Active flash workflow

The active flash feature of Dynamic Tiering can be set up using either Device Manager - Storage Navigator or Command Control Interface.

The following illustration shows the workflow for a Storage Administrator to set up active flash on the storage system. As shown in the illustration, Device Manager - Storage Navigator and Command Control Interface have different workflows. The details about how to set up active flash using Device Manager - Storage Navigator are covered in subsequent topics. For details about how to set up active flash using Command Control Interface, see the Command Control Interface Command Reference and Command Control Interface User and Reference Guide. Use Device Manager - Storage Navigator to create pools and DP-VOLs.

• In Command Control Interface, when creating a pool, you cannot enable Multi-Tier Pool and cannot register multiple media as pool-VOLs. Before making tiers, enable Multi-Tier Pool.

• Enabling Multi-Tier Pool from Command Control Interface automatically sets Tier Management to Manual. To change Tier Management to Auto, you must do this in Device Manager - Storage Navigator.

 If you delete a pool, its pool-VOLs (LDEVs) will be blocked. If they are blocked, format them before using them.
