Besides the start and stop commands, you can enter the modify command at the console with thee operands shown in the summary of the modify command later in this section. All operands must be preceded by either MODIFY mvsnfs, or F mvsnfs, where mvsnfs is the name of the procedure in your system PROCLIB used to start the server.

Each message is sent to a component trace buffer, or to the console or the data set that is pointed to by the NFSLOG1 and NFSLOG2 DD statements, or to any combination of those destinations. NFSLOG1 and NFSLOG2 are DD statements in the startup procedure of the z/OS NFS server. These z/OS NFS server DD statements specify data sets where all the messages for debugging or trace are stored during the processing of the z/OS NFS server.

All data set names entered from the console must be fully-qualified and without quotation marks.

This is a summary of the modify command with the relevant operands:
