Modifying vPar Configuration Attributes
This section describes how to add or remove resources from a vPar, and
how to change a vPar’s attribute settings.
Many vPar hardware resource changes require that the vPar being
modified is not running (not in an “Up” state).
vPar Management: Modifying vPar Attributes
in nPartition Environments
This procedure describes how to modify a Virtual Partition’s attributes
and resource configuration.
Step 1. Login to HP-UX running on one of the vPars in an nPartition, or login to
HP-UX running in non-vPars mode on an nPartition.
You can modify vPar attributes from HP-UX running in a vPar.
You also can modify vPars database configurations when you have booted
HP-UX in non-vPars mode. By default the vparcreate, vparmodify, and
vparstatus commands use the /stand/vpdb file.
To modify a vPars database other than the /stand/vpdb file, use the -D
option to specify its location.
Step 2. Issue the vparstatus command to list the current status of the vPar you
plan to update.
For detailed info on a vPar use the vparstatus -v -p... command.
