered.
For example, suppose you order an rx8620 server with 2 cell boards, in which the first cell board
contains 4 active cores with usage rights, and the second cell board contains 2 active cores with
usage rights and 2 inactive cores without usage rights, for a total of 6 active and 2 inactive cores.
At run time, the Instant Capacity software balances the distribution of active cores across the cell
boards so that each cell has 3 active cores with usage rights and 1 inactive core without usage
rights.
How does Instant Capacity interact and coexist with partitions running software other than HP-UX?
Instant Capacity is supported only on HP-UX and OpenVMS for Integrity systems. If other partitions
of an Instant Capacity system are running another operating system, all the system components in
the non-HP-UX and OpenVMS partitions appear to the Instant Capacity software as active
components (with usage rights). When verifying the correct number of inactive components without
usage rights, only the HP-UX and OpenVMS partitions are examined.
What email is sent by the Instant Capacity software?
The following table lists the email messages sent to the system from the Instant Capacity software.
On OpenVMS systems, the iCAP software agent is ICAP_SERVER rather than icapd.
