Eli,

You will firstly need to identify memory components you wish to move using vparstatus, and then deallocate using vparmodify with a -d option, and the add to required partition with vparmodify -a option.

Do you have dynamic memory?

If not, stop the first vPar, reduce the memory, start again.

Then stop second vpar, add memory and start again.

anex example:

the vpar SAPL917 has 10 GB
the vpar SAPL930 has 4 GB

I need delet 6 gb from SAPL917
The VPAR SAPL917 before change:
SAPL917 4 GB

I need add 6 GB from SAPL930
The VPAR SAPL930 before change:
SAPL930 10 GB

commands apply:
vparmodify -p SAPL917 -d cell:0:mem:6144

vparmodify -p SAPL930 -a cell:0:mem:6144

This correct?

Eli,

You are missing a colon in the vpar commands, and you can also specify FLOAT if the memory is not cell local

vparmodify -p vpar1 -d cell:6:mem::32768:FLOAT

vparmodify -p vpar2 -a cell:6:mem::32768:FLOAT

Berd

This is dynamic memory, you should read the chapter

Memory: Concepts and Functionality

in admin guide!

this change could be online?

Re: Documents Guide VPAR Manager

Torsten. — Tue, 17 Aug 2010 03:28:11 GMT

Non floating (non dynamic) memory cannot be changed online.

Re: Documents Guide VPAR Manager

Berd — Tue, 17 Aug 2010 08:27:15 GMT

Eli,

Try vparstatus -v, this will show if you have any floating memory.
