Virtual Partitions (vPars) Management on nPartitions
Configuring vPar Resources and Attributes
HP System Partitions Guide: Administration for nPartitions, rev 5.1 448
You can add (-a), delete (-d), and modify (-m) vPar hardware
resources and attributes.
Also see the vparresources (5) manpage for details.
Descriptions of processor (cpu), I/O (io), and memory (mem) vPar
hardware resource attributes are in the following list.
— Processors (cpu) resources — You can specify the following
attributes for processors:
The path of one or more processors that are bound to the
vPar. For example, to set the processor at hardware path 0/10
to be bound to the vPar:
# vparmodify -p name -m cpu:0/10
A minimum and maximum number of processors allowed in the
vPar. For example, to set the minimum number of processors
to 2 and the maximum to 4 processors:
# vparmodify -p name -m cpu:::2:4
The total number of processors in the vPar. For example, to
set the total number of processors to 6:
# vparmodify -p name -m cpu::6
— Input/Output (io) — You can optionally specify boot, altboot,
and other attributes for each I/O device path assigned to a vPar.
The boot attribute specifies the primary (PRI) boot device path
for the vPar, which is stored in the vPars database (vpdb) and is
separate from the nPartition boot device path settings.
The altboot attribute specifies the alternate (ALT) boot device
path for the vPar, which also is separate from nPartition boot
settings.
For example, to set the specified vPar’s PRI boot device path to
0/0/6/0/0.5 (the corresponding nPartition’s PRI path is not
changed, however):
# vparmodify -p name -m io:0/0/6/0/0.5:boot
— Memory (mem) — You can specify the total (-m mem:: size )
memory size in MBytes for a vPar, and can increase (-a) or
decrease (-d) the amount of memory,
As needed, the specified size is rounded up to a 64 MByte
boundary.
