NAME

iCAP --Instant Capacity software for HP-UX

DESCRIPTION

The HP Instant Capacity program provides services for instantly increasing or decreasing processing capacity on supported HP servers to meet varying system demands. An Instant Capacity server is an HP cellular (partitionable) server that is governed by an Instant Capacity contract constraining the number of cores, cell boards, and memory that must remain inactive at all times. The total number of each type of component that can be active at any time is referred to as the number of usage rights for that component type. The Instant Capacity software provides the ability to dynamically assign usage rights where they are needed among the various partitions of a complex through the use of commands like icapmodify(1M) and parmodify(1M), and it provides the means to load balance system processing capacity through these management commands. When the processing demand significantly changes, you can purchase additional component usage rights to increase the overall number of components that can be activated at any time.

Instant Capacity is a part of the HP Utility Pricing Solutions (UPS) program, and was formerly known as iCOD. For detailed information about Instant Capacity, see the HP Instant Capacity user’s guide located at /usr/share/doc/icapUserGuide.pdf.

Initializing an Instant Capacity Server

Instant Capacity software is installed by HP manufacturing on instantly ignited systems, and is a required component of all HP-UX systems. You can upgrade to later versions by downloading it from http://www.hp.com/go/softwaredepot (search for product ID B9073BA), or by installing it from an OE or AE update.

An Instant Capacity server needs no additional initialization, but some of the following configuration steps might be useful:

1.Execute the icapmodify -ccommand to configure contact information (email address) for configuration change notification and exception reports.

2.If using temporary capacity, execute the icapmodify -wcommand to configure the temporary capacity warning period.

3.If the server is a GiCAP Group Manager or a member of a GiCAP group, use the cimconfig command (see cimconfig(1M)) to set the CIM Server configuration property sslClientVerificationMode to “optional”. You might need to restart the CIM Server (see cimserver(1M)) if the property was not previously set to this value.

Codewords

Instant Capacity uses codewords for several purposes: to adjust available usage rights for system components, to apply an amount of “temporary capacity” to the system, and to apply “sharing rights” to a Global Instant Capacity (GiCAP) Group Manager to enable creation of one or more groups of member servers that can share usage rights.

All types of codewords must be purchased as specific product numbers from HP. After purchase, the codeword (an encrypted string) must be retrieved from the Utility Pricing Solutions web portal and applied to the appropriate system. Codewords are generated specifically for the system for which they were purchased. You must always specify at least the system serial number and the purchase order number in order to retrieve a codeword from the portal. Application and use of GiCAP codewords are different from other iCAP codewords and are described in the section “GiCAP Sharing Rights”.

Prior to activating an Instant Capacity component, a Right to Use (RTU) codeword must be applied to the complex to increase the component-specific usage rights on the complex. After a
