How to identify the tape drive's device file name in hal-device's output

[YangKun]

Hi Fellows,

Can anyone point me out how can I tell the tape drive's device file name 
from the related section of hal-device's output below :
------------------------------------------------------------------
udi = 
'/org/freedesktop/Hal/devices/pci_9005_c0_0_scsi_host_scsi_device_lun0'
  info.udi = 
'/org/freedesktop/Hal/devices/pci_9005_c0_0_scsi_host_scsi_device_lun0'  
(string)
  linux.subsystem = 'scsi'  (string)
  linux.hotplug_type = 1  (0x1)  (int)
  scsi.type = 'tape'  (string)
  scsi.vendor = 'HP'  (string)
  scsi.model = 'Ultrium 1-SCSI'  (string)
  info.product = 'SCSI Device'  (string)
  info.linux.driver = 'st'  (string)
  scsi.lun = 0  (0x0)  (int)
  scsi.target = 4  (0x4)  (int)
  scsi.bus = 0  (0x0)  (int)
  scsi.host = 2  (0x2)  (int)
  info.parent = '/org/freedesktop/Hal/devices/pci_9005_c0_0_scsi_host'  
(string)
  info.bus = 'scsi'  (string)
  linux.sysfs_path_device = 
'/sys/devices/pci0000:00/0000:00:1e.0/0000:05:04.0/host2/target2:0:4/2:0:4:0'  
(string)
  linux.sysfs_path = 
'/sys/devices/pci0000:00/0000:00:1e.0/0000:05:04.0/host2/target2:0:4/2:0:4:0'  
(string)

------------------------------------------------------------------

I mean , the name should be  /dev/st{digit} . But how can I find the 
"digit" from the above output ?


Thank you very much :-)
