Issue Cloud Service IP CIDR is required when setting up resource bridge for Azure Stack HCI

So i was setting up a Azure Stack HCI Lab today and came across a error msg when running the set-mocconfig command.

My cluster has static IP addresses on everything and for some reason it then requires the Cloud Service IP CIDR to be set static. And you can’t use a parameter like $cloudservicecidr = “IP Address” You need to specify it in the line.

Error msg i got was

Cloud Service IP CIDR is required when using static IP assignment.

It works if adding -cloudServiceCidr at the end after stable.

#On Mode
Set-MocConfig -workingDir "\\$using:ClusterName\ClusterStorage$\$using:VolumeName\workingDir" -vnet $vnet -imageDir $using:VolumePath\imageStore -skipHostLimitChecks -cloudConfigLocation $using:VolumePath\cloudStore -catalog aks-hci-stable-catalogs-ext -ring stable -cloudServiceCidr

Cluster Node failed to join the cluster

Hey everyone, another Failover Cluster issue i came across lately. And i wanted to share this one as i could not find any good resources online for this issue. So here we go.

Manually adding a patch to WSUS

So this week there was a new Cumulative Update out that i wanted to test on a Storage Spaces Direct cluster. But as im using WSUS and VMM to patch my clusters i needed that patch to be in WSUS and it’s not. It will still take a few days before that patch get’s synced to WSUS, and i did not want to manualy update my nodes.

I googled and found a few posts about this but none that was good enough and it took me a while to find something relevant. So i decided i should share with you how you manually ad a Windows Update KB to WSUS.
