vPar Configuration

[Vinayagam Kannan Muruge]

Hi Friends,

I have 2 vPars in my Superdome npar and i have 2 Cpus Available not assigned to any vpar.

Vpar 1 - 4 CPU Allocated
5GB Ram Allocated
Vpar 2 - 2 CPU allocated
4 GB Ram allocated.

My requirements is

1. I want to add 1 CPU to Vpar 2 as Bound CPU by the command

vparmodify -p Vpar1 -m cpu::3 -mcpu:::3:8
shutdown -r (Vpar2)

2. I want to remove 2 GB Ram from Vpar1 and add it to Vpar 2.

Shutdown -h vpar1
Vpar2> vparmodify -p vpar1 -d mem::2048
vpar2> vparmodify -p vapar2 -a mem::2048
shutdown -r (Vpar2)

Is the commands and the procedure correct?

My doubt is in the secon instance do i need to give the amount of Mem i need to add or the total mem of 7 GB.

Pls suggest.

Hi,

according to the documentation you "ADD" memory, so your command

vpar1> vparmodify -p vpar2 -a mem::2048

will add 2GB memory to the existing amount.

Please note, you have to run this command from vPar1 when vPar2 is down.

1) you can add and remove cpus to and from vpars on the fly, no need to shutdown, obviously cpu per vpar must be > 0.

2) As mentioned, shutdown vpar1 and use vparmodify ( or gui vparmgr )from vpar2 to modify mem and vice versa.
