    P2V using Hyper-V 2012

    Here is how I started doing P2V on a Hyper-V 2012. I have SCVMM 2012. I want to do a V2V from a Citrix XenServer VM to a Hyper-V VM. The way to go about it is to do a P2V. The official technet documentation says run System Center Virtual Machine Manager Configuration Analyzer (VMMCA) first. Installing and running SC VMMCA So I installed System Center Virtual Machine Manager Configuration Analyzer on my Windows 7 workstation. It needed a couple of prerequisites like MBCA 2.0.

    Presenting LUNs to Hyper-V 2012

    Here are my notes on presenting a LUN from a 3PAR 7400 SAN to a Hyper-V 2012 server running no GUI. The SAN is connected to the server via Fiber. There is a FC switch in between which has been properly configure, zoned, etc. Multiple paths to the same LUNs are configured for redundancy and speed so we need MPIO. Procedure: 1. Install MPIO feature and reboot the Hyper-V server Note that I did not run the mpiocpl GUI or the mpclaim command as I described here earlier. You may have to do that. 2. From  inside the SAN management console, present a LUN to the Hyper-V server. Note: while…

    Enabling MPIO in Windows Server 2012 core

    Here is how you can enable MPIO quickly in a Windows server 2012 core  installation like Hyper-V 2012 (without GUI).

After the reboot you can either use the command mpclaim to enable MPIO for unclaimed devices [meaning those LUNs which appear like 4 separate disk drives but are actually one LUN connected via 4 paths]: mpclaim –r –i –a Note: I am getting an error saying that an invalid switch was specified. However I ran this command BEFORE rebooting the Hyper-V server. YMMV.…

    Hyper-V Server 2012 quick start guide

    Here is how I got started with Hyper-V Server 2012 First, let  me be clear which version of Hyper-V am I talking about. This is the Hyper-V standalone version, or the free version as some people call it. Basically it is a separate download from MSDN and runs a pre-configured server core version + hyper-V role already installed.
