Windows Server 2016
version 1607 (OS Build 14393.3808)
I have a 4 node Windows Server 2016 S2D cluster and I want to use Windows Admin Center to manage it. However, when I try to connect, it fails saying "Unable to create the "SDDC Management" cluster resource (required). I have fully updated all the nodes using cluster aware updating. Also, I have created the SDDC Management cluster resource using the following command:
Add-ClusterResourceType -Name "SDDC Management" -dll "$env:SystemRoot\Cluster\sddcres.dll" -DisplayName "SDDC Management"
However, when I go into Failover Cluster Administrator it is in a failed state and I can't get it to start. I thought it might be an issue with the firewall, so I disabled the firewall on all nodes and the machine running WAC. It still will not start.
From the cluster log, I can see the following:
00000dbc.00000fc4::2020/08/10-20:26:44.610 WARN [RCM] HandleMonitorReply: ONLINERESOURCE for 'SDDC Management', gen(3) result 5018/1722.
00000dbc.00000fc4::2020/08/10-20:26:44.610 INFO [RCM] Res SDDC Management: OnlinePending -> ProcessingFailure( StateUnknown )
00000dbc.00000fc4::2020/08/10-20:26:44.610 INFO [RCM] TransitionToState(SDDC Management) OnlinePending-->ProcessingFailure.
I have removed the clustered resource and added it again with the same result. Any ideas on what is happening here?
