EXCHANGE MEDIUM MC command A6h
The EXCHANGE MEDIUM medium-changer command provides a means to exchange the medium
in the source element, with the medium located at a destination element.
The medium in the source element is moved to the first destination element and the medium that pre-
viously occupied the first destination element is moved to the second destination element. The sec-
ond destination element may or may not be the same element as the source element. In the case of a
simple exchange, the source element and the second destination element are the same.
This device can emulate the capability of handling two units of media at the same time. The ACL
cannot perform exchange medium operations. The FACL can perform an exchange medium opera-
tions if the tape unit is empty.
