vPars A.05.xx-specific Terms
base memory 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.
CLM (Cell Local Memory) Using nPartition
commands, you can re-configure a portion of a cell’s
ILM memory to be used instead as CLM.
CLP (Cell Local Processor) 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.
dynamic memory migration The vPars ability to
add or remove memory while a virtual partition is
running.
float memory This is memory that can be either
added to or deleted from a virtual partition while the
virtual partition is up.
ILM (Interleaved Memory) The nPartition’s
system default is to have all memory configured as
ILM.
mixed environment 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 (11.31) and virtual partitions running
vPars A.04.02 or later on HP-UX 11i v2 (11.23).
Virtual partitions running vPars A.03.xx on HP-UX
11iv1 (11.11) are not supported in a mixed HP-UX
11i v2/v3 vPars environment.
vPars A.04.xx-specific Terms
CLM (Cell Local Memory) Using nPartition
commands, you can re-configure a portion of a cell’s
ILM memory to be used instead as CLM.
CLP (Cell Local Processor) 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.
ILM (Interleaved Memory) The nPartition’s
system default is to have all memory configured as
ILM.
vPars A.03.xx-specific Terms
bound CPU 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.
unbound CPU 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.
vparmgr Virtual Partition Manager. This program
provides a GUI to the vPars commands
All vPars Versions
core 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.
dynamic CPU migration The vPars ability to add
or remove CPUs (cores) 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.
processor The hardware component that plugs into
a processor socket. Processors can contain more than
one core. See also core.
virtual consoles A vPars feature that allows
console I/O 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
