To check how much disk is free use the df Disk Free command
In this example I will expand the /home file system
Lets expand the file system for /home by using the smit chfs command
The smit command invokes the System Management Interface Tool (SMIT)
If your terminal is not setup correctly you may need to setup TERM=vt100 and try again
If term is setup correctly you can now select Change / Show File System
User down arrow keys to select filesystem you want to expand
User down arrow keys to chance filesystem SIZE and enter new size
In my example changed 32768 to 132768 and pressed Enter "Do"
Wait for filesystem to be expanded
If all goes well you should see this screen
Exit smit Escape + 0 and check df again
If you prefer you can enter the commnand directly ( and not use SMIT )
You would enter the following at the # prompt
chfs -a size='132768' /home
