I just checked it on my own system with SATA disks. scsi_id uses page
0x83 in the scsi inquery command by default which only returns the
"Linux ATA-SCSI simulator" string, but no identification. scsi_id
prepends the type (ATA) and the model string to the returned value. My
real fiber channel (scsi) disks returns the wwnn number there.

Using the page 0x80 also uses the serial number for sata devices. You
can use them be adding "-p 0x80" to the command line.
