When the z/OS NFS server starts up, smf is set to off. You need to set smf to on if you want to collect the SMF records. The Network File System suspends writing SMF records when it detects an SMF error. The smf operand is used to resume or suspend the collection of SMF data. This operand has two parameters, ON and OFF. Enter the operand as follows.

>>-+-MODIFY-+--mvsnfs,smf=-+-off-+-[,-+-none---------+-]-------><
   '-F------'              '-on--'    +-all----------+     
                                      '-subtype_list-'     

where

smf=on

resumes the collection of SMF records.

smf=off

suspends the collection of SMF records.

smf=none

no SMF records are to be produced.

smf=all

all SMF NFS type 42 records are to be produced.

smf=subtype_list

a list of levels that are delimited by commas. At least one of the levels ( user | file | audit ) must be specified for a list, and the remaining levels are optional. Where:

• file: Produces file usages SMF records (subtype 7).
• user: Produces user session SMF records (subtype 8).
• audit: Produces file creation, removal, and rename records (subtype 26).
