After expanding a protected volume to more than 2TB, the VPG status will change to “Needs Configuration”
As ESXi 5.5.x and 6.0.x do not support hot disk expansion above 2TB. (Volume expansion of a powered on VM) The VRA on the target site, which can only perform a hot-expansion, will not be able to expand the disk. Therefore, the protected and mirror volumes will not match in size.

- Edit the affected VPG
- Take note of all the settings of the relevant VM and then remove it from the VPG (keeping recovery disks)
- Use the vmfstools command, as explained by the following VMware KB to expand the problematic disk to the exact same size as the protected volume: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1002019
- Re-add the VM to the VPG and set all disks to be preseeded. The VPG will go into a delta sync.
