- activated processor
A processor that has been
turned on by the iCOD software or during installation. Processors
are activated with the icod_modify command while HP-UX is running.
- add-on system
A non-iCOD system that has
been converted to an iCOD system. This process is performed by a
HP service representative.
- bound processor
A processor that can process
interrupts for a virtual partition. Bound processors cannot be migrated
from one virtual partition to another if either of the partitions
is running. Every virtual partition must have at least one bound
processor.
- configured processor
A processor that has been
configured at the boot console handler (BCH) and is now available
for activation.
- codeword
The iCOD-component licensing
mechanism used with iCOD versions B.06.x software. Prior to activating
an iCOD component, a right-to-use (RTU) codeword must be applied
to an iCOD system. Codewords are obtained from the iCOD web portal
after an iCOD component has been purchased.
- deactivated processor
A processor that either has not yet been activated or that has been turned off by the iCOD software and returned to the pool of inactive processors. These processors are available for activation.
Note that new HP-UX processes are not assigned to a deactivated processor and all processes running on the deactivated processor are migrated to other processors (with the exception that interrupt handlers may not be migrated from deactivated processors).
- deconfigured processor
A processor that has not
yet been configured at the boot console handler (BCH). The iCOD
software cannot activate a processor that is deconfigured.
- hard partition
A physical partition of a
HP server, comprising a group of cells (containing processors and
memory), and I/O chassis. Each hard partition operates independently
of other hard partitions, and can run a single instance of HP-UX,
or can be further divided into virtual partitions. Hard partitions
are also referred to as “nPartitions”.
- iCOD component
An iCOD component is a system
component (processor, cell, or memory) that has not been licensed
with HP. Before you can use an iCOD component it must be licensed
with HP through the application of a right-to-use (RTU) codeword.
- iCOD processor
A processor that is physically
installed in an iCOD system, but is not licensed, nor activated.
After licensing, iCOD processors can be turned on by the iCOD software
or during installation. Licensed processors are activated with the
icod_modify command while HP-UX is running.
- inactive cell
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”.
- inactive partition
A partition where all of
the cells in the partition are inactive.
- inactive processor
A processor in an iCOD system
that is currently inactive. Licensed inactive processors are capable
of activation by use of the icod_modify command. An inactive processor is also referred to as
a “deactivated processor”.
- migrating processors
The process of activating
and deactivating processors across partitions for load-balancing.
See “Load-Balancing
Active Processors” for more
information.
- monarch processor
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.
- online activation
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.
- pay per use
The HP software product,
which is a part of the HP Utility Pricing Solutions program, that
has a pricing model in which you are charged for the processor percent
utilization. You acquire a specific hardware platform, and number
of processors, and are charged for the percent utilization of the
processors depending on system demand.
- right to access
The initial fee a customer
pays to enter the iCOD program and physically acquire possession
of an iCOD (inactive) processor.
- temporary capacity
A 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 also referred
to as “TiCOD”.
- unbound processor
A processor that can be migrated
between virtual partitions while the involved partitions are running. Unbound
processors cannot handle I/O interrupts. Unbound processors may
also be referred to as “floater processors”.
- virtual partition
A software partition of a
computer, or of a single hard partition, where each virtual partition
can run its own instance of HP-UX. A virtual partition cannot span
a hard partition boundary.
- vPars
A HP Software product that
allows software partitioning.
