Operating system recovery
This section provides an overview of steps involved in operating system recovery on the Dell EMC Solutions for Azure Stack
HCI.
NOTE: Ensure that the RAID 1 VD created on the BOSS M.2 drives is reinitialized.
NOTE: Do not reinitialize or clear the data on the disks that were a part of Storage Spaces Direct storage pool. This will
help in reducing repair times when the node is added back to the same cluster after recovery.
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 CPU chipset, network, and storage 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.
For instructions on steps 1 through 7, see the Dell EMC HCI Solutions for Microsoft Windows Server Deployment Guide.
