Note:
In the configuration shown in
on page 36, you cannot perform the Business Copy and
Continuous Access Journal copy operations at the same time. In
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
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.
