4 Executive summary Executive summary The Dell EMC XC Series family of hyper-converged appliances integrate our proven PowerEdge x86 server platform and Nutanix software into purpose built enterprise-class solutions for virtualized environments. Backed by Dell EMC s Global Service and Support organization, these 1U and 2U appliances consolidate storage, compute, networking, and virtualization into a turnkey platform enabling application and virtualization teams to quickly and simply deploy new workloads. The XC Series, with pay-as-you-grow flexibility, is easily expanded one node at a time for predictable scale-out expansion. By combining the hardware resources from each server appliance into a shared-everything model for simplified operations, improved agility, and greater flexibility, Dell EMC and Nutanix together deliver simple, cost-effective solutions for enterprise workloads. Upgrading Microsoft Windows Server versions on the same hardware is a monotonous process and in past considered highly unadvisable. In previous versions of Windows, it was necessary to build a new Hyper-V server and migrate roles to the newly built server using live migration feature that was introduced in Windows Server 2012 R2. The biggest operational challenge in an appliance that includes various technologies from different providers is maintenance, regardless if it was a firmware, software, or hypervisor upgrade. Dell EMC XC Series Hyper-Converged Appliance solves the reluctance to upgrade by enabling the 1-Click Upgrade feature in the Nutanix Prism Web console. The 1-Click Upgrade process is a non-disruptive workflow that follows a rolling upgrade methodology through the cluster on a node-by-node basis. The intent of this document is to provide detailed step-by-step instructions to successfully upgrade Dell EMC XC Series Hyper-Converged Appliance running Microsoft Windows Server 2012 R2 Hyper-V to Microsoft Windows Server 2016 Hyper-V without compromising the availability of the workload to end users. 4 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

7 Product/technology overview 2 Product/technology overview 2.1 Dell EMC XC Series Hyper-Converged Appliance architectural overview Dell EMC XC Series Hyper-Converged Appliances come with the proven Dell EMC PowerEdge server platform and incorporate many of the advanced software technologies that power leading web-scale and cloud infrastructures. Dell EMC XC Series Hyper-Converged Appliance is a scalable cluster of high performance appliances, each running a standard hypervisor combining processors, memory, local storage consisting of solid state drives (SSD) for performance and high capacity hard disk drives (HDD) in hybrid mode or all flash. Each appliance hosts the virtual machines just like a standard hypervisor as shown below. Standard hypervisor. Dell EMC XC Series Hyper-Converged Appliances use DSF to share and present local storage to server nodes within a cluster while creating a clustered volume namespace accessible to all nodes. Figure 2 shows an overview of the Dell EMC XC Series architecture including user VMs, the Nutanix storage CVM, and its local disk devices. Each CVM connects directly to the local storage controller and its associated disks. Using local storage controllers on each host localizes access to data through the DSF, thereby reducing storage I/O latency. The DSF replicates writes synchronously to at least one other XC Series node in the system by default, distributing data throughout the cluster for resiliency and availability. Replication factor 2 (RF2) creates two identical data copies in the cluster, and replication factor 3 (RF3) creates three identical data copies. 7 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

8 Product/technology overview Dell EMC XC Series architecture DSF virtualizes local storage from all appliances into a unified pool. DSF uses local SSDs and capacity disks from all appliances to store virtual machine data. Virtual machines running on the cluster write data to DSF as if they were writing to local storage. Nutanix data locality ensures that the XC Series node providing CPU and memory to a VM also provides its disk as well, thus minimizing IO that must cross the network. XC Series supports multiple hypervisors and provides choice and flexibility to customer. 2.2 Microsoft Windows Server 2016 Hyper-V on XC Series The Dell EMC XC Series Hyper-Converged Appliance running Windows Server 2016 Hyper-V enables you to leverage on the improvements and new features that have been introduced with Windows Server XC Series brings the HCI appliance benefits of flexibility, affordability, ease of scale, and a fully modern architecture including cloud to Microsoft environments with flexible hardware options and simple management.

10 Hyper-V upgrade 3 Hyper-V upgrade 3.1 Upgrade overview The Dell EMC XC Series Hyper-Converged Appliance solves the reluctance to upgrade by enabling the 1- Click Upgrade feature in the Nutanix Prism Web console. The 1-Click Upgrade process is a non-disruptive workflow that follows a rolling upgrade methodology through the cluster on a node-by-node basis. Before performing an upgrade, a series of pre-upgrade health checks are performed on the cluster that it must pass before proceeding. Once the 1-Click Upgrade process is finished on all the nodes, the final health check is run before finalizing the process. The 1-Click Upgrade process takes care of all the operational activities automatically that are required to perform an upgrade. Before starting an upgrade process on a node, the system ensures that the VMs running on that node are automatically moved to other nodes in the cluster. After the VMs are moved, the node is evicted from the cluster. As soon as the operating system upgrade is completed, the node is added back to the cluster. The Prism 1-Click Upgrade option is available for upgrading AOS (that includes Prism, Distributed Storage Fabric (DSF)), NCC, and Foundation. These upgrades are available from a single location within the Prism interface. 3.2 Best practices This section of the document outlines the best practices to follow to successfully upgrade the Dell EMC XC Series Hyper-Converged Appliance within a Hyper-V cluster to Microsoft Windows Server Dell EMC recommends you follow the best practices defined here to successfully upgrade to Microsoft Windows Server 2016 Hyper-V. Run all cluster health checks, against the entire cluster, from Prism or using command line and ensure there are no issues reported. If there are reported health issues, ensure that the issues are fixed before initiating the upgrade process. Refer to for details on how to collect the cluster health check logs. Update the host OS with all the latest security updates / cumulative updates. Verify the workload (VMs) and workload applications that you are running on this cluster are compatible with Microsoft Windows Server For details refer to Some features that are available in Windows Server 2012 R2 are deprecated in Windows Server Review the features that are being deprecated to ensure that there are no dependencies on these features. For detailed list of deprecated features refer to Back up all your workloads (VMs) before initiating the upgrade process and ensure the backup is completed successfully and can be restored in case of any failure or disaster. Ensure that live migration is working properly between the nodes of the cluster. If there are any VMs that are deployed in customized fashion and may not support live migration, ensure that you planned for the downtime of those VMs and applications while performing the upgrade. 10 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

Click Yes again to initiate the upgrade process. 38 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

39 14. The upgrade process first runs the pre-upgrade check before the actual upgrade process is initiated. 15. Below is the picture of all VMs running on their respective nodes before the upgrade. 16. During the upgrade process, the workload running on a particular node is live migrated to other nodes in the cluster. As shown below, Node1 (809HXK2), which was running VM1 and VM2, is now removed and the VMs are migrating to other nodes in the cluster. 39 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

40 17. As the upgrade process progresses, Node1 (809HXK2) is added back to the cluster, and the workload on Node2 (88BBXK2) is redistributed across the other nodes, and then Node2 is removed. 40 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

41 18. At this stage, the cluster is now running in mix mode where you can have both Windows Server 2012 R2 and Windows Server 2016 nodes in the same cluster. 19. You can monitor the progress of the entire cluster upgrade process from the Prism Web Console tasks list. 20. When all nodes of the cluster are upgraded to Windows Server 2016, you should see the upgrade software dialog box displaying 100% completed. 21. Close the Upgrade Software dialog box and move to the validation steps Validate the upgrade has completed on all the nodes 1. Log in to the Prism Web Console from any node in the cluster or with the cluster IP. 2. On the Home page, in top left corner of the screen, the Hypervisor summary displays the hypervisor version presently running on the cluster. 41 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

42 3. Log in to the idrac console of each node and verify the system information should display the current version of operating system running on the server. 4. Log in to each cluster node, and from Server Manager select Local Server and verify the operating system version of the server. 42 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

43 5. Open the Failover Cluster Management console on one of the cluster nodes and verify all the VMs are up and running. 6. Check that the VMs are distributed among all the nodes of the cluster. You may see the node that was upgraded last may not be hosting any VMs as the upgrade process does not redistribute the VMs. 7. You may live migrate the VMs to redistribute them evenly across all nodes Complete upgrade process At this point, all the nodes have upgraded to Windows Server 2016, but your cluster is still running in Mixed Mode. You can check the current cluster functional level by running the following command in Windows PowerShell on one of the nodes of the cluster. Get-Cluster Select ClusterFunctionalLevel The result of the command at this point would be 8 because the cluster is still running in Mixed Mode and the entire process can be reversed. You can still add a node using Windows Server 2012 R2 into this cluster. When you are sure that you do not have any dependency on Windows Server 2012 R2, and there is no way that you would want to add another Windows Server 2012 R2 node into this cluster, run the following command to update the cluster functional level to Get-Cluster Update-ClusterFunctionalLevel Check the cluster functional level once again by running the first command in this section again. Get-cluster Select ClusterFunctionalLevel Cluster functional level 9 indicates the cluster is running in Windows Server 2016 mode.

A.3 Known issue After upgrading to the latest network firmware, you may experience an issue with a CVM not communicating with other nodes in the cluster, or other CVMs hosted on other nodes in the cluster. This issue happens due to VMQ getting disabled on the NICs that are processing ingress and egress traffic on the node. 49 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance

50 Appendix A.3.1 Symptoms The VMs on the host can ping the host IP but cannot ping beyond the host. If your VM is configured to get the IP configuration from DHCP and the DHCP server resides outside the host, your VM may end up getting an APIPA configuration with X.X. To fix the issue: 1. Download VMQ Autoconfig PowerShell script from Microsoft. Download the script here. 2. Copy the script to the host where you have the issue. 3. In an elevated PowerShell window, set the Execution Policy to Unrestricted. 4. Run the script. The script displays all the NIC cards on the host. 5. Select the NIC card number that is active and is configured with VMs. In the screen below, NIC1 2 is the active NIC. Type the number associated with that NIC, which in this case is 1. Then type 0 when you have finished selecting your NIC, and press Enter. 6. The script retrieves the list of all the processors and associates the processors to the NICs that you select. 7. Verify if the connectivity should be resumed after the VMQ Autoconfig Script completes successfully. 50 Microsoft Windows Server 2016 Upgrade on DELL EMC XC Series Hyper-Converged Appliance
