Hi Thomas.
Now when I run the command I got this output that is shown below. I do not know
why the dhcp test fails; but in spite of that I was able to install two compute
nodes.
xcatprobe xcatmn -V -i eno5

Simulate a node xcatmntest<ip=10.50.1.8 mac=aa:aa:aa:aa:aa:aa> to do
dhcp test
DHCP server reply is wrong
Run 'makedhcp -n' if it has not been ran before.

Subject: Re: [xcat-user] xcat dhcp issue
Hello,
may not be related but I had before no free lease issue when nodes to be
discovered booted before the xCAT node's object was created.
I think then I manually removed the lease from the lease files (which may not
be appropriate because of some race conditions).
