Alberto,
Peripheral device type 3 is "processor" type. It is
often used for SAF-TE targets. These are enclosure
services processors, here is a tool to look at them:

Type 0 is for disks, strange that sd didn't pick up
those devices on host 7. Could you fetch the sg3_utils
package, build it and try 'sg_inq /dev/sg6'. The output
may be interesting.
