Product: ProfileUnity-FlexApp

Product Version: 6.5 +

Problem:

VHD ProfileDisk is not created on Windows 7, the backend device is Net App

 

Symptoms:

The "LwLLogonNotifier.log" found in c:\windows\temp\profileunity directory has following errors:

 

Detected error in command line result. Throwing Win32Exception.

Failed to run process. Error: The sector size of the physical disk on which the virtual disk resides is not supported

Failed to create VHD. Error: The sector size of the physical disk on which the virtual disk resides is not supported

Unable to continue with ProfileDisk operations. Exiting

 

Possible Resolution(s):

This is known Windows 7 limitation. This was addressed with Windows 8 and Server 2012.

The workaround is to change bit sector size on the NetApp device or use different operating system.

Please refer for more details to this LwL KB: 

VHD create error. "The sector size of the physical disk on which the virtual disk resides is not supported"

Note: Also windows VHDs "Thin Disks" (Expandable) are not supported by NetApp. The "Thin Disk" configuration should be done on NetApp device itself.
