When the z/OS NFS server starts up, v4delg is set to off. Set v4delg to on if you want to enable NFS v4 MVS data set access delegation. The v4delg operand is used to resume or suspend delegation. This operand has two parameters, ON and OFF. Enter the operand as follows:

>>-+-MODIFY-+--mvsnfs,v4delg=-+-off-+--------------------------><
   '-F------'                 '-on--'   

where

v4delg=on

enables NFS v4 MVS data set access delegation.

v4delg=off

disables NFS v4 MVS data set access delegation.
