Thanks for the reply.

I labeled the tapes when I created a vtape test envirement. when I run amlabel 
I get the message : amlabel: label Backup-012 already on a tape.

my amanda.conf file is configured as this :

tpchanger "chg-disk"            # the tape-changer glue script
tapedev "file://space/vtapes/Backup/slots"      # the no-rewind tape device to 
be used
#tapetype "HP Ultrium 3-SCSI"
#changerfile "/etc/amanda/Backup/changer"
#changerfile "/etc/amanda/Backup/changer-status"
changerfile "/etc/amanda/Backup/changer.conf"
changerdev "/dev/null"

when I change tapedev to "dev/nst0''  I get error message (amlabel: could not 
load slot "current": Virtual-tape directory dev/nst0 does not exist.)



This the output of scsi device in proc/scsi: 
sh-3.2$ cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: HP       Model: Ultrium 3-SCSI   Rev: D22D
  Type:   Sequential-Access                ANSI SCSI revision: 03


when I run amtapetype -f /dev/nst0 it gives me the following:

sh-3.2$ amtapetype -f /dev/nst0
