Hello,
when you say "we disconnected all NIC cables" you mean "we
disconnected all NIC cables but the ones connected to the iLO
interface", correct?
Because to know that one host has successfully fenced the problematic
one, it has to send a get status message and see that it is off or
that it has been successfully rebooted.....

For esxample in RHCS if you configure iLO as a fencing device it
remains indefinitely in state similar to

wait for fence to complete

if the "fencer" is not able to get an acknowledge about the operation
or to reach the other node iLO.
Probably you can find something in your logs...
