iCOD Terminology

Processors that have been turned on by the iCOD software or during installation. Processors are activated with the icod_modify command while HP-UX is running.

A non-iCOD system that has been converted to an iCOD system. This process is performed by a HP service representative.

Bound processors have I/O interrupts assigned to them. Because HP-UX cannot migrate I/O interrupts to or from a processor, you cannot dynamically add or remove bound processors to or from a vPar.

Processors that have been configured at the boot interface and are now available for activation.

Processors that have not yet been configured at the boot console interface (BCH). The iCOD software cannot activate a processor that is deconfigured.

The fee a customer pays to activate and use an iCOD processor. This fee pertains to only the iCOD program.

A physical partitioning of a computer that divides the computer into groups of cell boards where each group operates independently of the other groups. A hard partition can run a single instance of HP-UX or be further divided into virtual partitions. Hard partitions are also referred to as “nPartitions”.

Processors that are physically installed in an iCOD system, but are not activated. iCOD processors can be turned on by the iCOD software or during installation. iCOD processors are activated with the icod_modify command while HP-UX is running.

The HP product name of the iCOD software. The HP product number for icod-purchase is B9073AA.

The HP product name of the pay per use (PPU) software. The HP product number for icod-utility is T1322AA.

On a hardware-partitionable system, a cell that is either powered off, or in a state prior to BCH, defined as “waiting on SINC_BIB”.

A partition where all of the cells in the partition are inactive.

A processor in an iCOD system that is currently inactive, but is capable of activation by use of the icod_modify command. An inactive processor is also referred to as a “deactivated processor”.

The process of activating and deactivating processors across partitions for load-balancing. See “Load-balancing Active Processors” for more information.

This is the main controlling processor from the perspective of the operating system. This processor is designated as CPU 0. The LPMC monitor does not deactivate/replace a failing monarch processor.

The ability to activate a deactivated processor while HP-UX is running. No reboot is required. This is done by using the icod_modify command. This is the default behavior of iCOD.

To manually configure a processor for activation from the boot interface, boot to the system prompt, and then use the icod_modify command to activate the processor as you would in the online activation mode (a two step process). A reboot is required for offline configuration.

The HP On Demand Solutions program that is a pricing model in which you are charged for actual processor usage. You acquire a specific hardware platform, and number of processors, and are charged for the actual usage, based on the number of active processors in the complex.

The initial fee a customer pays to enter the iCOD program and physically acquire possession of an iCOD (inactive) processor.

An HP product that enables customers to purchase prepaid processor activation rights, for a specified (temporary) period of time. Temporary capacity is sold in 30 processor-day increments. Temporary capacity is available on HP-UX 11i v1 only.

Unbound processors do not have I/O interrupts assigned to them and can dynamically migrate from one vPar to another.

A software partitioning of a computer or hard partition where each virtual partition contains an instance of an operating system. Though a hard partition can contain multiple virtual partitions, the inverse is not true (that is, a virtual partition cannot span hard partition boundaries). Virtual partitions are also referred to as “vPars”.
