<p class=MsoNormal>We’ve been trying to run the ‘cmpost’
example under the libibcm project.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Here’s the scenario:<o:p></o:p></p>
<p class=MsoNormal>Device Under Test: Mellanox HCA with 2 ports. ofed-rc6 stack
installed. SM is disabled on the HCA<o:p></o:p></p>
<p class=MsoNormal>Tester Device: A test implemented on the Agilent Infiniband
Generator. Test brings up the subnet (has SM), and then sends a basic CM
Connect Request with Service ID = DTA Service ID (0x20)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Observation:<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>1.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Even when cmpost is not running, the OFED stack appears
to send a ConnectReject with reason: Invalid Service ID. So clearly it looks
like there is some kind of CM service running just on device boot up. How do we
disable this? <o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>2.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>cmpost in client mode fails to send the REQ packet<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>3.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>cmpost in server mode fails to receive a REQ
packet sent from Agilent Generator. Cmpost seems to block on
‘ib_cm_get_event’ and does not receive the incoming REQ.<o:p></o:p></p>
<p class=MsoListParagraph><o:p> </o:p></p>
<p class=MsoListParagraph>Am I missing any further hooks to the lower-level
drivers? The README under libibcm project stated that /dev/infiniband/ucm0
needs to be created. I created this using the ‘mknod’ command.
That’s about the only thing we have done before starting cmpost. <o:p></o:p></p>
