Vpar Commands +HPUX

Vpar Commands:

vparcreate

vparcreate is used to create a new virtual partition.

# vparcreate -p vpar1

-a cpu::3 -a cpu:::2:4 -a cpu:41 -a cpu:45 (Can be done a LIVE system)

–a mem::1280 (Cannot be done on a LIVE system)

–a io:0/8 -a io:1/10 -a io:0/8/0/0.5.0:boot

vparboot

The vparboot command is used to boot a second vPar from a running vPar.

Boot vpar2 partition from running vpar1 partition:

# vparboot -p vpar2

Boot vpar2 partition to single user mode from running vpar1 partition:

# vparboot -p vpar2 –o “-is”

vparmodify

With vparmodify we can change the resources and attributes of an existing vPar.

Modify the primary boot path to vpar1:

# vparmodify -p vpar1 -m io:0/8/0/0.5.0:BOOT

Set the alternate boot path:

# vparmodify -p vpar1 -a io:0/8/0/0.2.0:ALTBOOT

vparremove

The vparremove command deletes a virtual partition previously created using the vparcreate

command. All resources associated with the virtual partition are made available for allocation

to other partitions.

# vparremove -p vpar1

Remove virtual partition vpar1? [n]: y

vparstatus

Display information about one or more virtual partitions on a system. If Monitor is not loaded

the vparstatus shows this with an message. The output shows also the state of a vPar.

# vparstatus

You can change only Unbound CPUs, for bound CPUs we have to recreate vpar.

# vparstatus -v -test0
