Hello !
man mc
The mc utility provides users with a command-line interface to send media manipulation commands to an autoloader or media changer device. It takes "element types" as arguments to most of the options. The valid element types (element_types) are:

D Specifies a Data Transfer (DT) element.
I Specifies an Import/Export (IE) element.
M Specifies a Medium Transport (MT) element.
S Specifies a Storage (ST) element.

So format of the command should be:
mc -p /dev/rac/c4t0d0 -s S2 -d D1
where S2 means slot #2 and D1 means tape drive #1. Don't forget to type space between option and element.
