Post installation tasks for a preview version of Azure Stack HCI

Applies to: Azure Stack HCI preview channel

This article details how to update the cluster functional level and storage pool after joining the preview channel and installing the Azure Stack HCI OS.

Post installation steps

Once the feature updates are installed, you'll need to update the cluster functional level, and the storage pool version using PowerShell in order to enable new features.

  1. Update the cluster functional level.

    We recommend updating the cluster functional level as soon as possible. If you installed the feature updates with Windows Admin Center and checked the optional Update the cluster functional level to enable new features checkbox, you can skip this step.

    Run the following cmdlet on any server in the cluster:

    Update-ClusterFunctionalLevel

    You'll see a warning that you can't undo this operation. Confirm Y that you want to continue.

    Warning

    After you update the cluster functional level, you can't roll back to the previous operating system version.

  2. Update the storage pool.

    After the cluster functional level has been updated, use the following cmdlet to update the storage pool. Run Get-StoragePool to find the FriendlyName for the storage pool representing your cluster. In this example, the FriendlyName is S2D on hci-cluster1:

    Update-StoragePool -FriendlyName "S2D on hci-cluster1"

    You'll be asked to confirm the action. At this point, new cmdlets will be fully operational on any server in the cluster.

  3. Upgrade VM configuration levels (optional).

    You can optionally upgrade VM configuration levels by stopping each VM using the Update-VMVersion cmdlet and then starting the VMs again.

  4. Verify that the upgraded cluster functions as expected.

    Roles should fail-over correctly and if VM live migration is used on the cluster, VMs should live migrate successfully.

  5. Validate the cluster.

    Run the Test-Cluster cmdlet on one of the servers in the cluster and examine the cluster validation report.
