You must have at least one SCSI tape drive attached to the
SCSI port of your system to back up and restore
data using SCO ARCserve/Open.
NOTE:
See the SCO Hardware Compatibility Handbook
on the SCO World Wide Web page (www.sco.com)
for the list of currently supported tape devices.
SCO ARCserve/Open allows you to ``group''
drives so that you can take advantage of Tape Cascading
and Parallel Streaming:
Tape Cascading allows jobs to span to the tape in the next drive
when one tape fills up. For a job to span to another drive,
both drives must be in the same group.
Parallel streaming allows two or more jobs to run at the same time.
To run two jobs at the same time, you must have at least two drives,
each in a separate group.
By default, each drive is placed into a separate group.
These default groups are named after the planets in our solar
system, excluding Earth. (The planets are Mercury, Venus, Mars,
Jupiter, Saturn, Uranus, Neptune, and Pluto.)
Therefore, if you have two drives, one with SCSI ID 2
and one with SCSI ID 3, SCO ARCserve/Open
sets up two groups called ``MARS''
and ``JUPITER''. You can then modify these
tape group assignments and names
using the SCO ARCserve/Open Device Manager.
