|

.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
|
|
.Ar 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
|
|
.Em elements .
|
|
There are five element types:
|
|
.Em picker
|
|
(medium transport),
|
|
.Em slot
|
|
(storage),
|
|
.Em portal
|
|
(import/export),
|
|
.Em drive
|
|
(data transfer), and
|
|
.Em voltag
|
|
(select by volume identifier). The
|
|
.Em voltag
|
|
pseudo-element type allows the selection of tapes by their volume tag
|
|
(typically a barcode on the tape).
|
|
.Pp
|
|
In this command description, the shorthand
|
|
.Em ET
|
|
will be used to represent an element type, and
|
|
.Em EU
|
|
will be used to represent an element unit.
|
|
For example, to represent the first robotic arm in the changer, the
|
|
.Em ET
|
|
would be
|
|
.Dq picker
|
|
and the
|
|
.Em EU
|
|
would be
|
|
.Dq 0 .
|
|
.Sh SUPPORTED COMMANDS
|
|
.Bl -tag -width indent
|
|
.It Ic move Xo
|
|
.Ar <from ET> <from EU> <to ET> <to EU>
|
|
.Op Cm inv
|
|
.Xc
|
|
Move the media unit from
|
|
.Ar <from ET/EU>
|
|
to
|
|
.Ar <to ET/EU> .
|
|
If the optional modifier
|
|
.Cm inv
|
|
is specified, the media unit will be inverted before insertion.
|
|
.It Ic exchange Xo
|
|
.Ar <src ET> <src EU> <dst1 ET> <dst1 EU>
|
|
.Op Ar <dst2 ET> <dst2 ET>
|
|
.Op Cm inv1
|
|
.Op Cm inv2
|
|
.Xc
|
|
Perform a media unit exchange operation. The media unit in
|
|
.Ar <src ET/EU>
|
|
is moved to
|
|
.Ar <dst1 ET/EU>
|
|
and the media unit previously in
|
|
.Ar <dst1 ET/EU>
|
|
is moved to
|
|
.Ar <dst2 ET/EU> .
|
|
In the case of a simple exchange,
|
|
.Ar <dst2 ET/EU>
|
|
is omitted and the values
|
|
.Ar <src ET/EU>
|
|
are used in their place.
|
|
The optional modifiers
|
|
.Cm inv1
|
|
and
|
|
.Cm inv2
|
|
specify whether the media units are to be inverted before insertion into
|
|
.Ar <dst1 ET/EU>
|
|
and
|
|
.Ar <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.
|
|
.It Ic return Xo
|
|
.Ar <from ET> <from EU>
|
|
.Xc
|
|
Return the media unit to its source element.
|
|
This command will query the status of the specified media unit, and
|
|
will move it to the element specified in its source attribute.
|
|
This is a convenient way to return media from a drive or portal
|
|
to its previous element in the changer.
|
|
.Pp
|
|
.It Ic position Xo
|
|
.Ar <to ET> <to EU>
|
|
.Op Cm inv
|
|
.Xc
|
|
Position the picker in front of the element described by
|
|
.Ar <to ET/EU> .
|
|
If the optional modifier
|
|
.Cm inv
|
|
is specified, the media unit will be inverted before insertion.
|
|
.Pp
|
|
Note that not all changers behave as expected when issued this command.
|
|
.It Ic params
|
|
Report the number of slots, drives, pickers, and portals in the changer,
|
|
and which picker unit the changer is currently configured to use.
|
|
.It Ic getpicker
|
|
Report which picker unit the changer is currently configured to use.
|
|
.It Ic setpicker Xo
|
|
.Ar <unit>
|
|
.Xc
|
|
Configure the changer to use picker
|
|
.Ar <unit> .
|
|
.Pp
|
|
.It Ic ielem Xo
|
|
.Op Ar <timeout>
|
|
.Xc
|
|
Perform an
|
|
.Em INITIALIZE ELEMENT STATUS
|
|
operation on the changer. The optional
|
|
.Ar <timeout>
|
|
parameter may be given to specify a timeout in seconds for the
|
|
operations. This may be used if the operation takes unusually long
|
|
because of buggy firmware or the like.
|
|
.It Ic voltag Xo
|
|
.Op Fl fca
|
|
.Ar <ET>
|
|
.Ar <EU>
|
|
.Op Ar <label>
|
|
.Op Ar <serial>
|
|
.Xc
|
|
Change volume tag for an element in the media changer. This command
|
|
is only supported by few media changers. If it is not supported by a
|
|
device, using this command will usually result in a "Invalid Field in
|
|
CDB" error message on the console.
|
|
.Pp
|
|
If the
|
|
.Fl c
|
|
flag is specified, the volume tag of the specified element is
|
|
cleared. If the
|
|
.Fl f
|
|
flag is specified, the volume tag is superseded with the specified
|
|
volume tag even if a volume tag is already defined for the element.
|
|
It is an error to not specify the
|
|
.Fl f
|
|
flag when trying to set a label for an element which already has
|
|
volume tag information defined.
|
|
.Pp
|
|
The command works with the primary volume tag or, if the
|
|
.Fl a
|
|
flag is given, with the alternate volume tag.
|
|
.It Ic status Xo
|
|
.Op Fl vVsSbIa
|
|
.Op Ar <type>
|
|
.Xc
|
|
Report the status of all elements in the changer. If
|
|
.Ar <type>
|
|
is specified, report the status of all elements of type
|
|
.Ar <type> .
|
|
.It Fl v
|
|
Print the primary volume tag for each loaded medium, if any. The volume
|
|
tag is printed as
|
|
.Dq <LABEL:SERIAL> .
|
|
.It Fl V
|
|
Print the alternate volume tag for each loaded medium, if any.
|
|
.It Fl s
|
|
Print the additional sense code and additional sense code qualifier for
|
|
each element.
|
|
.It Fl S
|
|
Print the element source address for each element.
|
|
.It Fl b
|
|
Print SCSI bus information for each element. Note that this information
|
|
is valid only for drives.
|
|
.It Fl I
|
|
Print the internal element addresses for each element. The internal
|
|
element address is not normally used with this driver. It is reported
|
|
for diagnostic purposes only.
|
|
.It Fl a
|
|
Print all additional information (as in
|
|
.Fl vVsSba
|
|
).
|
|
.El
|
|
