Read the device's sense data and dump them in a hex- dump format.
pos slot
Positions the autochanger transport mechanism in front of the specified slot. This
operation is only meaningful if the specified slot refers to an import/export, data
drive or repository element. The actual meaning of this operation may differ
among different autochanger models. This command is generally not required,
but is provided for testing purposes and convenience. Both physical as well as
symbolic slot addressing may be used.
move source_slot destination_slot [0 | 1]
Moves a medium from a source slot into a destination slot. This command has
two mandatory arguments, the source and destination slot IDs (address numbers,
as reported by the addr command described above) and an optional numeric
Boolean argument which can be used to instruct the robotics to flip the medium
before inserting it into the destination slot. By default (if no flipping argument is
specified), flipping is disabled.
Note that when move command is issued to move a tape into a drive, it takes
a certain time (around 30 seconds) for the drive to become online, because tape
load and calibration/selftest have to be performed. The command prompt
however, returns immediately after the command is issued.
NOTE: Flipping is supported only for double-sided optical media. For tapes, the
effect of the flip command is not defined.
NOTE: Most autochanger do not allow you to move a tape from a drive to a
repository location if the tape has not been dismounted and ejected by the drive.
You might want to use the offl command on the drive device file/SCSI address
to put the drive off-line before executing the move command.
stat [{slot | drive | transport_element | mail_slot}]
Queries the device for information about the state of each of its addressable
elements. The output of this command is a table of physical and symbolic element
IDs and their states, indicating which elements are free (Empty) and occupied
(Full).
Additionally, if barcode support is available and enabled, the barcode for each
medium is displayed.
The uma command recognizes one specific environment variable which can be
used to enable barcode support for autochangers which are equipped with
barcode reading hardware. By default, uma barcode support is disabled. It can
be enabled by exporting/setting the OB2BARCODE=1 environment variable
before starting the command or by using the -barcode option.
