Figure 26. Virtual disk health status

Operating system recovery

This section provides an overview of the steps involved in operating system recovery on Dell EMC Solutions for Azure Stack HCI.

NOTE: Ensure that the RAID 1 virtual disk created on the BOSS M.2 drives is reinitialized.

NOTE: To help reduce repair times when the node is added back to the same cluster after recovery, do not reinitialize or

clear the data on the disks that were a part of Storage Spaces Direct storage pool.

Manual operating system recovery

For manually deployed nodes, you can recover the operating system on the node by using any of the methods that were used for

operating system deployment.

Factory operating system recovery

For the factory-installed OEM license of the operating system, Dell recommends that you use the operating system recovery media that

shipped with the PowerEdge server. Using this media for operating system recovery ensures that the operating system stays activated

after the recovery. Using any other operating system media triggers the need for activation after operating system deployment. Operating

system deployment using the recovery media is the same as either retail or other operating system media based installation.

After completing the operating system deployment using the recovery media, perform the following steps to bring the node into an

existing Azure Stack HCI cluster:

1. Update OOB drivers.

2. Configure host networking.

3. Change the hostname.

4. Perform AD Domain Join.

5. Configure the QoS policy (for RoCE for RDMA only).

6. Configure RDMA.

7. Configure the firewall.

8. Perform Day 0 operating system updates.

9. Add server nodes to the cluster.
