RMAN-06033: channel string not allocated
Cause: An rman command requests a specific channel, but the requested channel has not been allocated.
Action: ALLOCATE the channel, or correct the channel identifier.

What does these messages indicate then?
Ain't channels allocated?

Or does this mean it will use allocated channel X if it is allocated?

Post the WHOLE session AND configurated parameters.

RMAN>SHOW DEVICE TYPE;
RMAN configuration parameters are:
CONFIGURE DEVICE TYPE DISK PARALLALISM 3;

In effect,rman should allocate 3 channels with default format.

RMAN will only allocate 3 channels if you have set RMAN up to allocate channels automatically or if you have allocated channels manually. It appears that you haven't done either.

What does this command set RMAN to then?

You are correct. CONFIGURE DEVICE ... PARALLALISM 3 does allocate the channels as indicated in your output above, but it doesn't allocate the channels for you to attach to them directly. In order to specify and attach to the channels you should allocate 3 channels that you create and name.
