Preparing
If a path failure has occurred between the primary site storage system and the intermediate site
storage system, use the Continuous Access Synchronous Z Consistency Preservation Function to
suspend the Continuous Access Synchronous Z copy pair. If a script of the following actions has
been executed before a path failure occurs, the processing necessary for failure recovery is
automatically executed after the failure.
For details on the Continuous Access Synchronous Z Consistency Preservation Function, see “The
Continuous Access Synchronous Consistency preservation function” (page 94) .
