It is caused by this line of code in /opt/xcat/sbin/xcatd:
#ok, if nodes have numbers, this sorts them numerically... roughly..
#if node doesn't, then it spews a message, need to fix
my @nodes = sort {($a =~ /(\d+)/)[0] <=> ($b =~ /(\d+)/)[0] || $a cmp $b
} (keys %{$handler_hash{$_}});
It is just a warning message that node names does not contain numbers. If
it contains the numbers, it will sort the nodes with the numbers,
otherwise the nodes will still be sorted alphabetically. It should not
affect other functions.
If you do not want to see the warning sign, please comment out "use
warnings;" line at the beginning of /opt/xcat/sbin/xcatd file.
We'll try to fix it in xCAT 2.8.

Subject: [xcat-user] xcatd process starts with warnnings on service
nodes
We get the following message when trying to start xcatd on service nodes -
Use of uninitialized value in numeric comparison (<=>) at
/opt/xcat/sbin/xcatd line 1225.
Looks like at the end xcat starts ok (not completley sure) but it take a
lot of time. we did not had those issues before.
thx.
