REALLOCATE executed on System with LOSSCONN to CF and failed

After a loss of connectivity for 2 out of 14 z/OS images to a CF, the client put the problem CF in MAINTMODE and did a SETXCF REALLOCATE to clear the structures to do hardware recovery. The REALLOCATE process shifted to one of the 2 z/OS images th...

REALLOCATE TEST should provide more screening for potential structure duplexing issues.

REALLOCATE TEST needs to provide additional screening for potential structure duplexing issues. For example, if a REALLOCATE is performed while a structure is in simplex mode with DUPlEX(ENABLED) . and only failed-persistent structures, the REALLO...
