Hi Brenda,

There are several commands we used to set this up:

DEFINE DBVOLUME /dev/rdsk/c2t0d0s4 FORMATSIZE=24000 WAIT=NO
DEFINE LOGVOLUME /dev/rdsk/c1t0d1s4 FORMANTSIZE=10000 WAIT=NO

They format in about a minute and we are getting an average of
about 50-60 GB/hr transfer rate. On Exchange tests we ran an
average of 80 GB/hr to back up and 39 GB/hr to restore the full
database. Remember that using raw volumes
is quick but it can EASILY get you into trouble. Make *very* sure
you have this mapped out and know *exactly* which slices you are
using and where.
