Setting up the z/OS NFS server log data set

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

//NFSLOG1   DD   DISP=SHR,DSN=MVSNFS.PROCESS.LOG1
//NFSLOG2   DD   DISP=SHR,DSN=MVSNFS.PROCESS.LOG2

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

Organization       PS
Record Format      VB
Record Length      137
Block Size         6144

See Network File System operation and Log operand to find out how to set the level of messages to be stored in this data set. The default message level is “info” which means that all error, attention, and informational messages are collected and stored in the z/OS NFS server log data set. Reading the message(s) in the z/OS NFS server log data set can help you identify the user correctable error or the problem error which you can report to IBM. See Server messages for an explanation of the format of the messages that appear in the z/OS NFS server log data sets.

This example shows how to identify a sample problem by reading the z/OS NFS server log data set. This example shows a z/OS NFS server log data set with the message level set as “info” (informational):

20:25:16 GFSA305I (I) GFSAMAIN ACOPR 01 OPRPARSE: RECEIVED
   COMMAND: EXPORTFS , LENGTH = 9
20:25:16 GFSA865I (E) GFSAMAIN ANEXP 03 DOOPTION: EXPORTS:
   UNEXPECTED OPTION (PO)--EXPORTS FILE UNUSABLE.
20:25:16 GFSA866I (E) GFSAMAIN ANEXP 07 EXPORTAL: EXPORTS:
   DIRECTORY (TCP) WAS NOT EXPORTED.
20:25:16 GFSA925I (E) GFSAMAIN AXOPE 02 OPR_EXPO: ERROR WAS
   DETECTED IN THE EXPORTS FILE. EXPORT LIST NOT REBUILT
20:25:34 GFSA305I (I) GFSAMAIN ACOPR 01 OPRPARSE: RECEIVED
   COMMAND: FLUSHLOG , LENGTH = 9
⋮

The message GFSA865I in the example is an error message (indicated by the message level E).

20:25:16 GFSA865I (E) GFSAMAIN ANEXP 03 DOOPTION: EXPORTS:
   UNEXPECTED OPTION (PO)--EXPORTS FILE UNUSABLE.

The message text indicates that the option “PO” specified in the DIRECTORY statement in the exports data set is not a valid option. You could correct this error by changing “PO” to “RO” and restarting the server.
