Storage Device Interface (SDI) medium changer target driver
The mc01 medium changer target driver is the device-level
driver for Small Computer System Interface (SCSI) medium changers.
SCSI Medium Changers mechanize the movement of media to and from
primary devices (such as disk or tape drives) and other locations
within the medium changer (magazines).
command provides command-line access to
the mc01 target driver.
This command allows the user to load, unload, position,
initialize device status, and display the current device status.
The special device files in the /dev/mc directory are used to access

is the number, starting with 1, of the associated medium
changer. There is one special file of this form for each medium
changer attached to the system.
is the occurrence of the host adapter board in the system
(that is, card number)
is the bus number
is the target controller number
is the logical unit number of the medium changer
mc01 device nodes
The device nodes in the /dev/mc
directory provide access to SCSI medium changers
attached and recognized by the system:
SCSI Bus Number
SCSI Target ID
SCSI Logical Unit Number
The changer number. The changers are numbered
sequentially starting at 1 as they are found by
calls that are supported by this driver
