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 particu- lar 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 posi- tion. 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. AUTHOR

NAME
amtape - Control Amanda changers SYNOPSIS
amtape [-o configoption...] config subcommand [subcommand_options...] DESCRIPTION
Amtape is the command-line interface to Amanda's tape changers (amanda-changers(7)) and to the taperscan algorithm (amanda-taperscan(7)). 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 slots. Amtape uses the default changer. To use a different changer, use the config override option, e.g., -otpchanger=otherchanger. SUBCOMMANDS
label label Search for and load the Amanda tape with label [label], also setting the current slot. slot slot Load the volume in the given slot, also setting the current slot. The slot names current, next, first, and last have special meaning. current Shorthand for slot current. inventory 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 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. taper 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. -o configoption See the "CONFIGURATION OVERRIDE" section in amanda(8). SEE ALSO
