Specifying a Tier
Describes how to associate a tier with a tiering-enabled volume using the Control System and the CLI.
About this task
NOTE
For a primer on Data Tiering, see Data Tiering.
Using the Control System, you can only associate an exiting tier (referred to as Remote Target in the Control System) with a volume enabled for Remote Archiving (or cold-tier). You cannot associate an existing tier with a volume enabled for Erasure Coding (or warm-tier) because the Control System allows a new tier to be automatically created when you enable a volume for erasure coding. If you want to associate an existing tier with a volume enabled for erasure coding, use the CLI or REST API to create the volume.Specifying a Remote Target Using the Control System
