Prerequisite information
•
Primary and secondary EXCTGs can be set up using Business Continuity Manager prior to
registering journals, or by using Remote Web Console in the following procedure.
•
Journals must be in Active or Stopped status.
•
Register master and restore journals in the separate EXCTGs.

Journals can be deleted from the EXCTG only if the attribute is Master, Restore, or Updating.

When Cnt Ac-J Z pairs are cascaded with Business Copy Z, and the BC Z T-VOL and a Cnt
Ac-J Z P-VOL share the volume, data consistency cannot be maintained when between primary
and secondary systems, even when journals are registered in an EXCTG.
•
When Cnt Ac-J Z pairs are cascaded with Continuous Access Synchronous Z, and the Cnt
Ac-S Z R-VOL and Cnt Ac-J Z P-VOL share the volume, make sure you enable the time stamp
transferring option of all the Cnt Ac-S Z pairs in the journal for data consistency.
•
Journals that can be used in a 3DC configuration with three Cnt Ac-J Z sites cannot be registered
in an EXCTG.
About the Add Journal window
Journals are registered to EXCTGs in the Remote Web Console Add Journals window. Please note
the following.
•
You can register journals in the primary or secondary EXCTG, from any of the four primary
or four secondary storage systems. You will specify the EXCTG that you want to register journals
in prior to landing on the Add Journals window. If you have not set up an EXCTG, a new
EXCTG is automatically created during the procedure.
•
The storage system you access in Remote Web Console is identified in the Add Journals
window as Local. This is true whether the system is a primary or a secondary system.
