The system was trying to establish EXTENDED PDSE sharing. An error occurred when membername attempted to join XCF group groupname.
This is an error situation which can occur during ordinary system operation or during system shutdown. While this message remains on the MVS™ console, any shared PDSEs which are open on this system may be inaccessible by other systems.
If this system hangs with this message on the console other systems may have problems accessing some PDSEs. As the system completes shutdown or is restarted, the message will disappear and the PDSEs will be usable.
This system will run with the NORMAL sharing option. Until the inability to join the XCF group is resolved, this system cannot run the EXTENDED option.
Notify the system programmer.
