Hi everyone I'm trying to send a command to a SAS (serial attached scsi) storage device to retrieve some SMART information, but I'm facing some problems that maybe you can give me some light.
During a research about how does the SAS devices work I faced this specification: http://www.t10.org/members/w_sat4.htm. My hope was to have a SCSI or ATA protocol attached to this device / controller, so I could create a SAT library and would be able to end a ATA command over the SCSI protocol, or a SCSI command over a ATA protocol (not sure about the correct option yet). After checking the handles created on this device I had a terrible surprise. No ATA_PASS_THRU protocol instance was created to it, and no SCSI_EXT_PASS_THRU protocol instance was created too. My questions are: Does anyone ever worked with SAS devices and had success with it? In case I really need to do that, seems I would need to create a SAS controller driver so I could send the command to the correct device. Am I right about this? Any other idea?
