Re: SMART support for SATA drives in SAS enclosures
Doug, /dev/sdc is indeed a physical SATA disk. sg_sat_identify says: ATA PASS-THROUGH (16) not supported I'll look into a firmware update.

If I treat the disk as SCSI (-d scsi), the command will not fail, but wil only retrieve the serial number. With MPT Fusion SAS hardware (that I have seen) the SAT layer is in the HBA firmware. Only later versions of the firmware support the SCSI ATA PASS-THROUGH command.
