Here is an example of setting up the z/OS NFS client log data sets:

//NFSCMSG1  DD   DISP=SHR,DSN=MVSNFS.CLIENT.LOG1
//NFSCMSG2  DD   DISP=SHR,DSN=MVSNFS.CLIENT.LOG2    

File attributes of the z/OS NFS client log data sets can be set up like this:

Organization       PS
Record Format      VB
Record Length      137
Block Size         6144    

Reading the message(s) in the z/OS NFS client log data set can help you identify the user correctable error or the problem error which you can report to IBM®. See Client messages for an explanation of the format of the messages that appear in the z/OS NFS client log data sets.

The message GFSC313I in the example is an informational message (indicated by the message level I).

13:00:19 GFSC313I (I) CPARS 04 P_CHECK :
   RETRANS OPTION WILL BE IGNORED AS HARD OPTION IS ON.    

The message text indicates that the keyword, retrans, will be ignored because hard has been set on. The system programmer should check the mount parameters to make sure that hard should be on.
