Description martin 2014-07-07 18:16:50 UTC 
I am having problems with smartctl from smartmontools-6.2_2 failing with the message:

SMART STATUS RETURN: incomplete response, ATA output registers missing

with a SATA disk connected like this:

isci0: <Intel(R) C600 Series Chipset SAS Controller (SATA mode)> port 0x2100-0x21ff,0x2000-0x20ff mem 0x38007f800000-0x38007f807fff,0x38007f000000-0x38007f7fffff irq 26 at device 0.0 on pci3
da2 at isci0 bus 0 scbus0 target 2 lun 0
da2: <ATA ST4000NM0033-9ZM SN03> Fixed Direct Access SCSI-5 device 
da2: Serial Number             Z1Z341YS
da2: 300.000MB/s transfers
da2: Command Queueing enabled
da2: 3815447MB (7814037168 512 byte sectors: 255H 63S/T 486401C)

The machine is running 10.0-RELEASE-p6 with the isci patches r265570, r265571 and r268073 but the problem also occurs when running from FreeBSD-11.0-CURRENT-amd64-20140701-r268111-memstick-uefi.img.

I suspect a bug in the kernel or driver because the same version of smartctl works when the machine is booted from a CentOS 6.3 LiveCD.


Here is the full output from smartctl (error at the end):

$ /usr/local/sbin/smartctl -H -r ioctl,2 /dev/da2
smartctl 6.2 2014-02-18 r3874 [FreeBSD 10.0-RELEASE-p6 amd64] (local build)

This is an upstream smartctl issue. The sense data above uses the fixed format sense data format which returns ATA output registers from SAT ATA PASS-THROUGH cmd:

f0 = VALID | RESPONSE CODE: FIXED FORMAT
00 = ...
01 = ... | SENSE KEY: RECOVERED ERROR
00 = ATA ERROR register
50 = ATA STATUS register
40 = ATA DEVICE register
00 = ATA COUNT register
00 = ...
00 = ...
c2 = ATA LBA HIGH register ] SMART ...
4f = ATA LBA MID register  ] ... STATUS OK
00 = ATA LBA LOW register
00 = ASC  ] ATA PASS THROUGH ...
1d = ASCQ ] ... INFORMATION AVAILABLE
... 

This format is a late addition to (or: fix of) SAT standard and not yet detected by smartmontools.

Compatibility patch written by Jim Harris

Despite the smartctl ticket, you might consider the attached compatibility patch written by Jim Harris (see http://lists.freebsd.org/pipermail/freebsd-scsi/2014-July/006382.html), which has worked well for me in FreeBSD 10.0.
Comment 5 Oleksii Samorukov freebsd_committer freebsd_triage 2015-03-14 19:30:05 UTC 
recent commit in smartmontools project adds support for the SAT ATA PASS-THROUGH fixed format sense data. Please try to build it from SVN and report if it works.
Comment 6 martin 2015-06-19 16:11:05 UTC 
It still fails in the same way with smartctl svn.
The machine is now running unpatched 10.1-RELEASE-p13.

According to http://lists.freebsd.org/pipermail/freebsd-scsi/2014-July/006383.html on the same thread as the compatibility patch, the kernel is returning the wrong value for byte 7 in the fixed format sense data buffer, which should be 10 rather than 0.

He seems to have a good point, so it looks like sati_scsi_fixed_sense_data_construct and sati_scsi_common_fixed_sense_construct need to byte 7, like sati_scsi_common_descriptor_sense_construct and 
sati_scsi_descriptor_sense_data_construct do.

This is a production machine, so I'm not confident enough to just change this without additional input from someone who knows about this stuff in FreeBSD.

Patch to set byte 7 (ADDITIONAL SENSE LENGTH) of fixed format sense data

Here is a new patch that fixes the kernel to work with smartctl.  It also allows camcontrol to report the correct error when trying to eject the fixed disk with camcontrol eject 0:0:0 -v.

This patch does two things:

1) Sets the correct value for byte 7 (ADDITIONAL SENSE LENGTH) of the fixed format sense data in sati_scsi_fixed_sense_data_construct and sati_scsi_common_fixed_sense_construct.

2) Sets the lba fields correctly for the ATA PASS-THROUGH response in sati_passthrough_construct_sense (the bytes were in the wrong order).  This is needed for smartctl.
Comment 8 Matthew L. Dailey 2016-01-07 16:31:50 UTC 
FWIW, I think I've run into this on one of my systems running FreeBSD 10.2-RELEASE-p7 amd64 and smartctl 6.4 2015-06-04 r4109.

Unfortunately, this system is in production, so I can't try the kernel patch in this bug report, but wanted to pass along this info in case it was helpful. If I find another system exhibiting this behavior or am able to test the kernel patch on this system, I'll update again.

The hardware looks like this (from dmesg):
