Active flashActive flash for mainframe workflow
The active flash feature of Dynamic Tiering can be set up using either Device Manager - Storage Navigator or RAID Manager.
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
RAID Manager 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
RAID Manager, see the
RAID Manager Command Reference and
RAID Manager User Guide. Use
Device Manager - Storage Navigator to create pools and
DP-VOLs.
- In RAID Manager, 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 RAID Manager automatically sets Tier Management to Manual. To change Tier Management to Auto, you must do this in Device Manager - Storage Navigator.
NoteIf you delete a pool, its pool-VOLs (LDEVs) will be blocked. If they are blocked, format them before using them.
