HP-UX Virtual Partitions 6.0 Administrator Guide

the vparconsole command to start, and enter the console in interactive mode right after the

start.

Example 27 Boot the virtual partition called Oslo

vparboot -p Oslo

vparconsole -P Oslo -fic pc -on

NOTE: If you have a boot disk for a vPar, and the vPar is deleted, and another vPar is built using

the same boot disk, when the new vPar boots, the OS will assign a new LAN instance number or

ID to the NIC, even if the new vPar has exactly the same resources as the old one. This will result

in all of the start-up processes involving networking timing out, and an inability to communicate

with any other system until /etc/rc.config.d/netconf is edited.

Modifying a virtual partition

You can modify all the attributes that you specify while creating a vPar. You can rename the vPar,

modify the resources, and change group and user level authorization. Some attributes can be

modified dynamically, that is, a reboot is not required, while others require a reboot.

Just as the vparcreate command, the vparmodify command must be run from the VSP.

The same options used for creating a virtual partition are applicable for modifying the virtual

partition.

Modifying CPU resources – dynamically

In vPars v6.0, you can modify only the CPU cores dynamically. You can change the CPU core

count of a vPar while it is running. You need not reboot the vPar after you modify the CPU core

count.

Modifying memory and I/O resources – statically

To modify the memory size and the I/O devices of a vPar, the vPar must be in the DOWN run

state. After you modify the memory and I/O, reboot the vPar. As an exception, an individual

storage device can be added to the virtual partition, as long as a free target exists on an existing

virtual partition device. If all 8 target addresses on a device are full, and a new device must be

added, the virtual partition must be in the DOWN state to add that device.

NOTE: The I/O refers to legacy AVIO devices.

Modifying vPar name and number

The vPar must be in the DOWN run state to modify the name. You can modify the name of a virtual

partition using vparmodify -P to add a name that does not exist in the current virtual partition

database. The vPar number cannot be modified. The only way you can get a different number is

to destroy the current vPar configuration and recreate it. When it is recreated you can specify the

vPar number with the -p option.
