Instant Capacity Summary
HP Instant Capacity software provides the ability to instantly increase or decrease computing
capacity on specified HP enterprise servers.
NOTE: HP Instant Capacity for HP 9000 and HP Integrity Servers, also known as Instant
Capacity or iCAP, was known in earlier versions as Instant Capacity on Demand, or iCOD.
Although the commands, warning messages and error messages refer to the software as iCAP,
some internal files might still refer to iCOD.
NOTE: For simplicity and commonality, this book uses the HP-UX commands in all examples.
For information about OpenVMS command equivalents, see Appendix B (page 209).
With Instant Capacity, you initially purchase an HP enterprise server with a specified amount
of active processing capacity, and a specified amount of inactive processing capacity. This amount
can vary based on your sales contract with HP.
Processing capacity consists of the system components:
• Processors containing cores
• Cell boards
• Memory
For each type of component, the number of components that can be active is equal to the number
of usage rights applied to the complex for that type of component. Componentsthat are purchased
with a part number identifying them as “Instant Capacity” and without the label “Right to Use”
come without usage rights. Components that are not labeled “Instant Capacity” implicitlyinclude
usage rights that can be applied to any component of that type that is installed on the complex.
Prior to activation of an inactive component, you must obtain additional usage rights. The
fundamental method is to purchase usage rights by purchasing the appropriate Instant Capacity
products that include the label “Right to Use (RTU)”. HP then supplies an RTU codeword. When
the codeword is applied to the HP enterprise server, the inactive component can be activated.
Additional methods for activating components for which usage rights have not been purchased
include:
• If an HP-UX server is a member of a Global Instant Capacity (GiCAP) group, and if extra
capacity is available from other members of the group, capacity can be “borrowed” from
another member of the group. For information about GiCAP, see Chapter 7.
• Youcan purchaseadditional temporary capacity and apply the Temporary Instant Capacity
(TiCAP) codeword in order to activate one or more cores temporarily. For more information
on TiCAP, see Chapter 5. If a server is a member of a GiCAP group, temporary capacity can
be shared among members of the group.
• You can temporarily activate one or more inactive cores using the Instant Access Capacity
(IAC) provided with the initial purchase of the Instant Capacity component. Instant Access
Capacity is the same as TiCAP except it is automatically provided with an Instant Capacity
component andcannot be purchased separately. It provides an immediate buffer of temporary
capacity in case extra capacity is needed before there is time to purchase an RTU or a TiCAP
codeword, or to set up a GiCAP group on an HP-UX system.
IMPORTANT: It is always a good idea to keep some quantity of temporary capacity in reserve.
Purchase of codewords may take one or more days, so having a buffer of temporary capacity
allows you to avoid delays in activation of additional cores. Instant Access Capacity provides
this buffer initially, but as that capacity is depleted, ongoing purchases of additional temporary
capacity are recommended to replenish it.
The Instant Capacity software product is a part of the HP Utility Pricing Solutions (formerly On
Demand Solutions) program.
18 Introduction to Instant Capacity
This document provides you with the most recent information about using the Instant Capacity
version 9.x software to manage processing capacity in your HP enterprise server.
NOTE: All personnel with system administrator access (that is, root login privileges) to an
Instant Capacity system should read and understand the contents of this document and the
implications of increasing or decreasing processing capacity.
Terminology
For commonly used terms associated with the HP Utility Pricing Solutions program, see the
Glossary.
Instant Capacity Summary 19
Overview
Software Product Overview
The following Instant Capacity software products are associated with HP’s Utility Pricing
Solutions program:
• iCOD: HP product number B9073BA (HP-UX)
• iCAP: HP OpenVMS product number BA484AA
This user's guide contains information for Instant Capacity version 10.x on HP-UX systems and
version 9.x on OpenVMS systems.
Instant Capacity must be run on a partitionable system. In an Integrity Virtual Machines (VM)
environment, Instant Capacity software provides meaningful functionality only on the VM Host
system; it does not run on a virtual machine (also known as a “guest”).
The Instant Capacity product has been available on HP-UX since March 2000 (version B.01.00).
The HP-UX version 9.x software can be obtained from the following HP Software Depot website
(search for “Instant Capacity”):
http://www.hp.com/go/softwaredepot
System Overview
Instant Capacity version 9.x consists of the following elements:
• Instant Capacity system hardware (including cells, cores, and memory)
• Instant Capacity software
• Utility Pricing Solutions Portal
• Instant Capacity Administration System
• Instant Capacity database
• Other system management commands
For more information about Instant Capacity concepts and methods, see Chapter 2: “Getting
Started” (page 27).
Figure 1-1 (page 21) shows how the Instant Capacity system elements and processes are linked.

Instant Capacity System Hardware
Instant Capacity Software
The Instant Capacity system hardware is made up of the following components:
• Cell boards
• Processors, which contain cores
• Memory
Every Instant Capacity system contains a combination of these components that are purchased
either with usage rights (and available for activation) or without usage rights (must be inactive).
Note that although you purchase processors, the Instant Capacity software monitors and manages
cores.
The Instant Capacity software provides the means to:
• Increase or decrease (load balance) system processing capacity (icapmodify command).
• View status and configuration of the system components (icapstatus command).
• Administer system identification and notification information (icapmodify command).
• If configured, send system asset reports through encrypted email to HP (icapd daemon on
HP-UX, ICAP_SERVER process on OpenVMS).
• Send configuration change notification, through encrypted email, to the specified system
contact.
Overview 21
• Monitor and report system compliance (icapd daemon on HP-UX, ICAP_SERVER process
on OpenVMS).
• Manage Global Instant Capacity groups (icapmanage command).
For detailsabout these commands on HP-UX, see “Instant Capacity HP-UX Manpages” (page 149).
For the OpenVMS equivalents of these commands, see “DCL Commands” (page 212).
Utility Pricing Solutions Portal
The Utility Pricing Solutions (or Instant Capacity) portal is located at the HP web site:
http://www.hp.com/go/icap/portal
After you purchase a component without usage rights, HP sends you a letter containing
instructions on how to obtain an RTU codeword from the Utility Pricing Solutions portal.
Instant Capacity Administration System
If asset reporting is configured, the icapd daemon sends asset reports, in the form of encrypted
email messages, to the Instant Capacity Administration System, which saves information in the
Instant Capacity database.
Instant Capacity Database
The Instant Capacity database is a repository on an HP (internal) corporate server that tracks
system resources and provides the information for codeword generation. Note that this database
should not be confused with a Global Instant Capacity database, which is created on a customer
Group Manager system. See Chapter 7 (page 101) for details about Global Instant Capacity.
Other System Management Commands
Other system management commands (such as vparmodify, parCLI and parMgr on HP-UX)
provide an interface to modify system configuration that affects Instant Capacity contractual
compliance.

Instant Capacity Requirements
Program Requirements
To participate in the Instant Capacity version 9.x program, you must comply with the following
conditions of the HP Utility Pricing Solutions program:
• Maintain the HP Instant Capacity software on each HP-UX or OpenVMS partition in the
system. The Instant Capacity software is a nonintrusive, low-overhead software module
that resides on the partition.
• Migrate to later Instant Capacity software versions as they become available.
For specifics about your individual program requirements, see the Utility Pricing Solutions
contract from HP or your authorized channel partner.
IMPORTANT: Participants in the Utility Pricing Solutions program who do not meet these
requirements may be in breach of contract. This can result in unnecessary expense for both the
program participant and HP.
Software Requirements
Every HP-UX and OpenVMS partition in an Instant Capacity system is required to have the
Instant Capacity software installed and the icapd daemon running (on HP-UX systems), or the
ICAP_SERVER process running (onOpenVMS systems).Youmust maintain theInstant Capacity
software until all program requirements are fulfilled and until the system is no longer considered
an Instant Capacity system. If you are using GiCAP, all systems must be running Instant Capacity
version 9.x.
NOTE: For necessaryHP-UX updates, install the latest Operating Environments Update Release
(OEUR) or Application Release (AR) update, if possible. This ensures that you install all required
products and versions. Instant Capacity does not work correctly with HP-UX releases prior to
December 2004.
Your Instant Capacity system is ordered and shipped with all of the following required software
and dependent products, with the exception of the vPars software. If your system’s operating
system is reinstalled or installed with Ignite-UX, ensure that the following software requirements
are satisfied.

Network Requirements
GiCAP and iCAP do not use any network ports directly. However, version 9.0 GiCAP uses
WBEM/SSL for the communication protocol, requiring use of the CIM HTTPS port 5989. GiCAP
also uses ping (which uses port 7 for the echo protocol) and host lookup services (getaddrinfo
and getnameinfo) which may use the Domain Name System (DNS), Network Information
Service (NIS), or a local host file to provide the lookup function.
Email Requirements
For some configurations, previous versions of the Instant Capacity software (prior to B.07.x)
required email connectivity to HP in order to send asset reports as encrypted email messages.
Instant Capacity version B.07.x and later no longer require email connectivity or asset reporting,
however, you can choose to configure it because it can be useful for viewing complexwide asset
information at the Utility Pricing Solutions portal (http://www.hp.com/go/icap/portal).
