Additionally, Lenovo did some work that might help on the KNL discovery in general. I don't have a good memory of what we did off hand, but our self-booting KNL nodes are fine with current xCAT release for discovery and all.

In the 2.12.1, xCAT shipped a new command 'xcatprobe discovery' which an be used to monitoring the discovery process.

Normally, after discovery has occurred, the Genesis program will display a prompt on the node console saying ‘xCAT Genesis running on <hostname>”. That did not happen. Instead, the process apparently timed out on the KNL, and restarted. This repeats indefinitely. Q – Is there a way to get a log from the nodediscover program? 3 - Since the MAC address was updated in the xCAT data base, I tried doing a nodeset and reboot. The node does not respond to rpower. I rebooted manually, and it began loading an OS. I believe it is the OS I chose in nodeset, which is working an RHEL 7.2 that works fine on other machines. But I can’t be sure, because it is hung in the startup process. 4 – [root@sfs-head ~]# lsxcatd -a Version 2.9.1 (git commit 7f6043fffd62d482931b17b60f9488eb5754fdc1, built Thu Mar 19 03:25:35 EDT 2015) This is a Management Node dbengine=SQLite From: Xiao Peng Wang [mailto:[email protected]] Sent: Wednesday, July 27, 2016 5:09 PM To: [email protected]<mailto:[email protected]> Cc: [email protected]<mailto:[email protected]> Subject: Re: [xcat-user] xCAT and Knights Landing Xeon Phi xCAT team does not have experience to handle the 'Knight Landing' processor. Base on your description, looks like you were using the server which installed the bootable 'Knight Landing' processor, am I right? Did you try to use xCAT to do a general OS installation for the 'Knight Landing' server? For your scenario, since the mac has been collected, could you run the 'nodeset' against the node and perform an OS deployment to see what will happen. Please run 'lsxcatd -a' to show your xCAT version.

I am currently trying to use node discovery to configure one of them. After enabling legacy PXE, I reboot and it displays Intel Boot Agent GE v1.5.78 When it displays “beginning discovery process”, I run nodediscoverstart on our xCAT server. After a while, the correct MAC address is inserted in the xCAT database for the node. But the node never displays the usual message, “xCAT Genesis running on f078”. Instead, it loops and restarts the discovery process. I am wondering if this process is supported on KNL.
