Are you using some sort of multipathing?  To check if those are two entries (really) for the same drive, test them with mt.  I haven't work with Solaris much lately, but I remember that in old days numbering used to star from 0.  In your case is 400+.  Unless you use custom names (like /dev/rmt/{bus}{target}cbn then I wouldn't be surprised if device database might have gone banana.  Without any further test to test few potential scenarios, it would be hard to say what it is.  I would start by testing if I get the response on both device names if case I load the tape.  If yes, it means both device names are valid and this might be due to multipathing.
