I have an rx8620 complex with 2nPars and each nPar has 3 vPars each. The complex has 16 CPU cores in total.
Here the configuration of the CPU's -
==============================
nPar0 CPU's | nPar1 CPU's
==============================
vPar1 - 2 | vPar4 - 2
vPar2 - 2 | vPar5 - 2
vPar3 - 2 | vPar6 - 2
Inactive Core - 2 | Inactive Core - 2
===============================
The inactive cores are activated on-demand by using the TiCAP license.
The requirement here is i have to increase 1 CPUs for all the vPars in nPar0 and there are only 2 inactive cores available on nPar0.
Is it possible to move a CPU from nPar1 (2 inactive cores available) to nPar0 without using GiCAP?
Please advise.
Thanks,
Jayaprakash S

Re: Move a CPU between nPars
I am sorry to say it is not possible. Moving the CPUs across Npar.
Npar behave like electrically isolated system from other Npars.
Only thing you can do is reconfiguration of Npar.

Re: Move a CPU between nPars
Howmany cell boards do you have?
Howmany CPU sockets are poulated?
Howmany cellboards allocated for each Npar?

SolutionIf you have 16 cores in total, presumably you have 2 cell boards, one for each nPar.
The granularity level of an nPar is at the cell board level, so that means each nPar here has at most 8 cores.
To make all the vPars in nPar0 have 3 cores would require 4 x 3 = 12 cores. You don't have that in the nPar.
You could of course look at combining the 2 seperate nPars into 1 big nPar with 6 vPars - although that would require you to blow away and re-cerate all the vPar definitions for one of the current nPars, but that would at least give you the flexibility to do what you are asking for. However I'd imagine there's some good reason why these vPars are in seperate nPars, and judging byt your question here, you may not have the experience/confidence to do such a major change
>> without using GiCAP
why do you think GiCAP would help you here? GiCAP is used between complexes, not within complexes.

Re: Move a CPU between nPars
Thanks for the info and we'll consider repartitioning of the vPar.

Re: Move a CPU between nPars
Thanks for your valuable response.
We have 4 Cell Boards totally and each nPars has 2 Cellboards assigned.

Re: Move a CPU between nPars
So from the details, I can understand that you have populated all the cellboards ( 4).
How many CPUs are there in each cell board?
I believe it should be 2 each . you have two options here.
1. Combine both Npar to a single one and assingn the CPUs accordingly.
2. Install more new CPUs as you have free sockets. (consult HP)
I would prefer 1st option for urgent resourse and 2nd for long term ..
:)
* iCAP is only usefull when you have enough physical CPUs..

Re: Move a CPU between nPars
The core licenses are stored in the Complex profile. If, you have 6 license cpus activated in npar1 & npar2, then you can deactivate one cpus in one of the npar & activate the in-active cpus in other npar. This will work; because when you will de-activate one cpu the profile updates as one free cpu license. And same can be used in other npar to activate the inactive cpu.

Re: Move a CPU between nPars
There are only two Inactive cores in Npar0 . and he wants 3 CPU cores atleast .
How will activate the core if there is no Physcal CPU available ??

Re: Move a CPU between nPars
There is one more option to merge these 2 npars in single npar & then can be used.
as this is rx86xx, so h/w is much stable in it's profile.
