We are going to be getting some new heads for our cluster. The new heads are going to require that the cluster use a single_image cfmode. We currently are in a partner cfmode. I am wondering if we are going to need to stop all traffic to the filers (nfs, iscsi) when we change the cfmode or can we just stop all the fcp traffic to the filers and do the cfmode changes while the tcp traffic to the filers continues? I seem to find conflicting documentation on this. In the &quot;Changing the Cluster cfmode Setting in Fiber Channel SAN Configurations&quot; pdf they don&#39;t mention anything about having to reboot the heads but in one of the knowledgebase articles talking about having to change the cfmode, they state: &quot;Reboot any system on which this change has been made.&quot;<br>
