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.
Thanks,
Pim

I'm testing this setup

Promise V-Trak J300S SAS/SATA enclosure/expander
12x Seagate ST3500630NS
Linux kernel 2.6.21.1 x86_64
smartmontools-5.37-1.1.fc6 from Fedora Core 6
"smartctl -i -d sat /dev/sdc" gives me
Smartctl: Device Read Identity Failed
I presume /dev/sdc is an actual disk rather than a
RAID device made up of several disks. The SAT standard
(and smartmontools) don't have a general way of
addressing individual disks behind RAID infrastructure.
For recent versions of smartmontools version 5.37 and
MPT Fusion SAS HBAs this should work if /dev/sdc is
a SATA disk. Your HBA may need a firmware upgrade.
You might fetch sg3_utils version 1.24 and try:
sg_sat_identify /dev/sdc

Same with "-d ata".
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.
