.Sh DESCRIPTION
|
||||
.Nm Chio
|
||||
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
|
||||
.Nm 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
|
||||
.Nm ET
|
||||
will be used to represent an element type, and
|
||||
.Nm 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 chio 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 chio 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>
|
||||
respecitively.
|
||||
.Pp
|
||||
Note that not all medium changers support the
|
||||
.Nm exchange
|
||||
operation; The changer must have multiple free pickers or emulate
|
||||
multiple free pickers with transient storage.
|
||||
.Pp
|
||||
.Nm chio 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 chio params
|
||||
.Pp
|
||||
Report the number of slots, drives, pickers, and portals in the changer,
|
||||
and which picker unit the changer is currently configured to use.
|
||||
.Pp
|
||||
.Nm chio getpicker
|
||||
.Pp
|
||||
Report which picker unit the changer is currently configured to use.
|
||||
.Pp
|
||||
.Nm chio setpicker
|
||||
.Ar <unit>
|
||||
.Pp
|
||||
Configure the changer to use picker
|
||||
.Pa <unit> .
|
||||
.Pp
|
||||
.Nm chio status
|
||||
.Op Ar <type>
|
||||
.Pp
|
||||
Report the status of all elements in the changer. If
|
||||
.Pa <type>
|
||||
is specified, report the status of all elements of type
|
||||
.Pa <type> .
|
||||
.Pp
|
||||
The status bits are defined as follows:
|
||||
.Bl -tag -width indent
|
||||
.It Nm FULL
|
||||
Element contains a media unit.
|
||||
.It Nm IMPEXP
|
||||
Media was deposited into element by an outside human operator.
|
||||
.It Nm EXCEPT
|
||||
Element is in an abnormal state.
|
||||
.It Nm ACCESS
|
||||
Media in this element is accessible by a picker.
|
||||
.It Nm EXENAB
|
||||
Element supports passing media (exporting) to an outsite human operator.
|
||||
.It Nm INENAB
|
||||
Element supports receiving media (importing) from an outside human operator.
|
||||
.El
|
||||
.Pp
|
||||
.Sh EXAMPLES
|
||||
.Nm chio move slot 3 drive 0
|
||||
.Pp
|
||||
Moves the media in slot 3 (fourth slot) to drive 0 (first drive).
|
||||
.Pp
|
||||
.Nm chio setpicker 2
|
||||
Configures the changer to use picker 2 (third picker) for operations.
