40 .Nd medium changer control utility
52 utility is used to control the operation of medium changers, such as those
53 found in tape and optical disk jukeboxes.
55 The options are as follows:
56 .Bl -tag -width indent
60 rather than the default device
64 The default changer may be overridden by setting the environment variable
66 to the desired changer device.
68 A medium changer apparatus is made up of
70 There are five element types:
80 (select by volume identifier). The
82 pseudo-element type allows the selection of tapes by their volume tag
83 (typically a barcode on the tape).
85 In this command description, the shorthand
87 will be used to represent an element type, and
89 will be used to represent an element unit.
90 For example, to represent the first robotic arm in the changer, the

101 .Ar <from ET> <from EU> <to ET> <to EU>
104 Move the media unit from
108 If the optional modifier
110 is specified, the media unit will be inverted before insertion.
112 .Ar <src ET> <src EU> <dst1 ET> <dst1 EU>
113 .Op Ar <dst2 ET> <dst2 ET>
117 Perform a media unit exchange operation. The media unit in
121 and the media unit previously in
125 In the case of a simple exchange,
127 is omitted and the values
129 are used in their place.
130 The optional modifiers
134 specify whether the media units are to be inverted before insertion into
140 Note that not all medium changers support the
142 operation; the changer must have multiple free pickers or emulate
143 multiple free pickers with transient storage.
145 .Ar <from ET> <from EU>
147 Return the media unit to its source element.
148 This command will query the status of the specified media unit, and
149 will move it to the element specified in its source attribute.
150 This is a convenient way to return media from a drive or portal
151 to its previous element in the changer.
157 Position the picker in front of the element described by
159 If the optional modifier
161 is specified, the media unit will be inverted before insertion.
163 Note that not all changers behave as expected when issued this command.
165 Report the number of slots, drives, pickers, and portals in the changer,
166 and which picker unit the changer is currently configured to use.
168 Report which picker unit the changer is currently configured to use.
172 Configure the changer to use picker

180 operation on the changer. The optional
182 parameter may be given to specify a timeout in seconds for the
183 operations. This may be used if the operation takes unusually long
184 because of buggy firmware or the like.
192 Change volume tag for an element in the media changer. This command
193 is only supported by few media changers. If it is not supported by a
194 device, using this command will usually result in an "Invalid Field in
195 CDB" error message on the console.
199 flag is specified, the volume tag of the specified element is
202 flag is specified, the volume tag is superseded with the specified
203 volume tag even if a volume tag is already defined for the element.
204 It is an error to not specify the
206 flag when trying to set a label for an element which already has
207 volume tag information defined.
209 The command works with the primary volume tag or, if the
211 flag is given, with the alternate volume tag.
216 Report the status of all elements in the changer. If
218 is specified, report the status of all elements of type
221 Print the primary volume tag for each loaded medium, if any. The volume
225 Print the alternate volume tag for each loaded medium, if any.
227 Print the additional sense code and additional sense code qualifier for
230 Print the element source address for each element.
232 Print SCSI bus information for each element. Note that this information
233 is valid only for drives.
235 Print the internal element addresses for each element. The internal
236 element address is not normally used with this driver. It is reported
237 for diagnostic purposes only.

246 Element contains a media unit.
248 Media was deposited into element by an outside human operator.
250 Element is in an abnormal state.
252 Media in this element is accessible by a picker.
254 Element supports passing media (exporting) to an outside human operator.
256 Element supports receiving media (importing) from an outside human operator.
