HP StoreAll Storage - Manual (Page 182)

In this example, filesystem ifs1 has four segments and no tiering information is currently defined.
We will create two tiers, Tier1 and Tier2, and we will assign two segments to each tier.
On the Segments panel, select the segments for the tier and click Assign to Tier. On the Assign to
Tier dialog box, specify a name for the tier.
When you repeat the operation to place other file system segments in a tier, the dialog box allows
you to add the segments to an existing tier or to create a new tier.
When you create a tier, the tier assignment is added to the Segments panel. In the following
example, segments 1 and 2 are in Tier1 and segments 3 and 4 are in Tier2.
