This operand provides the ability to turn on extra debug controls to capture special diagnostics for specific functional areas in the z/OS NFS Server. Use this operand only when requested by IBM Support. Enter the operand as follows:

>>-+-MODIFY-+--mvsnfs,debug=-+-deleg----+----------------------><
   '-F------'                '-delegoff-'   

where

deleg

monitors the z/OS NFS Server NFS v4 delegation functions for the occurrence of various errors. If any of these errors are detected, a dump is generated to capture the associated NFS trace data before it is lost.

delegoff

turns off the special z/OS NFS Server NFS v4 delegation function monitoring. The writing of NFS trace records is not changed.

The default setting is for all of the debug controls to be off.
