If you have a Hyper-V Cluster connected through iSCSI to a storage solution and sometimes you get errors that your CSV volumes went offline. In some cases, the Windows Failover Cluster is able to recover and bring online automatically and your virtual machines will not stop. In other situation if your CSV volume is not been recovery you will have to bring online the volume and then start all the...
In a failover cluster, virtual machines can use Cluster Shared Volumes that are on the same LUN (disk), while still being able to fail over (or move from node to node) independently of one another. Virtual machines can use a Cluster Shared Volume only when communication between the cluster nodes and the volume is functioning correctly, including network connectivity, access, drivers, and other factors. You probably didn’t notice any issues...
When do you need to see what updates had been installed on your Hyper-V server, you can use this PowerShell cmdlet to list all the updates. Get-WmiObject -Class Win32_QuickFixEngineering | select description,hotfixid,installedon Then if you need to compare if all the nodes of your cluster or if your Hyper-V server have the same patch level just run this cmdlet remotely through PowerShell ISE. If you need help run remotely PowerShell...
On the previous version of Windows Server (prior Windows Server 2012) you have to download and install MultiPath I/O (MPIO). Since Windows Server 2012 MPIO is a feature that you can enable. Because it’s a feature that comes with the server, means that you will have the PowerShell cmdlets available. Use of the MPIO module in Windows PowerShell requires an “elevated” PowerShell window, opened with Administrator privileges. How to do...
Sometimes when you deploy an Hyper-V Server you don’t know if you miss any configuration or if you are following the best practices regarding security, configuration or even supportability of Hyper-V Server in case you need some help from Microsoft Support. To help us Microsoft has created a few rules to help us improve our environments — these are referred to as best practices. However, it is not easy to...
In some medium/large organizations, it is common practice to have different access levels for systems, such as administrator, help desk, support and auditor. When implementing virtual machine using Hyper-V Servers, it is also important to reflect these access levels as well. Since Hyper-V 2012 makes this task easier when you need to specify particular users or groups to be Hyper-V Administrators, but you also might face scenarios where different levels...
As a virtualization administrator, you will come across a lot of scenarios where you will need to create, modify, move, export, and other tasks to manage your virtual machines every day. In some examples, you will need to change a few small and easy settings, which can be done via a graphical interface. However, you will also get cases where lots of virtual machines will need some advanced configuration or...
Working with PowerShell can be very common for daily tasks and Hyper-V Server management. However, as there is more than one server to be managed, sometimes it can be difficult to log on and run the PowerShell scripts (most of the time the same one) on different computers. One of the benefits that PowerShell offers is the remote option that allows you to connect to multiple servers, enabling a single...
Cluster, Hyper-V Replica, Storage Migration, and other features makes for a higher availability for Hyper-V virtual machines, but it is impossible to provide 100 percent assurance in any system. When we lose a host computer, for example, not only is a single system offline, but also all the virtual machines that are running in there. It does not matter if it is only an application, a virtual machine, or the...
Previous versions of Hyper-V (like 2008, 2008 R2 and 2008 R2 SP1) had complications and incompatibilities with the built-in backup tool, forcing the administrators to acquire other solutions for backing up and restoring. Since Windows Server 2012, Windows Server comes with a feature known as Windows Server Backup (WSB), which has full Hyper-V integration, allowing you to back up and restore your server, applications, Hyper-V, and virtual machines. WSB is...
