Guidance on Network Configurations for Azure Stack HCI Cluster
Hello All, I am going to deploy my very first Azure Stack HCI cluster. I need guidance on how to assign the IP addresses to the NICs, what should be IP address scheme, and best practices. Details of network adapters are as follows: 2 NICs of 25 Gbps for compute/Virtualization (VMs) traffic 2 NICs of 25 Gbps for Storage 2 NICs of 1 Gbps for Mgmt Questions: (1) How to assign the IP addresses? since it's my first time with the black screen. (2) How to configure SET for the NICs to be used for virtualization/compute step-by-step? (3) I know that I don't need to configure SET (Switch Embedded Teaming) for the Storage NICs, but what should I do for the Mgmt NICs? Should I configure SET for them OR should 1 NIC be enough for the Mgmt? (4) How to configure SET step-by-step? (5) What is the recommendation for the IP address scheming for all the NICs? Let's say I'm assigning 10.4.8.x to the Mgmt NICs, should I use the same IP address scheme for Storage and Compute NICs as well, or should I assign some different IP schemes like 172.x.x.x (6) There are 2 NICs for Storage and we are not configuring SET for them... So, just to confirm, will I need to assign 2 IP addresses for Storage on each server? (7) How to enable the iWARP RDMA for the Storage NICs? I'm thinking to use iWARP RDMA as I read MSFT engineers recommend/prefer iWARP over RoCE. Please confirm my understanding. (8) For the Mgmt NIC, first I will configure the SET then I will assign the IP address to the SET NIC, just like we used to with the conventional NIC Teaming in Windows Server 2012 R2. Apologies in advance for such basic questions... It's my first time with Azure Stack HCI... Thank you very much!SolvedHasanHasibJul 20, 2023Copper Contributor8.9KViews1like9CommentsAzure Stack HCI / Azure Local with Stretched Cluster support?
Hi, i need to propone an Azure Stack HCI solution in streteched cluster mode. I see that the stretched cluster is available only in 22h2 version.. It's an old version.. When the Stretched cluster mode will be available on Azure stack hci o windows server 2025 for local only deployment? Thanks!SolvedTheMiloNetDec 01, 2024Copper Contributor1.1KViews1like6CommentsAzure Stack HCI Cluster network name changes from "ClusterNetwork1" to "Unused:ClusterNetwork1"
I have configured Azure Stack HCI Stretched Cluster with Network ATC. Strange behaviour i am noticing is with naming of Cluster Network(screenshot 1). e.g. current name is "Cluster Network1", gets changed to "Unused: Cluster Network1". Also Live Migration settings(screenshot 2) keep selecting multiple adaptors by itself even i uncheck all and only keep "LM" on top an checked. Any suggestions or fix to this.LuckylakhanDec 12, 2023Copper Contributor1KViews0likes6CommentsAlert emails for Azure Stack HCI health issues?
How do I set up alert emails, when the HCI cluster generates a health fault - like a volume running low on available space? I am running Hci OS 22H2 and using WAC with the Dell plugin to manage. I mean: If I had nothing else to do all day and night, I could sit and stare at WAC and I am sure that something would pop up. But that is not practical. Emails are practical.ThomasI1May 27, 2023Copper Contributor1.6KViews0likes6CommentsAzure Stack HCI & local DHCP
We're replacing our local vSphere infrastructure with Azure Stack HCI. On the vSphere environment we have a DHCP server running that serves ip addresses to our desktops and laptops. Is it possible to run a DHCP server in a VM on Azure Stack HCI? What are the best practices?WouterCoppensApr 28, 2023Copper Contributor1.7KViews0likes6CommentsNetworkATC Stuck on Validating
After migrating our three-node Azure Stack HCI cluster to intent-based networking with network ATC, the configuration status for some of the intents remains in the "Validating" status. I have two intents: One management and compute. One storage. I'm not sure how to troubleshoot why the configuration status doesn't progress to "Success" status. Fortunately, the cluster is operating normally, but I fear something must be wrong. A cluster validation test doesn't indicate any issues. All nodes are running 10.0.25398 Get-NetIntentStatus | select IntentName, Host, ConfigurationStatus, ProvisioningStatus | ft IntentName Host ConfigurationStatus ProvisioningStatus ---------- ---- ------------------- ------------------ storage dun-s-hci1 Success Completed storage dun-s-hci2 Success Completed storage dun-s-hci3 Success Completed management_compute dun-s-hci1 Validating management_compute dun-s-hci2 Validating management_compute dun-s-hci3 ValidatingMattI2290Sep 20, 2024Copper Contributor561Views0likes5CommentsHCI Stack 23H2 WMI - RPC Server is Unavailable
After updating to Solution 10.2405.2.7 I am unable to manage my cluster through the failover manager and unable to run cluster validations due to the error RPC Server is unavailable. I have restarted the nodes, confirmed firewall rules are allowing WMI and RPC, and confirmed DNS. Azure and WAC are reporting no issues with the cluster, I am worried about applying the next solution in case this WMI issue will cause issues with the updates. Any guidance to resolve this fault would be much appreciatedDanielF1395Aug 28, 2024Copper Contributor1.2KViews2likes5CommentsError No File
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 50JensIAug 14, 2025Copper Contributor104Views0likes4CommentsAzure Stack Memory ECC Validation Failed

Scenario: different VMs using Windows Server Datacenter Azure Edition (core and GUI), Clustered and unclustered VMs OS: Azure Stack HCI 22H2 Result: Attestation is working as expected, locally, Azure Portal and WAC 2203. Problem: Server Manager locally or remotely does no longer show the activation status correctly. slmgr /sconfig / WMIC shows a correct activation on VMs that are also correctly configured with Attestation Reproducible: yes, in all cases Server Manager Get-CimInstance SoftwareLicensingProduct -Filter "Name like 'Windows%'" | where { $_.PartialProductKey } | select Description, LicenseStatus sconfig Test IDMS Invoke-RestMethod -Headers @{"Metadata"="true"} -Method GET -Uri http://169.254.169.254:80/metadata/attested/document?api-version=2018-10-01 Result: ok UI & Settings app no popup for failed activation on GUI based installation no watermark hints that the VM is not activated (restart may be required if you just attestated and activated it) activation shows up correctly in Settings app This has worked few months ago. Anyone else? Would appreciate a fix for the sake of consistency, as this has worked well in the past.DeletedOct 17, 20231.7KViews0likes4Comments
