[DragonFlyBSD - Bug #3243] SMART status not reported properly for SSD disks

La demande #3243 a été mise à jour par deef.


Just a minor correction... on FreeBSD, the bug was related not to iscsi driver but isci (Intel C600 Serial Attached SCSI driver).

----------------------------------------
I get this message "smartctl SMART Status not supported: Incomplete response, ATA output registers missing" when trying to use smartctl on SSDs (that don't return that message under Linux for example) using both master and release 5.8.1.

Searching a bit lead me to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=191717

So I'm wondering if something could be wrong on DragonFly's side as it seems it was on FreeBSD iscsi driver, though in my case it's not a iscsi disk.

I've ran "smartctl -H -d sat -r ioctl,2 /dev/da0" to compare and I've attached the result, the interesting part is at the end :

REPORT-IOCTL: Device=/dev/da0 Command=SMART STATUS CHECK
 Input:   FR=0xda, SC=...., LL=...., LM=0x4f, LH=0xc2, DEV=...., CMD=0xb0
 [ata pass-through(16): 85 06 2c 00 da 00 00 00 00 00 4f 00 c2 00 b0 00 ]
  CAM status=0x1, SCSI status=0x0, resid=0x0
  status=0x0
 [Duration: 0.020s]
REPORT-IOCTL: Device=/dev/da0 Command=SMART STATUS CHECK returned -1 errno=78 [Incomplete response, ATA output registers missing]
SMART Status not supported: Incomplete response, ATA output registers missing
SMART overall-health self-assessment test result: PASSED
Warning: This result is based on an Attribute check.

It looks like the answer to the STATUS CHECK command is not taken into account properly.
