Disaster: Sector “0” Blanked for Cluster CSV, VMM Incomplete Configuration

Earlier this week, I had the privilege of living through a living hell whereby I was wondering what exactly would happen when our development engineering team had to figure out how to rebuild 53+ virtual machines hosted on a Failover Cluster with Clustered Shared Volumes (CSV) enabled.  The first question is why don’t you have…

Provisioning your Private Cloud in VMM 2012–Getting Started 101

In our group, we have several highly-available sets of clusters that service various needs.  We have one cluster dedicated to running our Team Foundation Services (TFS) and all the System Center management infrastructure to support all clusters.  These clusters include our Development teams cluster (we do test, etc. here), our VDI cluster (where many of…

VMM 2012: How I got EMC Clariion AX4-5 Working with VMM Storage Mgmt Service

As I’ve started exploring System Center Virtual Machine Manager (VMM) 2012, the first task I took as an action item is to learn how to configure active management for our engineering EMC Clariion AX4-5.  I’ve personally been slacking a bit in getting VMM 2012 up & running.  As you probably have seen, we’ve been busy…

Changing Hyper-V Cluster Virtual IP Address (VIP) After Layer 3 Changes

We recently had a change take place in our engineering lab that included a large set of layer 3 changes (IP, VLANs, Subnets, etc.) that caused us some downtime.  Although most of the issues are well documented, I found though that there was one that simply plagued me in finding the resolution.  This was primarily…

Cluster Shared Volumes (CSV) – Extending a Volume

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…

Wait a minute… Virtual Machine isn’t “highly” available though it is on a Clustered Host?

It is possible, albeit an edge case, that you have both clustered (highly available) and non-clustered virtualization farms in your data center.  You’ve got your virtual machine (VM) configurations and hard disks stored on Cluster Shared Volumes (CSV) and your non-clustered VMs stored elsewhere (potentially on SANs but just not CSV’s).  It is recommended for…

Heading to MMS 2010 – One Presentation & lots of customer discussions…

As many of you already know, Microsoft is preparing for next week’s Management Summit 2010 in Las Vegas.  This is a great event, not only for his content but also its incredible knowledge transfer capabilities.  As a team member in the greater Management & Services Division (MSD) at Microsoft I can tell you this is…

SCVMM 2008 R2 & Cluster Shared Volumes (CSV) Migration from one CSV to Another

You often do your job of “planning” for your virtualization farm well in advance of when you can realistically foresee the amount of storage you will need.  If you like me, you often take the amount of known needed space and you triple it – shh, don’t tell management.  This technique works great until you…

Hyper-V Lingering Internal NICs – Unable to Remove

I recently had a Windows Server 2008 R2 server running the Hyper-V role with some Internal NICs created for private “sandboxing” of some VMs.  After adding some additional virtual machines to utilize the Private NICs, I was up and running.  This turned out to be a temporary situation until we put another server into production…
