Glossary
bound CPU a CPU that cannot be migrated from or to virtual partitions while the involved
virtual partitions are running. Bound CPUs can handle IO interrupts.
dynamic CPU migration the vPars ability to add or remove floater CPUs while a virtual
partition is running.
hard partition any isolated hardware environment, such as a rp7400 server or an nPartition
within a Superdome complex.
nPartition 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.
unbound CPU a CPU that can be migrated from and to virtual partitions while the involved
virtual partitions are running. Unbound CPUs cannot handle IO interrupts. Unbound CPUs
are also referred to as floater CPUs.
virtual consoles a vPars feature that allows console IO to be multiplexed to one hardware
console port.
virtual partition 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
vparmgr Virtual Partition Manager. This program provides a GUI to the vPars commands
vPars HP software product that allows software partitioning.
vPars Monitor the program that manages resources using the virtual partition database,
boots virtual partitions and their kernels, and emulates certain firmware calls.
vPars partition database the database that contains the configuration for all the virtual
partitions.
