NIM "PULL" mksysb to smaller disk

[jkc924]

I have been tasked to take a mksysb of a client on my NIM server and pull it over to another server - Problem is that the mksysb was created on a server with 72 GB internal drives and I am trying to pull it over to 36 GB drives. Keep getting "not enough partition/space errors" when it is trying to create the rootvg filesystems - Is this even possible to do or do the drives on both servers have to be the same size?
Thanks in advance for any advice.

It's possible, but you have to hack the bosinst.data file as per this IBM site

Note the target disk data stanza.

Briefly the process is
[ol]
[li]Create mksysb image using NIM[/li]
[li]Edit bosinst.data as required[/li]
[li]Add bosinst.data to NIM[/li]
[li]Use NIM to push out mysysb image and bosinst.data[/li]
[/ol]
Godd luck.

I had a modified bosinst.data file as follows and it did not work:
CONSOLE = Default
INSTALL_METHOD = overwrite
PROMPT = no
EXISTING_SYSTEM_OVERWRITE = yes

RUN_STARTUP = yes
RM_INST_ROOTS = no
ERROR_EXIT =

OK, back to basics, you are sure that you haven't defined more than 36Gb of file systems in the rootvg of the source machine?

Asuming the answer is no check the image.data file and the logical volume policy stanza

It's the image.data file that contains PP, LP, and COPIES as well as the other relevant information that needs to be edited.

The file is created by mkszfile. Don't make an exact map.

But the problem is going from 72 to 36. Not recommeded. It may work but if there are problems then you no it didn't.

If there are 2 copies in image.data reduce it to one copy, one source disk, halve the PP.
