Created a new OES2SP1 Linux cluster, but I cannot join the cluster from my Netware 6.5 SP8 server. Should I first create the cluster from Netware and then join with my OES2Sp1 Linux server instead?

When trying to join with my NW-server I got:
Atleast one server in the cluster must be operational to add additional nodes.
(ping is working, servername in hosts-file, dns is fully working).

I know that Novell does not support running mixed, but this is a LAB for my migration later on.... all servers fully patched.

Please advice guys :)
