026 - Was tun bei "ANS4219E NODENAME cannot be the same as HostName"?

This message appears if you have an entry of the type "nodename xyz" in the "dsm.opt" file, where "xyz" is the host name. If the node name is the same as the host name, such an entry in "dsm.opt" is not only not necessary, it also leads to the above error message and must therefore be removed.
