<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">Ray,
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">We’ve run into the following issue with the latest OFA driver.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">During initialization, the driver request for NVME Identify Namespace fails with a status of “invalid field in command”. Because of this, initialization fails
and the device does not show up. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">The underlying cause is that the driver puts the controller ID value into CDW10.CNTID. A</span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">ccording
to the NVMe spec, that is only valid when CNS = 0x12 or 0x13. For all other cases, “the host shall clear this field to 0h”<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">I’d like to make a patch for this. The fix would remove controller ID from any of the instance of NVMe Identify command (the driver does not use CNS = 0x12 or 0x13). How would
you like me to proceed to coordinate with the current 1.5 testing?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Thanks,</span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext"><o:p></o:p></span></p>
