AMTAPE(8)AMTAPE(8)NAMEamtape - user interface to Amanda tape changer controls
SYNOPSISamtape 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.

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
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.
