SUMMARY: Disksuite - concatenation

Thanks everyone who responded especially
Matthew.Stier@fnc.fujitsu.com
This procedure basically worked. The only difficulty I had was unmounting
the file system. Even after I shut down oracle and samba it kept saying
/file_system busy. fuser -k /file_system didn't have any effect. Finally I
had to do a "init 1" to accomplish the unmount.
