Ok, the "-V" flag did not do what I expected.
Edit file /opt/xcat/probe/subcmds/xcatmn and around line 19, flip "my
$verbose = 0;" from 0 to 1. Then rerun "xcatprobe xcatmn -i eno5"
without the "-V" flag.

SOPORTE,
Is this problem related to "xCAT 2.16.2 new xNBA issue" thread.
If not, can you start a new thread ?
Try to rerun the xcatprobe with verbose flag:
xcatprobe -V xcatmn -i eno5
