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 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 cur­
              rent 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 std­
              out.

       current
              Display the current slot.

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

              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
              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.
