CPF propagates commands from PLEX1 to PLEX2.
CA-ACF2 LIST command using CPF with TARGET operand propagates to other node but nothing is returned.
LIST TESTID TARGET(PLEX2)
By default due to CPF OPTIONS field NOCMDWAIT, CPF will run asynchronous. So there are two options to get the commands returned. Change the OPTIONS record to CMDWAIT, or use the override on the command line CPFWAIT.
LIST TESTID TARGET(PLEX2) CPFWAIT
