Thank you so much Mark for your advice and indeed when I run “makedhcp -q computenode” it works successfully. How can fix the error that I get with the test?
Thank you for all your help.

Then "makedhcp xcatmntest" command is ran to update the DHCP configuration file. After that, "makedhcp -q xcatmntest" command is ran to query the xcatmntest node and verify the same ip and mac are returned. For some reason on your system "makedhcp -q xcatmntest" does not return anything and generic "DHCP server reply is wrong" message is returned. You can run "makedhcp -q" against some of your real nodes and verify correct IP and MAC are retuned for them. If so, you can ignore this xcatprobe failure.
