I'm trying to install NCS on two SLES 11 SP3 servers, but I'm stuck on this.

I can install NCS on the first server, and create the cluster object in eDir. I can see the cluster object in iManager after that.

But when I try to add the second server, I get the error from the title, even selecting the cluster object on the selection window (i.e. not typing its name).

I've searched a lot, and read the documentation, but no progress.

Can anyone help me?
