AMTAPE(8)                    System Manager's Manual                   AMTAPE(8)



NAME
       amtape - user interface to Amanda tape changer controls

SYNOPSIS
       amtape config command [ command options ]

DESCRIPTION
       Amtape performs tape changer control operations.  It uses the underlying
       tape changer script defined by the tpchanger option for a particular
       Amanda configuration as specified by the config argument.

       Tape changers maintain a notion of the current and next slot for each
       configuration.  These may or may not correspond to an actual physical
       state of the device, but do tend to minimize searching through the tape
       storage slots.  If the desired tape is in the current slot, it is likely
       the next tape needed is in the next slot rather than at some random
       position in the storage slots.

       See the amanda(8) man page for more details about Amanda.

COMMANDS
       reset  Reset the tape changer to a known state.  The current slot is set
              to the first slot.  Other device-specific side effects may occur.
              Some gravity stackers need to be reset to the top position by
              hand.  This command notifies Amanda the stacker is back in that
              position.

       eject  If a tape is loaded in the drive, it is ejected and returned to
              the slot from which it was loaded.

       clean  If a cleaning tape is defined for the changer, it is used to clean
              the drive.

       show   Show the contents of all slots.  This can be slow.

       label label
              Search for and load the Amanda tape with label label.

       taper  Perform the taper scan algorithm.  Load the next tape in the
              configuration's tape sequence, or a fresh tape with a suitable
              label.

       device Display the name of the current tape device on stdout.

       current
              Display the current slot.

       update Update the changer label database, if it has one, to match the
              tapes now available.

       slot slot
              Eject any tape in the drive and put it away, then load the tape
              from slot slot and reset current.

       slot current
              Eject any tape in the drive and put it away, then load the tape
              from the current slot.

       slot prev
              Eject any tape in the drive and put it away, then load the tape
              from the previous slot and reset current.

       slot next
              Eject any tape in the drive and put it away, then load the tape
              from the next slot and reset current.

       slot first
              Eject any tape in the drive and put it away, then load the tape
              from the first slot and reset current.

       slot last
              Eject any tape in the drive and put it away, then load the tape
              from the last slot and reset current.

       slot advance
              Eject any tape in the drive and put it away.  Advance current to
              the next tape, but do not load it.

              This is useful with non-gravity stackers to unload the last tape
              used and set up Amanda for the next run.  If you just use eject,
              the current tape will be mounted again in the next run, where it
              will be rejected as being still in use, ejected and the next tape
              requested.  Using slot next followed by eject does an unnecessary
              mount.

       Note: most changers optimize the slot commands to not eject the loaded
       tape if it is the one being requested.
