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 po-
       sition 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 con-
              figuration’s  tape sequence, or a fresh tape with a suitable la-
              bel.


       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.
