Linux with Db2 cluster on Azure Stack Limitation
We are using Linux based IAAS compute service with 2 or more Db2 and GPFS nodes setup in Active / Standby mode. Here the cluster fail-over mechanism needs a VIP which I assume is not available on Azure Stack Hub. In the Azure public cloud, the backend cluster uses the automatic script via Azure CLI to update private DNS zone and A record with CNAME to promote the Master / Active node during the fail-over process. Is that correct that the Private DNS zone services unavailable on Azure Stack Hub hence we can't form a cluster like this. I read on the Azure Stack Hub DNS article that we have an internal zone as azurestack.local that's used for infrastructure services in Azure Stack Hub. It's Directory Service-integrated and private (not reachable from outside the Azure Stack Hub deployment). But this recursive server is used to resolve names of everything except for the "internal private zone" and the external public DNS zone for that Azure Stack Hub deployment. What is the workaround or solution to resolve our issue for private DNS zone.
Nested 23H2 cluster deployment stuck in "Resolve requirement"
Hi all, I'm breaking my head over this. Every time I deploy new cluster it's always stuck in Resolve requirement. It was fine before but there is no way now to move from it. Host 1 restarts after 15min of deployment and then all goes quiet and finally cluster deployment fails. Anybody any idea?
Azure Stack HCI Registration Help
We are waiting on arrival on our Azure Stack HCI cluster. In the meantime I have been trying to setup a test environment. The challenge I have is with registering the cluster with Azure. I understand their are specific Azure permissions need for the account that performs the registration. My intention was to register the system on my Visual Studio Subscription. Everything appeared to go ok until what I suspect was my last step. The last step - where I selected my Visual subscription gave me the somewhat expected permission error. Another organization within our college owns the tenant and we'll have to work with them when it comes time to register our production system. Here is where I could sure use some help. Since this permission issue still needs to be hammered out and this is just a test I figured I would try registering it with my personal Azure account. When I try to do that, it errors stating that my personal subscription is not found in the tenant. Which is true.... The problem is I can't figure out how to "unregister the incomplete registration." Everything I see shows the system to be "unregistered." Short of burning my test systems down and restarting, is there anything I can do to reset this registration process? Thanks, Jim
AKS on AzureLocal: KMSv1 -> KMSv2
Hey, quick question on AKS Arc — we're running moc-kms-plugin:0.2.172-official on an Arc-enabled AKS cluster on Azure Local and currently have KMSv1=true as a feature gate to keep encryption at rest working. KMSv1 is deprecated in 1.28+ and we want to migrate to KMSv2 before it gets removed. Since moc-kms-plugin is a Microsoft-managed component we can't just swap it out ourselves. A few questions: Does version 0.2.172 already support the KMSv2 gRPC API, or is that coming in a later release? Is there a supported migration path for AKS Arc specifically, or does this come automatically through a platform update? Any docs or internal guidance you can point us to? Thanks!
RDMA (RoCE) Test Failed over different Subnet
Hello Everyone, Let's say pSMBNIC1 and pSMBNIC2 are the names of the NICs to be used for RDMA on each node of a 3-node cluster. IP address assignments are as follows: pSMBNIC1 = 192.168.207.31 (N1), 192.168.207.32 (N2), 192.168.207.33 (N3) pSMBNIC2 = 192.168.206.51 (N1), 192.168.206.52 (N2), 192.168.206.53 (N3) RDMA Test is Successful when I run for the following scenarios: From pSMBNIC1 of N1 to pSMBNIC1 of N2 (192.168.207.32) and pSMBNIC1 of N3 (192.168.207.33) From pSMBNIC1 of N2 to pSMBNIC1 of N1 (192.168.207.31) and pSMBNIC1 of N3 (192.168.207.33) From pSMBNIC1 of N3 to pSMBNIC1 of N1 (192.168.207.31) and pSMBNIC1 of N2 (192.168.207.32) From pSMBNIC2 of N1 to pSMBNIC2 of N2 (192.168.206.52) and pSMBNIC2 of N3 (192.168.206.53) From pSMBNIC2 of N2 to pSMBNIC2 of N1 (192.168.206.51) and pSMBNIC2 of N3 (192.168.206.53) From pSMBNIC2 of N3 to pSMBNIC2 of N1 (192.168.206.51) and pSMBNIC2 of N2 (192.168.206.52) However, RDMA Test fails with "ERROR: RDMA traffic test FAILED: Please check ERROR: a) physical switch port configuration for Priority Flow Control. ERROR: b) job owner has write permission at 192.168.206.51 \C$" for the following scenarios: From pSMBNIC1 of N1 to pSMBNIC2 of N2 (192.168.206.52) and pSMBNIC2 of N3 (192.168.206.53) From pSMBNIC1 of N2 to pSMBNIC2 of N1 (192.168.206.51) and pSMBNIC2 of N3 (192.168.206.53) From pSMBNIC1 of N3 to pSMBNIC2 of N1 (192.168.206.51) and pSMBNIC2 of N2 (192.168.206.52) From pSMBNIC2 of N1 to pSMBNIC1 of N2 (192.168.207.32) and pSMBNIC1 of N3 (192.168.207.33) From pSMBNIC2 of N2 to pSMBNIC1 of N1 (192.168.207.31) and pSMBNIC1 of N3 (192.168.207.33) From pSMBNIC2 of N3 to pSMBNIC1 of N1 (192.168.207.31) and pSMBNIC1 of N2 (192.168.207.32) This means that RDMA Tests are passing for the same subnets but failing when run across different subnets. Is it normal? I have already enabled the PFC... But, even if the PFC is not enabled, then how tests are passing for the same subnet? Please guide...

Issue with Hyper-V VM on Tagged VLAN – Traffic Reaches Local Hosts but Not External Networks
Hi everyone, I’m having an issue getting a Hyper-V VM to work correctly when using a tagged VLAN interface. I have a test VM configured with a trunk port and a tagged VLAN. Here is the configuration I’m using: Set-VMNetworkAdapterVlan -VMName "testvlan" -Trunk -NativeVlanId 2 -AllowedVlanIdList "4" The strange part is this: When the VM is on VLAN 4 (tagged), it can reach other resources on the same VLAN as long as those resources are running on the same Hyper-V host. But if the target resource is outside the Hyper-V host, the VM cannot reach it at all. The hardware vendor has already ruled out any issue with the top-of-rack switches interconnecting the hosts. If I reconfigure the VM’s network adapter in access mode on the same VLAN, then all traffic works normally and the VM can reach resources outside the host without any problem. So it seems that traffic leaves the host correctly only when the adapter is in access mode, not when using a trunk with VLAN tagging. Has anyone seen this behavior before or has suggestions on what to check next?
Azure Local
i am trying to install Azure local on nested Hyper-V VM as test environment, 1 DC, 1 HCI VM and unfortunately i am stuck with an error: "Type 'ValidateArcIntegration' of Role 'EnvironmentValidator' raised an exception: { "ExceptionType": "text", "ErrorMessage": "The provided account MSI@50342 does not have access to subscription ID \"7187cfd2-689c-4918-b43b-6e767d2bc1eb\".

I have tried to deploy the Azure Local cluster based on Stack HCI, but are currently stuck on the Creating Cluster portion. However the fault it gives is very unclear and says there is a network configuration error however All previous steps where succesfull including setting up networking where I assume it would have failed if it was a networking issue. The name of the cluster would be something else if I where to configure it manually but this name comes from Azure and was validated there. Error: Type 'ConfigCluster' of Role 'Cluster' raised an exception: Check the spelling of the cluster name. Otherwise, there might be a problem with your network. Make sure the cluster nodes are turned on and connected to the network or contact your network administrator. at SetClusterLiveDumpPolicy, C:\NugetStore\Microsoft.AzureStack.Fabric.Storage.SCPSModule.10.2507.1001.1000\content\CloudDeployment\Classes\Cluster\Cluster.psm1: line 898 at ConfigCluster, C:\NugetStore\Microsoft.AzureStack.Fabric.Storage.SCPSModule.10.2507.1001.1000\content\CloudDeployment\Classes\Cluster\Cluster.psm1: line 322 at <ScriptBlock>, C:\CloudDeployment\ECEngine\InvokeInterfaceInternal.psm1: line 163 at Invoke-EceInterfaceInternal, C:\CloudDeployment\ECEngine\InvokeInterfaceInternal.psm1: line 158 at <ScriptBlock>, <No file>: line 50
