Figure 16 Shared Volumes of Business Copy and Continuous Access Journal:
P-VOL/P-VOL and P-VOL/S-VOL
The configuration shown in Figure 17 on page 36 is an example of a volume that is functioning as both
a Business Copy S-VOL and a Continuous Access Journal P-VOL. This configuration allows you to use
Continuous Access Journal to provide remote copies of Business Copy S-VOLs.
Figure 17 Shared Volume of Business Copy and Continuous Access Journal:
S-VOL/P-VOL
Note: In the configuration shown in Figure 17 on page 36, you cannot perform the Business Copy and
Continuous Access Journal copy operations at the same time. In Figure 17 on page 36, first you need to
create and split the Business Copy pair, then create the Continuous Access Journal pair. To resynchronize
the Business Copy pair, suspend the Continuous Access Journal pair beforehand. Note that you cannot
change the Continuous Access Journal pair status while the Business Copy pair is in PSUS(SP) status.
Continuous Access and Continuous Access Journal
Although Continuous Access and Continuous Access Journal can each share volumes with Business Copy,
they cannot share Business Copy volumes in some combinations.
The configuration shown in
Figure 18 on page 37 is an example of a volume functioning as both a
Continuous Access Journal S-VOL and a Continuous Access P-VOL. In this configuration, you cannot use
this volume as the P-VOL of a Business Copy pair.
