Reconstructing the source and target units after the test

Before remote copy mode is resumed, the remote copy pair must be checked for data differences. After the tests the changes to the source unit are as a rule accepted and replication is resumed.

Keep the changes on the source units (i.e. all changes made on the target units during the recovery tests are discarded). Remote copy mode is restarted. Processing is once again to take place via the source path. /RESUME-REMOTE-COPY UNIT=<source_unit_MN> / *BY-PUBSET(PUBSET=<cat-id>) / *BY-VOLUME(VOLUME=<vsn>) >) / *BY-STORAGE(SERIAL-NUMBER=<local serialnumber> ,LOGICAL-VOLUME=*ALL-SOURCE-UNITS),WAIT=*UNTIL-SYNCH

The WAIT operand specifies whether the command waits for synchronization to be completed (WAIT=*UNTIL-SYNCHRONIZATION) or not (WAIT=*NO). This simplifies the programming of test procedures for recovery because extensive queries regarding the synchronization progress of the remote copy pair are unnecessary.
