<p class="MsoNormal"><span style="font-size:12.0pt">Short answer is that if you want to change/remove the NSD server config on an NSD and its part of a file systems, you need to remove it from the file system or unmount the file system. *<b>Thankfully</b>*
this is changed in Scale 5.0.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">In your case (host name change) – if the IP address of the NSD server stays the same you *<b>may</b>* be OK. Can you put a DNS alias in for the old host name? Well, now that I think about it the old host name
will stick around in the config – so maybe not such a great idea.<o:p></o:p></span></p>
