AMTAPE(8)						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 corre-
       spond to an actual physical state of the	 device,  but  do
       tend  to minimize searching through the tape rack.  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 rack.

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

COMMANDS
       reset  Reset  the  tape	changer	 to  a	known  state.  It
	      changes the current slot to the first slot and  may
	      have  other  device-specific  side  effects.   Some
	      gravity stackers need to be reset to the top  posi-
	      tion  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.

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

       label label
	      Search for and  load  an	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 Print  the  name of the current tape device to std-
	      out.

       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 cur-
	      rent.

       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 cur-
	      rent.

       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
	      need  to be mounted again in the next run, where it
	      will be rejected as being in use, ejected	 and  the
	      next  tape  requested.  Using slot next followed by
	      eject does an unnecessary mount.

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