1st of all there is nothing called "Volume Tiering"
The concepts called "Automated Tiering" and "Volume Tier Affinity".
Now in MSA Virtualization if I assume you have all 3 type of drives likes SSD, Enterprise SAS and Midline SAS then you can have Performance, Standard and Archive Tier.
We create disk-groups as per the drive types. In this example I assume we have created three different disk-groups as per 3 different drive types.
I assume all these 3 disk-groups part of same Pool
Now when we create Volume of some particular size that time MSA just create that size volume by taking space from that Pool. You will not come to know from which tier or disk-group space or pages will be allocated. This is Virtualization.
Now lets say you have created two volumes. Like you said D and E drives. In Automated Tiering or Volume Tier Affinity data never move between one Volume to another volume. In case of AUtomated Tiering pages moved between one tier to another tier based on usage and hot demand of pages. May be you can go through same Best Practice guide and go through details of "Automated Tiering" to get more details on this.
Now coming to "Volume Tier Affinity"..........this is not like Tier Pinning where pages must move to some particular tier. I would suggest to go through same Best Practice guide and go through "Mechanics of Volume Tier Affinity" . This will give clear idea regarding this.
Hope this helps!
