Automating patching of operating system servers in a Microsoft Hyper-V cluster
You can use Server Automation to automate patching of operating system servers in a Microsoft Hyper-V cluster, without affecting the data availability groups operations. Server Automation enables you to automate the patching process using a number of Tasks which manage the cluster as it is being patched. The Tasks prepare nodes for patching by pausing them and moving all virtual machines, groups, and resources off the nodes. The required patches are then applied to the operating system as part of the automation flow. After the operating system is patched, the automation flow restores the nodes to their original pre-patching state.
Before you begin
- Control scripts must be installed on each of the endpoints that you are patching. Use Server Automation Task 110 Install Windows Cluster Control Application to install the control scripts.
- The Powershell feature must be installed on each node that you are patching. By default this is installed on all instances of Microsoft Server from 2008 Release 2 onwards, except for core installations. For core installations, use the following links to install Powershell:
About this task
- Windows 2012
- Windows 2012 Release 2
- Windows 2008 Release 2 and later
To automate the patching process, you run an automation plan. The automation plan contains a number of steps, each of which represents a stage in patching process. You can create a new automation plan or modify an existing plan, such as an out-of-the-box sample plan by changing some of the steps.
