Mapped external volumes can be used by the following programs:
- Dynamic Provisioning
- Dynamic Tiering
- active flash
- Thin Image
Note the following restrictions:
- If you are using a Thin Image pool, all external volumes in the same pool must use the same Cache Mode setting. For more information about this setting, see Cache use and external storage performance.
- (VSP 5000 series) A mapped volume that is used as a pool volume must use OPEN-V emulation for open systems and 3390-V emulation for mainframe systems.
- (VSP E series) With Dynamic Tiering, Cache Mode must be set to Enabled.
- (VSP E series) Mapped external volumes can be used as quorum disks for global-active device, but not as pair volumes.
