Update October 21st, 2011 (see bottom)
Let’s assume the following scenario:
- You have a Hyper-V R2 SP1 cluster that has three or more nodes
- You are using Cluster Shared Volumes
- You learnt about the Cluster Validation problem that was solved by KB2531907 back in May 2011, which prevented the “Failed to get SCSI page 83h VPD descriptors for cluster disk <number> from node <node name> status 2” error after running the Validate SCSI Vital Product Data. It also solved the “Disk with identifier <value> has a Persistent Reservation on it. The disk might be part of some other cluster. Removing the disk from validation set” error when running the List Potential Cluster Disks test. The hotfix resolves an issue in which the storage test incorrectly runs on disks that are online and not in the Available Storage group. The problem can also be caused by other issues such as storage problems or an incorrect configuration which means you have to check your storage configuration and check related events on your Hyper-V hosts.
- You want to add more capacity and add a new Hyper-V host.
Several hotfixes have been issued after the formal release of Windows Server 2008 R2 SP1. There was one particular hotfix in the making that we have really been waiting for. Many enthusiastic installers of SP1 in Hyper-V clusters with 3 or more nodes would face a problem with Cluster Validation. See the thread for more details.
We are glad that the hotfix has been made available today:
KB2531907 Validate SCSI Device Vital Product Data (VPD) test fails after you install Windows Server 2008 R2 SP1
A nice blog called Working Hard In IT by Didier van Hoye, describes all post SP1 hotfixes and can be found here.
Here are two RemoteFX hotfixes:
This culminating blog in a series on SCVMM 2012 shows how to create a Hyper-V R2 cluster in System Center Virtual Machine Manager 2012. With the arrival of Windows Server 2008 and 2008 R2, cluster creation has almost become a trivial job, largely because of the excellent Cluster Validation Wizard. The previous blogs showed us what preparations to make before we could perform a successful bare metal deployment. One moment you have 16 unconfigured blades, the other you have 16 fully installed Windows Server 2008 R2 hosts including the Hyper-V role. All that is left is to build a cluster from them … the easy way!
Because I didn’t have 16 available blades I had to settle for only two. But you’ll get the idea despite of this.
