hi frank,

read

http://www.mort.level5.net/johnr/howto/520rel.txt

for disc requirements.

for "shrinking" /usr i would prefer NIM.
Make a mksysb, edit the image.data to your needs (be carefull)
and try to restore it.

regards,

>-----------------------------------------------------------------------------------------------------------------------------|

Hi *,

I have 2 questions:

- Have somebody any information how much increase the rootvg when I migrate
from 4.3.3 to 5.2?

- How to restore /usr ?
I think that I need for the migration from AIX 4.3.3 to AIX 5.2 more space
in my rootvg (SP - silver wide node). In the moment I have only 96 MB free
in the rootvg. But when I check the filesystems, I observe that /usr have
933MB free.
But what is the way to reduce /usr???? I think that 'delete filesystem' and
'restore' with TSM in a smaller lv isn't possible by /usr
What can I do?
Have somebody any information how much increase the rootvg when I migrate
from 4.3.3 to 5.2?

Best regards,
Frank Mueller
