HP-UX vPars and Integrity VM V6.1.5 Administrator Guide (5900-2295, April 2013)

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

start.

Example 10 Boot the virtual partition called Oslo

vparboot -p Oslo

vparconsole -P Oslo -fic 'pc -on'

6.3 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 V6.1.5, 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 128 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.

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.

Example 11 Modify a virtual partition with vHBA

Add a virtualized hba, using NPIV ports (manually assigning port and node WWNs)

# vparmodify -p Oslo \

-a hba:avio_stor:,,0x100000110a030000,0x100000110a030001:npiv:/dev/fcd0

NOTE: If you want to create a vPar that has access to the same storage as a different vPar or

the VSP, or re-create a vPar configuration, giving it the same storage access, you can manually

assign the port and node worldwide names, as in the example.

6.4 Viewing information specific to a virtual partition

You can view information about a vPar by specifying either the name or the number of the vPar.

You must use the vparstatus command from the VSP to view vPar information.
