group.

Removal of journal groups from an extended consistency group does not stop remote copy operations,

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.
