Hi.  I've done this about 20 times in the last week, except I'm using
alt_disk_installs and mksysb's to disk.

Define a file devclass, then backup db type=full devc=fileclass
vol=/mydir/filename.  Then, on your test box, mount mydir and copy your
devconfig (or simply ftp it if you have disk space), and do a dsmserv
restore db devc=fileclass volume=filename commit=yes

Good luck,
Alex
