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 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 con‐
figuration'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.
