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.
