Glossary

This is memory that can be only added to virtual partitions while the virtual partition is up. This memory cannot be deleted from a virtual partition while it is up.

Using nPartition commands, you can re-configure a portion of a cell’s ILM memory to be used instead as CLM.

A CPU (core) on a specific cell in an nPartition. Using CLP notation to add or delete CPUs from a virtual partition specifies the cell where the CPU resides.

The vPars ability to add or remove memory while a virtual partition is running.

This is memory that can be either added to or deleted from a virtual partition while the virtual partition is up.

The nPartition’s system default is to have all memory configured as ILM.

Using nPartition commands, you can re-configure a portion of a cell’s ILM memory to be used instead as CLM.

A CPU (core) on a specific cell in an nPartition. Using CLP notation to add or delete CPUs from a virtual partition specifies the cell where the CPU resides.

The nPartition’s system default is to have all memory configured as ILM.

A CPU (core) that cannot be migrated from or to virtual partitions while the involved virtual partitions are running. Bound CPUs can handle I/O interrupts.

A CPU (core) that can be migrated from and to virtual partitions while the involved virtual partitions are running. Unbound CPUs cannot handle I/O interrupts. Unbound CPUs are also referred to as floater CPUs.

Virtual Partition Manager. This program provides a GUI to the vPars commands

The actual data-processing engine within a processor. A single processor might have multiple cores. Sometimes referred to as a “processing core”. See also processor.

The vPars ability to add or remove CPUs (cores) while a virtual partition is running.

Any isolated hardware environment, such as a rp7400 server or an nPartition within a Superdome complex.

A mixed HP-UX 11i v2/v3 vPars environment allows you to have a vPars A.05.xx Monitor and database that simultaneously supports virtual partitions running vPars A.05.xx on HP-UX 11i v3 (B.11.31) and virtual partitions running vPars A.04.02 or later on HP-UX 11i v2 (B.11.23). Virtual partitions running vPars A.03.xx on HP-UX 11i v1 (B.11.11) are not supported in a mixed HP-UX 11i v2/v3 vPars environment.

A mixed HP-UX 11i v1/v2/v3 vPars environment allows you to have a vPars A.05.03 Monitor and database that simultaneously supports virtual partitions running vPars A.05.03 on HP-UX 11i v3 (B.11.31), virtual partitions running vPars A.04.02 or later on HP-UX 11i v2 (B.11.23), and virtual partitions running vPars A.03.05 on HP-UX 11i v1 (B.11.11).

A mixed HP-UX 11i v1/v2 vPars environment allows you to have a vPars A.04.05 Monitor and database that simultaneously supports virtual partitions running vPars A.04.05 on HP-UX 11i v2 (B.11.23), and virtual partitions running vPars A.03.05 on HP-UX 11i v1 (B.11.11). Virtual partitions running vPars A.05.xx on HP-UX 11i v3 (B.11.31) are not supported in a mixed HP-UX 11i environment that vPars A.04.05 Monitor is running on.

A logical partition of a complex that divides the complex into groups of cell boards where each group operates independently of other groups. an nPartition can run a single instance of HP-UX or be further divided into virtual partitions.

The hardware component that plugs into a processor socket. Processors can contain more than one core. See also core.

A vPars feature that allows console I/O to be multiplexed to one hardware console port.

Software partition of a hard partition where each virtual partition contains an instance of HP-UX. Though a hard partition can contain multiple virtual partitions, the inverse is not true. A virtual partition cannot span a hard partition boundary

HP software product that allows software partitioning.

The program that manages resources using the virtual partition database, boots virtual partitions and their kernels, and emulates certain firmware calls.

The database that contains the configuration for all the virtual partitions.
