Provisioned Storage incorrect when using RDMs

Hi all,

I have a couple of virtual machines which are part of a Microsoft cluster.  They have RDM's and are using physical bus sharing.  The RDMs have been expanded by changing the size on the SAN, rescanning the ESXi host, and finally expanding the volume on the VM.  The LUN size reports correctly on the ESXi host but the provisioned storage and size from a Get-HardDisk command is incorrect.  Running a "Refresh Storage Usage" on the VM does not help.

Any ideas how I can get these reporting correctly?

Thansk for your help,
