The 2.4 kernel has built-in SCSI support; you have to compile it in under 2.6 (legacy scsi support)
cat /proc/scsi/scsiLook for a non-"Direct Access" device. ("Direct Access" devices are hard disks.) If it's not there (for example, because the drive was connected, but powered on after boot), get the rescan-scsi-bus script:
./rescan-scsi-bus.shLook for "NEW" and/or "sequential access"
cat /proc/scsi/scsi again, and look for:Host: scsi0 Channel: 00 Id: 05 Lun: 00 Vendor: IBM Model: ULTRIUM-TD1 Rev: 25D4 Type: Sequential-Access ANSI SCSI revision: 03Device name: Will have "s" in name because it's scsi/dev/nstx= non-rewindable scsi tape/dev/stx= rewindable
x = number We want /dev/st0, the first rewindable scsi tape device.
To check drive status:mt -f /dev/st0 status
To do mindless, one-time tar backup: The first three steps may be unnecessary, depending on drive model. Ours seems to automatically rewind and you can just let tar overwrite any existing data, rather than wait for the erase step to finish -- it takes a long time to erase the whole 100 GB.mt -f /dev/st0 rewind mt -f /dev/st0 erase mt -f /dev/st0 rewind mt -f /dev/st0 lock #to prevent someone hitting eject before it's finished tar -cvzf /dev/st0 /path/to/stuff/to/back/up/ mt -f /dev/st0 unlock mt -f /dev/st0 eject
