amtape − Control Amanda changers

amtape [−o configoption...] config subcommand

     Amtape is the command−line interface to Amanda's tape
changers (amanda‐changers(7)) and to the taperscan algorithm

     Tape changers maintain a notion of the current slot for
each configuration. This may or may not correspond to an
actual physical state of the device, but is used by some
taperscan algorithms to minimize searching through the

     Amtape uses the default changer. To use a different
changer, use the config override option, e.g.,

     Call the changer create method, it create the vtape
     root dirtectory or the s3 bucket.

     label label
     Search for and load the Amanda tape with label [label],
     also setting the current slot.

     slot slot [drive drive]
     Load the volume in the given slot, also setting the
     current slot. The slot names current, next, first, and
     last have special meaning.

     Shorthand for slotcurrent.

     Show the contents of all slots, based on the changer's
     cached metadata. This is a quick operation as it does
     not load or unload any volumes, but is not supported by
     all changers.

     show [slots]
     Show the contents of all slots (or listed slots) by
     loading each slot and reading its label. This can be
     very slow. The slots arguments is of the form 1,3−5,7.

     Reset the changer to a known state. This subcommand is
     intended to clear any unknown and potentially incorrect
     state the changer may have stored.


     eject [drive]
     Eject the tape currently in the drive. This only
     applies to some changers. Specify a drive (by drive
     number) if more than one drive is available.

     clean [drive]
     If a cleaning tape is defined for the changer, used it
     to clean the specified drive. The [drive] is optional
     if the changer only has one drive.

     sync the catalog with a device that support it,

     Run the taperscan algorithm (see amanda‐taperscan(7)),
     displaying information about the progress of the scan.

     update [what]
     Update changer state. Consult amanda‐changers(7) for
     changer−specific details on the format of what.

     Verify the changer is correctly configured. Can be
     useful for chg−robot and chg−ndmp.

     −o configoption
