IF I have a Logical Volume that I need to shrink, then how can I do it? [there could be several FileSystems on it...]. What is the process?

you can use chfs like :

chfs -a size=*newsize* /filesystem

For example

chfs -a size=2G /tmp

That will set /tmp to 2Gb of space

For more info take a look at chfs' man page
