When the log data set being used to collect z/OS NFS server debug trace record becomes full or unusable, you can use switchlog to switch the trace recording to another log data set. Enter the operand as follows.

>>-+-MODIFY-+--mvsnfs,switchlog--------------------------------><
   '-F------'                     

where

switchlog

switches the z/OS NFS server debug trace recording from the current log data set to the next log data set. Prior to the switch, the in-storage debug trace information is flushed to disk and the current log data set is closed. Message GFSA930I is issued to report the log switch, including the previous and new log data set DD names, and debug trace recording continues in the next log data set.
