Extending a Cluster Shared Volumes (CSV)
First: Extend LUN using OEM-specific tools
The first step isn’t one that I can document specifically because it is OEM-specific for the toolset. As you know, SAN’s are a form of Shared I/O and due to this they are managed using a set of proprietary tools (usually) and as such I can’t really provide guidance because of this. However, to summarize a bit what you should do is similar to the following steps as I
Hyper-V Replica Configurations
Hyper-V Replica is a built-in functionality added into Hyper-V role which uses asynchronous data replication technology to replicate Hyper-V virtual machines in a primary site to the Disaster recovery (DR) site using a single network connection. DR is a very important component for every IT system and it is very important to have some sort of backup/recovery option in case of a disaster, which involves datacenters, servers, storage, network bandwidth etc. The Hyper-V Replica components consist
Step-by-Step: Setup and Configure Azure Site Recovery (ASR) for On-Premises Hyper-V Host
Here is a step by step walk-through on how to go about setting up and configuring ASR (Azure Site Recovery) and backing up your On-Premises Virtual Machines (VMs) with Azure Resource Manager (ARM). First things, first, Azure’s Recovery Service Vault is a unified vault/resource that allows you to manage your backup and data disaster recovery needs within Azure. For example, if you are hosting your VMs on-premises you can create a link between your on-prem site and Azure to allow your VMs to
Configure NAP RADIUS to serve Cisco WLAN Controllers
- Add the Wireless LAN Controller as an authentication, authorization, and accounting (AAA) client on the NPS.
- Expand RADIUS Clients and Servers. Right-click RADIUS Clients, and choose New RADIUS Client.
- Enter a Friendly name (WLC in this example), the management IP address of the WLC (192.168.162.248 in this example) and a shared secret. The same shared secret is used to configure the WLC.

Repair a Windows Image using DISM
Using DISM with the ScanHealth option
Use the DISM command with the /ScanHealth switch to scan the Windows image for any corruption. Unlike the /CheckHealth, the /ScanHealth switch can take up to 10 minutes to complete the process. To run the command do the following:
- Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin).
- Type the following command and press Enter:
DISM /Online /Cleanup-Image
VMM Resource Reporting
It can be difficult to monitor and assess resources in large Hyper-V environments. This Powershell based script helps you to understand virtualization inventory, capacity and general resource availability in your Standalone or Clustered Hyper-V Environment.
- Creates a plain but detailed and user-friendly HTML report which is compatible with all modern browsers.
- Has an Overview section which shows momentary cluster resource
Extending a Volume Cluster Shared Volumes (CSV)
There are often times where you have a need to expand a LUN when running enterprise systems. This is a trivial action in most cases because you simply add physical drives to the array and then use Disk Management to extend the drive to encompass the newly expanded volume. Unfortunately, on highly-available systems such as those running Failover Clustering with Cluster Shared Volumes (CSV)-enabled features the drive is reserved and un-manageable by Disk Management. However,
Deploy Microsoft Web Application Proxy
Microsoft Web Application Proxy [WAP] is a new service added in Windows Server 2012 R2 that allows you to access web applications from outside your network. WAP functions as a reverse proxy and an Active Directory Federation Services [AD FS] proxy to pre-authenticate user access.
