RE: onstat -g rea almot 100 queue there !!!

In Response To: RE: onstat -g rea almot 100 queue there !!! (Penza Kenneth at MITTS)

RE: Set up for raw spaces in Red Hat
Here is what we use to set up raw space. The f_partition is run only
once.
The script sits in /etc/init.d and is run on reboot or when we
make a change.
