There should be 30 Gigs of space and I don't understand where are they.
Think of "PP"s like chunks of space in your volume group. Increases or decreases in the size of your filesystems will occur in your case 128MB at a time. You can't give a filesystem 127MB or 129MB. It will increase or decrease by 128MB because that is your PP size.
It looks like you have 30 gig free.
FREE PPs: 238 (30464 megabytes)
238 PPs * 128MB PP size = 30464 MB free
Run this command to change the size of your /usr filesystem. I have mine sized around 3 gig. This command sets the /usr to 3 gig:
chfs -a size=3G /usr
If you want to want to increase, you can do 128MB (or whatever size you want) increases like this:
chfs -a size=+128M /usr
This just adds 128M to whatever is already there. If you try to increase your /usr by 1MB, it will give it another 128MB because that is your PP size.
Also, to see your filesystem sizes in a format that makes more sense, run "df -Im":
hostname:/:$ df -Im /usr
