- Annual feature update for an Azure Stack HCI Solution
  Azure Stack HCI is a hyperconverged infrastructure (HCI) operating system that is delivered as an Azure service. HCI provides the latest security, performance, and feature updates at regular intervals. Updates are provided in the form of monthly quality updates and annual feature updates. The annual feature update is a major update and requires adequate resources and planning. Dell Engineering has worked with Microsoft on listing together prerequisites that should be considered and met before you update your Azure Stack HCI Solution, and also listed the different supported methods of updating your solution. We recommend that you go through this section before you decide which method to choose for updating your infrastructure.
- Firmware and driver updates using the manual method
  These procedures describe how to prepare and update firmware and drivers on an Azure Stack HCI cluster manually.
- Restarting a cluster node or taking a cluster node offline
- Expanding the Azure Stack HCI cluster
- Extending volumes
- Performing AX node recovery
  If a cluster node fails, perform node operating system recovery in a systematic manner to ensure that the node is brought up with the configuration that is consistent with other cluster nodes.
