.Nd medium changer control utility | ||
.Sh SYNOPSIS | ||
.Nm chio | ||
.Op Fl f Ar changer | ||
.Ar command | ||
.Ar arg1 | ||
.Ar arg2 | ||
.Oo | ||

.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. | ||
