Can i move CPU unbound between VPAR dinamically?

[gigiz]

Hi !!!
I have wlm on two VPAR.I read about wlm that it can move unbound processor between VPAR.
I want know if what it use ... if wlm use prm or pset for do it ...
And if move the CPU by the prm or psets ... What is a manual command for do it ?
Thanks

hi,

manually you can do it with the command vparmodify.
see the man pages for more details. or this document.

I want know how WLM move the unbound CPU, what wlm use ....
PRM or PSET or VPARMODIFY
How can manually emulate the allocation of the unbound cpu ...?
I read on WLM user guide that i can't use vparmodify when wlmpard are running ....
help me ....
Thanks a lot

The manual command to move unbound cpu's from one vPar to another is to run the following on ANY vpar in the server/nPar:

vparmodify -p vparname -m cpu::X

where X is the vPar's new CPU count. So if say vpar1 has 6 cpus and vpar2 has 2 cpus and you want to have vpar2 to have 2 more cpus you do:

reduce vpar1 to 4 cpus freeing up 2 cpus:
# vparmodify -p vpar1 -m cpu::4
verify that there are now free cpus
# vparstatus -A
increase vpar2's cpu count to 4 cpus
# vparmodify 0p vpar2 -m cpu::4

Internally, WLM uses the vparmodify command to move unbound processors from one vpar to another. Another bit of information, you should not have PSETs workload groups in your configuration if you will be doing vpar management in WLM.

Hi

Unbound CPUs that can be dynamically reassigned among partitions,provides greater flexibility of movement between virtual partitions
Can be added and removed without needing to bring down the affected partitions.

(There is document on the HP site somewhere about this)

Hope this helps
