47: .Sh DESCRIPTION
1.2 lukem 48: .Nm
1.1 thorpej 49: is used to control the operation of medium changers, such as those found
50: in tape and optical disk jukeboxes.
51: .Pp
52: The options are as follows:
53: .Bl -tag -width indent
54: .It Fl f Ar changer
55: Use the device
56: .Pa changer
57: rather than the default device
58: .Pa /dev/ch0 .
59: .El
60: .Pp
61: The default changer may be overridden by setting the environment variable
1.2 lukem 62: .Ev CHANGER
1.1 thorpej 63: to the desired changer device.
64: .Pp
65: A medium changer apparatus is made up of
66: .Pa elements .
67: There are four element types:
68: .Pa picker
69: (medium transport),
70: .Pa slot
71: (storage),
72: .Pa portal
73: (import/export), and
74: .Pa drive
1.14 wiz 75: (data transfer).
76: In this command description, the shorthand
1.2 lukem 77: .Ic ET
1.1 thorpej 78: will be used to represent an element type, and
1.2 lukem 79: .Ic EU
1.14 wiz 80: will be used to represent an element unit.
81: For example, to represent
1.1 thorpej 82: the first robotic arm in the changer, the ET would be
83: .Dq picker
84: and the EU would be
85: .Dq 0 .

1.1 thorpej 94: to
1.13 ross 95: .Pa \*[Lt]to ET/EU\*[Gt] .
1.1 thorpej 96: If the optional modifier

1.1 thorpej 104: .Op Ar inv1
105: .Op Ar inv2
106: .Pp
1.14 wiz 107: Performs a media unit exchange operation.
108: The media unit in
1.13 ross 109: .Pa \*[Lt]src ET/EU\*[Gt]
1.1 thorpej 110: is moved to
1.13 ross 111: .Pa \*[Lt]dst1 ET/EU\*[Gt]
1.1 thorpej 112: and the media unit previously in
1.13 ross 113: .Pa \*[Lt]dst1 ET/EU\*[Gt]
1.1 thorpej 114: is moved to
1.13 ross 115: .Pa \*[Lt]dst2 ET/EU\*[Gt] .
1.1 thorpej 116: In the case of a simple exchange,
1.13 ross 117: .Pa \*[Lt]dst2 ET/EU\*[Gt]
1.1 thorpej 118: is omitted and the values
1.13 ross 119: .Pa \*[Lt]src ET/EU\*[Gt]
1.1 thorpej 120: are used in their place.
121: The optional modifiers
122: .Pa inv1
123: and
124: .Pa inv2
125: specify whether the media units are to be inverted before insertion into
1.13 ross 126: .Pa \*[Lt]dst1 ET/EU\*[Gt]
1.1 thorpej 127: and
1.13 ross 128: .Pa \*[Lt]dst2 ET/EU\*[Gt]
1.4 hubertf 129: respectively.
1.1 thorpej 130: .Pp
131: Note that not all medium changers support the
1.2 lukem 132: .Ic exchange
1.1 thorpej 133: operation; The changer must have multiple free pickers or emulate
134: multiple free pickers with transient storage.

1.1 thorpej 143: If the optional modifier
144: .Pa inv
145: is specified, the media unit will be inverted before insertion.
