All CF structures for IBM® software support a rebuild process (either user-managed or system-managed). Before rebuilding a structure into an alternate CF, ensure the alternate CF has sufficient connectivity and memory capacity. The alternate CF must be in the preference list of the structure to be rebuilt. If necessary, create a new CFRM policy (or modify an existing CFRM policy) with the alternate CF in the structure preference list and activate it. See Planning a coupling facility policy for more information. Start a CF structure rebuild process that will rebuild the structure into another CF using the SETXCF START,REBUILD,STRNAME=strname,LOCATION=OTHER system command.

Rebuilding a structure might take several minutes to complete. A response to the rebuild request indicates if the rebuild has been successfully initiated, and a message will be issued when the initiated rebuild processing actually completes.

To perform this function for multiple structures, REALLOCATE and rebuild by CFNAME can also be used. See also "Using REALLOCATE or POPULATECF to relocate coupling facility structures" in Managing coupling facility resources.
