Please consider moving this question as-is (no need to recreate) to the proper forum for maximum visibility. Questions written to the users' own "Discussions" space don't get the same amount of attention and can go unanswered for a long time.
You can do so by selecting "Move" under ACTIONS along the upper-right. Then search for and select: "VNX Support Forum".
When used with FAST VP, it is recommended to only use Storage DRS for capacity load balancing/(initial) placement and to *disable* I/O metrics on the corresponding datastore associated with the FAST VP LUN (LUN with an active tiering policy). Then as you are certainly familiar with, FAST VP will then rebalance slices amongst tiers and/or (assuming VNX OE for Block v32) within the same tier based on activity (or lack of). This is mentioned in several EMC publications as well as VMware documents and blogs. For example:
