Jie - The key to it might involve the kind of adapter to which the 3996
      was attached in the former system.  I gather that the 3996 is an
old product, so I wonder if it used a narrow SCSI interface, as opposed
to the wide that the 6204 is.  I once had to connect a rack-mount HP 3420
tape drive to a differential-wide adapter, and got it to work only by
going into SMIT and forcing the adapter to Narrow mode.  (Modern SCSI
devices should cause the adapter to lapse into narrow mode via detection,
but it's pot-luck with older devices.)  I'd recommend getting the specs
from your 3996 manual and try making the adapter suit its needs.
I don't know if the 3996 needs any special device driver software beyond
that, which would be a further complication.
