Have you tried unplugging the DSSI disks one at a time to find their ID's?
If you don't have an operator control panel for the disks, with a 10-conductor
ribbon cable
going from the OCP to each disk, you'll have to jumper the disks to a unique ID.

The OCP typically has plastic plugs to set the ID of the individual disks.

IIRC, the DSSI controller shows up as ID 7, with the other ID's (0-6) available for
devices....
