You can identify SAS drives in an enclosure if the drive and enclosure 
provide the information needed.

If you issue an INQUIRY EVPD read of page 0x83 on the drive it should 
give you the WWN and target SAS addresses of the drive. You should then 
be able to tie this up with the array element in the enclosure by 
matching it up with data in the SES diagnostic page 0xA from the enclosure.

sg3_utils provides command line tools that can perform these queries.
