Yes, this is only for the Falcon right now, for TT SCSI we still lack
emulation of the second MFP.

No, that command line is good. You just hit a bug: I only tested the
emulation with the default SCSI ID 0 so far (i.e. I was using the
--scsi parameter without "1="), and apparently I forgot to set the
selected SCSI ID in one of the many variables. Should be fixed now!

Note that the SCSI code is is a "marriage" of Hatari's SCSI command
emulation layer (that has only been used for ACSI so far), with the
NCR5380 and SCSI bus state emulation code from WinUAE. It already took
quite a while to make them play nice together, so you likely have to
expect some more oddities here. Did I already mention that it is still
"experimental" ;-) ?
