.Sh DESCRIPTION
|
|
.Nm
|
|
is used to control the operation of medium changers, such as those found
|
|
in tape and optical disk jukeboxes.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl f Ar changer
|
|
Use the device
|
|
.Pa changer
|
|
rather than the default device
|
|
.Pa /dev/ch0 .
|
|
.El
|
|
.Pp
|
|
The default changer may be overridden by setting the environment variable
|
|
.Ev CHANGER
|
|
to the desired changer device.
|
|
.Pp
|
|
A medium changer apparatus is made up of
|
|
.Pa elements .
|
|
There are four element types:
|
|
.Pa picker
|
|
(medium transport),
|
|
.Pa slot
|
|
(storage),
|
|
.Pa portal
|
|
(import/export), and
|
|
.Pa drive
|
|
(data transfer). In this command description, the shorthand
|
|
.Ic ET
|
|
will be used to represent an element type, and
|
|
.Ic EU
|
|
will be used to represent an element unit. For example, to represent
|
|
the first robotic arm in the changer, the ET would be
|
|
.Dq picker
|
|
and the EU would be
|
|
.Dq 0 .
|
|
.Pp
|
|
.Sh SUPPORTED COMMANDS
|
|
.Nm
|
|
.Ic move
|
|
.Ar <from ET> <from EU> <to ET> <to EU>
|
|
.Op Ar inv
|
|
.Pp
|
|
Moves the media unit from
|
|
.Pa <from ET/EU>
|
|
to
|
|
.Pa <to ET/EU> .
|
|
If the optional modifier
|
|
.Pa inv
|
|
is specified, the media unit will be inverted before insertion.
|
|
.Pp
|
|
.Nm
|
|
.Ic exchange
|
|
.Ar <src ET> <src EU> <dst1 ET> <dst1 EU>
|
|
.Op Ar <dst2 ET> <dst2 ET>
|
|
.Op Ar inv1
|
|
.Op Ar inv2
|
|
.Pp
|
|
Performs a media unit exchange operation. The media unit in
|
|
.Pa <src ET/EU>
|
|
is moved to
|
|
.Pa <dst1 ET/EU>
|
|
and the media unit previously in
|
|
.Pa <dst1 ET/EU>
|
|
is moved to
|
|
.Pa <dst2 ET/EU> .
|
|
In the case of a simple exchange,
|
|
.Pa <dst2 ET/EU>
|
|
is omitted and the values
|
|
.Pa <src ET/EU>
|
|
are used in their place.
|
|
The optional modifiers
|
|
.Pa inv1
|
|
and
|
|
.Pa inv2
|
|
specify whether the media units are to be inverted before insertion into
|
|
.Pa <dst1 ET/EU>
|
|
and
|
|
.Pa <dst2 ET/EU>
|
|
respectively.
|
|
.Pp
|
|
Note that not all medium changers support the
|
|
.Ic exchange
|
|
operation; The changer must have multiple free pickers or emulate
|
|
multiple free pickers with transient storage.
|
|
.Pp
|
|
.Nm
|
|
.Ic position
|
|
.Ar <to ET> <to EU>
|
|
.Op Ar inv
|
|
.Pp
|
|
Position the picker in front of the element described by
|
|
.Pa <to ET/EU> .
|
|
If the optional modifier
|
|
.Pa inv
|
|
is specified, the media unit will be inverted before insertion.
|
|
.Pp
|
|
Note that not all changers behave as expected when issued this command.
|
|
.Pp
|
|
.Nm
|
|
.Ic params

|
|
Loads the media from the specified slot into the CD-ROM drive.
|
|
