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…

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…

Brocade Fiber Switch Console (Java) Shuts Down when Accessing via HTTP

If you run a lab or data center that includes Storage Area Networks (SAN) for shared storage then you’ve most likely run into switching technology.  For example, in our engineering lab we have 20+ physical hosts connecting to a fiber-based Host Bus Adaptors (HBA) and this requires the use of switches if you have more…

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…
