Question:

Does TPX support Coupling Facility Structure Rebuild?

Answer:

TPX supports rebuilding and altering of the TPX Coupling Facility (CF) structure by the operating system. End users will see messages indicating that sign on or sign off is not possible during recovery.

If TPX attempts to connect to a CF structure during rebuild, a message will be issue to the console and TPX will wait 30 seconds before attempting to connect again.
