RDM LUN Size not properly updating on ESXI/vCenter after resize of LUN

VMware vSphere ESXi
Issue/Introduction
After performing a resize of the LUN at the array level it's not being reported properly on the vCenter/ESXI side.
From the Storage Array it shows the new size added on the LUN however vCenter Server shows the old information.
Performing a rescan of the Storage does not update the size properly.
De-attaching the LUN does not resolve the issue.

Cause
This issue has been noticed with RecoverPoint from EMC.
RecoverPoint is a Storage Replication software to replicate LUNs from one site to the other site.
As per EMC documentation;
" In the RecoverPoint system, data consistency and write-order fidelity are maintained across all volumes, by replication sets.
Therefore, when you wish to add storage capacity to a particular volume, you must resize all of the volumes on the replication set.
When a LUNs storage capacity changes on the host storage system, the volume representing the LUN in RecoverPoint must be removed from and then re-added to, the RecoverPoint System.
For the change in the LUN size to be reflected in RecoverPoint. "
In this case this applied as well for ESXI/vCenter, we need to remove the LUN from the replication set and perform a Rescan of the storage.
After doing so, we should be able to report back the correct size.
