44 Business Copy XP (BC) for the XP10000/XP12000
NOTE: This configuration does not allow BC and Continuous Access XP to copy at the same time. Create
the BC pair first, and then split the pair before creating the Continuous Access XP pair. You must suspend the
Continuous Access XP pair to resync the BC pair. The Continuous Access XP pair status cannot be changed
when the BC pair is in PSUS(SP) status.
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.
