The message supplied by the file security exit is sent to the NFS server log data set and component trace, if activated. The message has the label name FEDSXD and consists of the following two fields.

FEDSXCNT

1 byte message length, excluding the NULL character (X'00').

FEDSXMGS

81 byte NULL character string. The installation-wide exit can fill in this message field with an error message ended by one or more bytes of X'00'.

If the format of the message is incorrect, the file security installation-wide exit is marked as nonexistent, and a message (GFSA990I or GFSA991E) is sent to the NFS server log data set and to the console, and to component trace if activated.
