Figure 21 BC and Continuous Access XP: shared S-VOL/P-VOL
Usually Continuous Access XP and Continuous Access XP Journal can share volumes with BC. However,
in some cases, you cannot create BC pairs using volumes shared with Continuous Access XP and
Continuous Access XP Journal. Figure 22 and Figure 23 show examples of when you cannot create BC
pairs using volumes shared with Continuous Access XP and Continuous Access XP Journal.
NOTE:
A Continuous Access XP Journal primary volume (P-VOL) means a Continuous Access XP Journal
primary data volume. A Continuous Access XP Journal secondary volume (S-VOL) means a Continuous
Access XP Journal secondary data volume.
Figure 22 is an example of a volume functioning as both a Continuous Access XP Journal S-VOL and a
Continuous Access XP P-VOL. In this configuration, you cannot use this volume as the P-VOL of a BC pair.
