This topic applies to coupling facility log streams only. For DASD-only log streams, see Recovery performed for DASD-only log streams.

When all the systems in a sysplex fail, there are no peer connectors to perform the recovery processing for the failing systems, which would consist of offloading the coupling facility data for log streams to DASD log data sets or ensuring the duplex-mode structure is still intact. Coupling facility resident log data continues to exist. Further recovery processing depends on whether the coupling facility also failed.
