open (PRM, "-|", $NE_obj->cmd("ssh $activepilotrcs reboot ; tailer PRM

Where in the documentation of Control::CLI did you find that usage?

To me it seems that ->cmd returns a string of the command output, not a filehandle to be read from. That's also what the documentation says:

 Sends a CLI command to host and returns output data

Maybe consider checking whether your open call succeeds at all:

open (PRM, "-|", $NE_obj->cmd("ssh $activepilotrcs reboot ; tailer PRM
+"))
    or die "Couldn't open filehandle : $!";

But if you're using ssh anyway, why not run the commands directly through it?

my $output = `(ssh $activepilotrcs reboot ; tailer PRM) |`;

Or, instead, use Net::SSH::Any and use that to send the SSH commands yourself.
