chio move <from ET> <from EU> <to ET> <to EU> [
inv]
Moves the media unit from
<from ET/EU> to
<to ET/EU>. If the optional modifier
inv is specified, the media unit will be inverted before insertion.
chio exchange <src ET> <src EU> <dst1 ET> <dst1 EU> [
<dst2 ET> <dst2 ET>] [
inv1] [
inv2]
Performs a media unit exchange operation. The media unit in
<src ET/EU> is moved to
<dst1 ET/EU> and the media unit previously in
<dst1 ET/EU> is moved to
<dst2 ET/EU>. In the case of a simple exchange,
<dst2 ET/EU> is omitted and the values
<src ET/EU> are used in their place. The optional modifiers
inv1 and
inv2 specify whether the media units are to be inverted before insertion into
<dst1 ET/EU> and
<dst2 ET/EU> respectively.
Note that not all medium changers support the
exchange operation; The changer must have multiple free pickers or emulate multiple free pickers with transient storage.
chio position <to ET> <to EU> [
inv]
Position the picker in front of the element described by
<to ET/EU>. If the optional modifier
inv is specified, the media unit will be inverted before insertion.
Note that not all changers behave as expected when issued this command.
chio params

chio getpicker

chio setpicker <unit>

chio status [
<type> [unit [count]]] [
voltags]
Report the status of all elements in the changer. If
<type> is specified, report the status of all elements of type
<type>.
The status bits are defined as follows:
FULL
Element contains a media unit.
IMPEXP
Media was deposited into element by an outside human operator.
EXCEPT

ACCESS
Media in this element is accessible by a picker.
EXENAB
Element supports passing media (exporting) to an outside human operator.
INENAB

If the element is a drive, the device name of the drive will be reported if it is available.
If the [
voltags] option is specified, primary and alternate volume tag information will be reported, if available.
If the previous location of the media is available, it will also be reported.
chio ielem

INITIALIZE ELEMENT STATUS operation on the changer.
chio cdlu <sub-command> <slot>

abort
