Notes:
Not all of the SCO ‘tape’ commands will operate or be applicable to the
Seagate Viper 200 drive (execute the command ‘man tape’ for the specifics
on how the tape command works). The following tape commands are not
available for use with the Viper 200: getcomp, setcomp (the Viper 200 will
always compress the data before writing the data to tape under SCO Open
Server 5.0.x), partition, setpart, getpart, getspeed, setspeed, rsm, wsm.
The following tape commands are available for use with the Viper 200:
status, load, reset, rewind, retention, getblk, setblk, unload, eod.
When using the GUI Backup Manager utility set the block size to 32768
minimum, 65536 preferred. When using commands such as tar we suggest
using the tape command to set the block size to 512 and then using a
blocking factor of 80 for the tar command. For commands that use density
and tape size settings the tape density is 124,000 bpi and the tape length is
1800 feet.

Finding existing SCSI controllers and devices
Before installing the Seagate Viper Ultrium tape drive first ensure that the
requisite SCSI controllers and device drivers are installed on your system.
To find existing SCSI controllers execute the command:
dmesg | grep SCSI
You may see output similar to:
(scsi0)<Adaptec AHA-294XX Ultra2 SCSI host adapter> found at
PCI 0/16/0
To find existing SCSI devices execute the command:
cat /proc/scsi/scsi
You may see output similar to:
Host: scsi0 Channel: 0 Id:6 Lun:00
Vendor: SEAGATE Model: ULTRIUM06242-XXX
Type: Sequential Access ANSI SCSI Revision 03
