Hi

on one of the blogs i am following, Adian Finn, he has a post about a new hotfix from Microsoft that has come out regarding a problem with Hyper-V clusters and CSV volumes in redirected mode, read more at this link and get the hotfix

Consider the following scenario:

• You enable the cluster shared volume (CSV) feature on a Windows Server 2008 R2-based failover cluster.
• You create a virtual machine on the CSV on a cluster node.
• You start the virtual machine on the cluster node.
• You move the CSV owner to another cluster node, and you change the state of CSV to redirected access.
• The connection that is used for redirected access is switched to another connection when one of the following scenarios occurs:
  • The cable for local area network (LAN) is disconnected.
  • The related network adapter is disabled.
  • The connection is switched by using Failover Cluster Manager.

In this scenario, you receive a Stop error message that resembles the following in the virtual machine:

Note

• The parameters in this Stop error message vary, depending on the configuration of the computer.
• Not all “0x0000007a” Stop error messages are caused by this issue.
• You may also receive other Stop error messages when this issue occurs. For example, you may receive a “0x0000004F” Stop error message.
