Viper 200 Installation Manual
Configuring for Linux
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
Type: Sequential Access
Revision 03
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.
