source volume (S-VOL)
Used only in the earlier version of the Device Manager - Storage Navigator GUI (still in use). This is the volume in a mainframe copy pair containing the original data that is duplicated on the target volume (T-VOL). The following Hitachi products use the term source volume: ShadowImage for Mainframe, Dataset Replication, and Compatible FlashCopy®.
In the current version of the GUI, "target volume" and "T-VOL" are replaced with "primary volume".
