Create a copy group at the primary host.
To create a copy group:
1.
At the primary host, define a Cnt Ac-S Z copy group between the primary site and the local
site, and a Cnt Ac-J Z copy group between the primary site and the remote site.
2. At the primary site, define a Cnt Ac-J Z copy group for the delta resync function.
For the sub-consistency group ID (sub C/T ID(JNLG)) (the sub-consistency group ID for the
journal group), specify the same journal group number that was used for the S-VOL of the Cnt
Ac-J Z copy group, and for the mirror ID (MIRROR ID), specify a mirror ID other than the one
that was used for the Cnt Ac-J Z copy group.
