Cluster Shared Volumes status becomes Online (Redirected access)
Technical Articles ID:   KB73596
Last Modified:  7/19/2016


McAfee VirusScan Enterprise (VSE) 8.8 Patch 1 and later

Microsoft Windows 2008 R2 


After you install VSE 8.8 Patch 1 or later, HyperV servers on Windows 2008 R2 show Cluster Shared Volumes (CSV) as:

 Online (Redirected access)

If you try to bring the shared volume online, you see the following error:

The Action 'Turn off redirected access for this Cluster Shared Volume' did not complete.

NOTE: VSE functionality is not impacted.

If you run the fltmc command, it reports the following:

Filter Name
Num Instances
Altitude Frame
404900 1
329998.99 <Legacy>
321300.00 0

System Change

You installed VSE 8.8 Patch 1 or later.


Each filter instance requires a unique altitude.

The whole-number portion is pre-assigned so the suffixes (.00) through (.99) are used to deal with upgrade scenarios where a new filter version must coexist with a previous one until you restart your computer. This usage is consistent with Filter Manager's own method of dealing with <legacy> filters.


Microsoft has confirmed that a Cluster (Windows 2008 R2) will put a CSV in redirected mode if a filter’s Altitude is not an integer.

Microsoft Knowledge Base article 2674551 (https://support.microsoft.com/en-us/kb/2674551) includes a hotfix and instructions to resolve the issue where Redirected Mode is enabled unexpectedly in a CSV when you run third-party applications in a Windows Server 2008 R2-based cluster.
