&gt;Hello,
&gt;
&gt;It&nbsp;is&nbsp;most&nbsp;commonly&nbsp;caused&nbsp;by&nbsp;having&nbsp;a&nbsp;network&nbsp;defined&nbsp;as&nbsp;"required"&nbsp;in
&gt;a&nbsp;cluster,&nbsp;and&nbsp;not&nbsp;having&nbsp;it&nbsp;set&nbsp;up&nbsp;on&nbsp;a&nbsp;host&nbsp;in&nbsp;that&nbsp;cluster.&nbsp;It&nbsp;is
&gt;usually&nbsp;accompanied&nbsp;by&nbsp;a&nbsp;human-readable&nbsp;explanation&nbsp;in&nbsp;the&nbsp;events&nbsp;panel
&gt;at&nbsp;the&nbsp;bottom&nbsp;of&nbsp;the&nbsp;webadmin&nbsp;GUI.
&gt;
&gt;If&nbsp;that&nbsp;is&nbsp;indeed&nbsp;the&nbsp;problem,&nbsp;it&nbsp;can&nbsp;be&nbsp;fixed&nbsp;in&nbsp;one&nbsp;of&nbsp;two&nbsp;ways,
&gt;depending&nbsp;on&nbsp;whether&nbsp;the&nbsp;network&nbsp;is&nbsp;actually&nbsp;essential&nbsp;for&nbsp;your&nbsp;cluster:
&gt;
&gt;1.&nbsp;If&nbsp;it&nbsp;is&nbsp;essential,&nbsp;choose&nbsp;the&nbsp;non-operational&nbsp;host,&nbsp;navigate&nbsp;to&nbsp;the
&gt;"Network&nbsp;Interfaces"&nbsp;subtab,&nbsp;click&nbsp;"Setup&nbsp;Host&nbsp;Networks"&nbsp;and&nbsp;make&nbsp;sure
&gt;that&nbsp;the&nbsp;required&nbsp;network&nbsp;is&nbsp;attached&nbsp;to&nbsp;a&nbsp;network&nbsp;interface&nbsp;on&nbsp;the&nbsp;host.
&gt;
&gt;2.&nbsp;If&nbsp;it&nbsp;is&nbsp;not&nbsp;essential,&nbsp;choose&nbsp;the&nbsp;corresponding&nbsp;cluster,&nbsp;head&nbsp;to&nbsp;its
&gt;"Logical&nbsp;Networks"&nbsp;subtab,&nbsp;click&nbsp;on&nbsp;"Assign/Unassign&nbsp;Networks"&nbsp;and&nbsp;mark
&gt;the&nbsp;network&nbsp;as&nbsp;non-required.
&gt;
&gt;Yours,&nbsp;Lior&nbsp;Vernia.
