Configuring vPar Resources and Attributes
When creating or reconfiguring a Virtual Partition, you manage
resources and attributes that determine the vPar’s configuration and
capabilities.
Each Virtual Partition has three types of resources: cpu, io, and mem,
which specify processor(s), I/O, and memory allocated exclusively for the
vPar.
The vPar resource configuration determines which hardware is dedicated
for the vPar’s use, by indicating hardware paths, quantities, and limits.
Each vPar also has three types of attributes: general attributes,
hardware attributes, and boot attributes.
NOTE To modify most vPar hardware resources or attributes, you must ensure
that the vPar being modified is in a “Down” state.
Also note that some vPar attributes are required and some are optional.
See the vparmodify (1M) and vparresources (5) manpages for details.
The following list includes details and command-line options for setting
vPar attributes. Also see the vparcreate (1M) and vparmodify (1M)
command manpages.
• vPar General Attributes
The general vPar attributes include the name of the vPar and the
static attribute.
The name attribute (-p and -P) defines the vPar’s name, which you
use when referencing or managing the vPar using commands.
The static attribute (-S) defines whether the vPar can be
reconfigured. See Dynamic vPars and Static vPars on page 461 for
details.
• vPar Hardware Resource Attributes
vPar hardware resource attributes include specifications for the
processors, I/O, and memory that are dedicated for use by the vPar.
