Veeam: re-map MoRef ID of protected VMs when replacing the vCenter Server

“Object with reference <vmname> was not found in the hierarchy cache.” Have you ever met such an error message during replacing the vCenter Server configured in Veeam Backup & Replication? Or maybe in the case of an inventory change in the vCenter? A similar message pops up when a Virtual Machine’s MoRef changes. To complete backup jobs successfully, you need to re-map the MoRef ID of protected VMs, namely to keep same MoRef IDs for all protected virtual machines. How should that be done?

VMware Horizon View 7.x. configuration backup & recovery

VMware Horizon View is a VMware product that aims to improve the infrastructure of the virtual desktop as well as support bring your own device (BYOD) programs. Most administrators back up virtual desktops, but very few pay enough attention to backing up the Horizon View configurations. At the same time, a backup of a VMware Horizon View environment configuration is a critical part of the work of your virtual desktop infrastructure that guarantees its integrity. Moreover, if you any have problems with a large View Manager configuration that can last from several hours to several days, your Horizon View configurations need a safe harbor badly. So, don’t wait for a second!

5 Tips to Master VMware vCenter Server Appliance

VMware vCenter server appliance is evolving with every major release of VMware vSphere Suite. The product, which manages the whole vSphere infrastructure, can be either installed on a Windows server or deployed as pre-configured virtual appliance called vCenter Server Appliance (VCSA). Over several VCSA releases, VMware managed to make this product equal to the Windows-based one, and it pushes the development even further so now the Linux based product has more features than the vCenter server installed on Windows. However, many VMware admins are also Microsoft guys and like the graphical user interface to work with. That’s why today we’ll have a look at 5 Tips to manage this appliance. We won’t go into the configuration steps within this post as this has been documented many times.

vSphere Upgrade Options

When it comes time for your vSphere upgrade there are many different approaches to how you perform the upgrades on your ESXi hosts.   An administrator who looks after a small cluster may update one way, whereas an administrator who looks after an enterprise with 1000s of hosts may opt to go another.  Also, depending on how your environment is deployed you might want to choose one method over another.  Factors such as a whether or not your hosts are managed by a vCenter server, whether or not they are members of a cluster – these things all impact the methods in which you chose to update to the latest version of ESXi.  Certainly, some methods are much more simplistic than others to perform, some offer more advantages when upgrading at scale, and some are more prone to user error – let’s take a look at each method of upgrading our hosts below and discuss the benefits and drawbacks of each…

Setting statistics collection levels for the VMware vCenter Server and estimating the size of its database

Very often, VMware vSphere administrators have to find the reasons of performance issues by analyzing the historical data of various metrics on the VMware vCenter Server. However, sometimes the default set of metrics is not enough if you view performance data for the previous night or the end of the past week – in this case, you need to change the level of collected metrics and, possibly, the frequency of their collection and retention. In the VMware vCenter Server settings, you can set the data collection levels, different collection intervals and the time period that the data will be stored on the Server. In addition, you can set an approximate size of the virtual infrastructure in the host servers and virtual machines, which will allow to roughly estimate the size of the vCenter database. Let’s take a closer look at these settings.

vSphere 6.5: HA & DRS improvements. Part I

A number of improvements that have been introduced in vSphere HA and DRS in the last several years are impressive. vSphere 6.5 continues this tradition by bringing new features into HA Admission Control, by adding flexibility with HA Orchestrated Restart and by enabling DRS to make more intelligent balancing. I will be trying a new format today. First, I will be explaining the challenges you might have had in previous vSphere releases and then I will show you how the new vSphere 6.5 HA & DRS features address those challenges.
