Hi,
I have an Azure Local infrastructure. I plan to create a Kubernetes cluster with Azure Arc.
I want to manually select a storage path when I create an ARC-enabled,
For example, I have the storage paths below, like in the photo
By default, when you create a Kubernetes cluster with Azure Arc, it selects automatically one or more of the given storage paths.
I want to manually select the storage path in which will reside all the VMs of the control plane and node pool. Also, all the VMs that are created by the cluster autoscaler when it will increase or decrease the number of VMs depending on the load.
This is regarding Azure StackHCI 24h2
Thank You

Hi Elvi Veruari,
As per my understanding, you can manually select the storage path for all control plane and node pool VMs-including those created by the autoscaler-when deploying an AKS (Azure Kubernetes Service) cluster enabled by Azure Arc on Azure Stack HCI 24H2.
By default, when you create an AKS Arc-enabled cluster, the system automatically selects a Cluster Shared Volume (CSV) storage path for the VMs if you do not specify one. This default storage class uses CSV to create VHDX-backed volumes for persistent storage.
for more reference: https://learn.microsoft.com/en-us/azure/aks/aksarc/kubernetes-walkthrough-powershell
During cluster creation (using PowerShell, Windows Admin Center, or automation tools), you can specify the exact storage path (CSV) you want to use for all cluster VMs. This includes the control plane, node pool, and any additional VMs created by the autoscaler as your cluster scales up or down. https://www.supermicro.com/solutions/azure-stack-hci/2023-12/AKS-HCI.pdf
Hope it helps!

Hello Mounika Reddy Anumandla,
I have tried those links and many more, but I am still not able to create them. Those URLs are more for older versions like 22H2, not for 23H2 or 24H2.
So the main question here is: Could it be done in 23H2 or 24H2? Besides https://learn.microsoft.com/en-us/azure/aks/aksarc/kubernetes-walkthrough-powershell we did not have other official documentation.
Please let me know if you have more info that you can share. Thank you in advance.
BR,
Elvi

Hello @Bheemani Anji Babu thank you for the information
I really appreciate your feedback. It’s valuable to us. Please click Accept Answer on this post to assist other community members facing similar issues in finding the correct solution.
Right now, if you are creating an Arc-enabled AKS cluster on Azure Stack HCI version 23H2 or 24H2, you cannot choose your own storage path. The system automatically uses a default path, usually under ClusterStorage and doesn’t let you change it during setup.
However, if you are using 21H2 or 22H2 versions you can choose the custom storage path using PowerShell.
Microsoft may add this feature in newer versions later. To stay updated check the official documentation here: <https://learn.microsoft.com/en-us/azure/azure-local/?view=azloc-2504>
I hope this has been helpful!
