18 | * The code in this file is based on the SCSI to ATA Translation (SAT) | |
19 | * draft found at http://www.t10.org . The original draft used for this | |
20 | * code is sat-r08.pdf which is not too far away from becoming a | |
21 | * standard. The SAT commands of interest to smartmontools are the | |
22 | * ATA PASS THROUGH SCSI (16) and ATA PASS THROUGH SCSI (12) defined in | |
23 | * section 12 of that document. | |
24 | * | |
2127e193 GI |
25 | * sat-r09.pdf is the most recent, easily accessible draft prior to the |
26 | * original SAT standard (ANSI INCITS 431-2007). By mid-2009 the second | |
27 | * version of the SAT standard (SAT-2) is nearing standardization. In | |
28 | * their wisdom an incompatible change has been introduced in draft | |
29 | * sat2r08a.pdf in the area of the ATA RETURN DESCRIPTOR. A new "fixed | |
30 | * format" ATA RETURN buffer has been defined (sat2r08b.pdf section | |
31 | * 12.2.7) for the case when DSENSE=0 in the Control mode page. | |
32 | * Unfortunately this is the normal case. If the change stands our | |
33 | * code will need to be extended for this case. | |
34 | * | |
4d59bff9 GG |
35 | * With more transports "hiding" SATA disks (and other S-ATAPI devices) |
36 | * behind a SCSI command set, accessing special features like SMART | |
37 | * information becomes a challenge. The SAT standard offers ATA PASS | |
38 | * THROUGH commands for special usages. Note that the SAT layer may | |
39 | * be inside a generic OS layer (e.g. libata in linux), in a host | |
40 | * adapter (HA or HBA) firmware, or somewhere on the interconnect | |
41 | * between the host computer and the SATA devices (e.g. a RAID made | |
42 | * of SATA disks and the RAID talks "SCSI" to the host computer). | |
43 | * Note that in the latter case, this code does not solve the | |
44 | * addressing issue (i.e. which SATA disk to address behind the logical | |
45 | * SCSI (RAID) interface). | |

211 | // data: location to write output data, if needed (512 bytes). | |
212 | // Note: not all commands use all arguments. | |

214 | // -1 if the command failed | |
