Removing Journal Groups from Extended Consistency Groups
You can remove journal groups from an extended consistency group anytime, regardless of
the status of the journal groups. Also, if you delete all data volumes from a journal group in
an extended consistency group, the journal group will automatically be removed from the
extended consistency group.
Removal of journal groups from an extended consistency group does not stop remote copy
operations, but does affect consistency in data update sequence. In the example in
below, if you remove the journal group 1 from the secondary
EXCTG, the remote copy operation from the primary storage system 1 to the secondary storage
system 1 will continue. However, consistency in data update sequence will only be maintained
among the primary storage systems 2 and 3 and the secondary storage systems 2 and 3.
