Mapped volumes can be used in pairs for ShadowImage for Mainframe (VSP 5000 series) and ShadowImage. After you map and format an external volume, the volume can be used as a pair volume.
This figure shows an example of an external volume used as an S-VOL.
Note: When using a DP-VOL in Dynamic Provisioning, Dynamic Tiering, or active flash, follow Restrictions on copying volumes using Universal Volume Manager with DP-VOLs.
