[ale] multi-processor vs. Tape Drive

[James McFarland]

When I  use "modprobe st "It shows up under lsmod.  However, the device (/dev/st0) is not available.  Do I need to create it manually?  If so, can you point to someplace with the appropriate instructions?

It also isn't present under /proc/scsi/scsi:

SMP Kernel:
[root at pheonix ~]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: ADAPTEC  Model: oldmail-RAID5    Rev: V1.0
  Type:   Direct-Access                    ANSI SCSI revision: 02


SP Kernel:
[root at pheonix ~]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: ADAPTEC  Model: oldmail-RAID5    Rev: V1.0
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi0 Channel: 02 Id: 06 Lun: 00
  Vendor: QUANTUM  Model: DLT VS160        Rev: 2500
  Type:   Sequential-Access                ANSI SCSI revision: 02
