I would like to specify my own PP size (I will later restore the image on bigger disks).
I can install fresh AIX from NIM (using lpp_source+spot and rte method) with default PP size (AIX calculates).

but even if I create customized image.data NIM resource (with desired PP size for rootvg) then the installation always fails with error:

Is image.data resource not valid for base AIX instalaltion from spot+lpp_source?
both NIM resources were made of fresh AIX 6.1 installation medias. When I install without image.data resource then whole installation process goes fine.

Any idea how to get this stuff working?
best regards, P.

ok, I think I've found a workaround

I had to install it twice:

step #1: fresh AIX installation with default PP sizes ~14 minutes
step #2: ifconfig en0 up....; mount NIM_IP:/.../mnt;mksysb -i -e -X /mnt/fresh_AIX... ~1 minute
step #3: second AIX installation from from mksysb + customized image.data ~2 minutes

and finally my base/fresh rootvg has now desired PP size

I was surprised how quickly (2 minutes) mksysb installation completed comparing to standard AIX installation (from the same NIM server but from lpp_source+spot)
