For example:
If additional capacity is added to the pool and the capacity defines a new Tier 1 or new Tier 2, then the THP V-VOLs
with a Level 5(5) assignment will not physically move but Level 5(5) will be associated with Tier 3.
If additional capacity is added to the pool and the capacity defines a new Tier 3, the THP V-VOLs with a Level 5(5)
assignment will physically move to the new Tier 3 and Level 5(5) will be associated with Tier 3.

Viewing the tiering policy in the performance graph

You can view the frequency distribution graph of the pool by selecting either the level of the tiering
policy or the entire pool on the performance graph in the View Tier Properties window.
The following table shows how tiering policy is shown in the performance graph. How the graph
appears depends on the number of tiers set in a pool and tiering policy level selected when viewing
the performance graph.
