When you issue the XCOUPLE RELEASE command, XRC removes the coupled HOLD status of the master session. As a result, all coupled sessions in the master session remain coupled to this master session, and the coupled status for each session changes to NON-INTERLOCKED. You can then issue the XADDPAIR command (to add volume pairs to coupled sessions) and the XCOUPLE ADD command (to add new sessions to the master session). In addition, any update writes to primary volumes of coupled sessions changes the master recoverable time.
Attention: After you have issued the XCOUPLE command with either the RELEASE, DELETE, or PURGE parameter, data for the specified session may not be consistent with the other sessions in the master session.
For considerations when XRC sessions are coupled througha cluster session, refer to XCOUPLE RELEASE command considerations.
