Frank,

host->max_id (max scsi target ID's) is set to TW_MAX_UNITS_9650SE for
your adapter, which is 32.

The firmware srl (spec revision level) for your 9650 adapter doesn't
support luns > (0 .. 16).

You could run in this mode but it hasn't been tested, and I don't
recall what the ramifications may be (if any).
