How to create a workload placement for a VM with storage on multiple datastores

I have had the need for this for a long time, and I have tried many ways to make this work with no success.

We have 2 Clusters, with the following Datastores

 

Cluster-1

DS-High-1-lun101

DS-High-3-lun103

 

DS-Medium-1-lun111

DS-Medium-3-lun113

 

DS-Low-1-lun121

DS-Low-3-lun123

 

DS-Templates-lun140

DS-Swapfiles-lun151

 

Cluster-2

DS-High-2-lun102

DS-High-4-lun104

 

DS-Medium-2-lun112

DS-Medium-4-lun114

 

DS-Low-2-lun122

DS-Low-4-lun124

 

DS-Templates-lun140

DS-Swapfiles-lun152

 

Most of our datastores are replicated to our disaster recovery site using recoverpoint. To cut down on our replication traffic and increase our recovery window, all of our VMs are configured to have the pagefile for the OS on a dedicated disk on DS-Swapfiles-lun-151 which is not replicated.

 

Here is the problem:

VirtualServer1

OS             C: DS-Medium-2-lun112

Data           D: DS-High-2-lun102

PageFile     S: DS-Swapfiles-lun151

 

Sometimes VMT makes recommendations to move VirtualServer1 to DS-Swapfiles-lun-151.

Sometimes VMT makes recommendations to move VirtualServer1 to DS-Low-2-lun122.

 

1) How do I set a workload placement so that VMTurbo does not look at DS-Swapfiles-lun152 as a datastore to move VMs to?

2) How do I set a workload placement policy so that VMTurbo can recommend to migrate the host only to the similar drive pool that the drives are currently in? For example Say VirtualServer 1 C: can only be hosted on DS-Medium-2-lun112 or DS-Medium-4-lun114.

3) I also get recommendations to migrate templates that are stored in DS-Templates-lun140 to the other luns as well which we don't want.

Hope that makes sense.
