Network File System reason codes are generic eight-digit hexadecimal codes that provide an indication of the problem location. They appear in the format 6nxxyyyy, where:

6D

Indicates NFS Client and Server Common Shared modules (that is, GFSNxxxx; for example, GFSNETRC).

6E

Indicates NFS Client modules (that is, GFSCxxxx).

6F

Indicates NFS Server modules (that is, GFSAxxxx).

xx

Is a two-digit hexadecimal number with one of the following values:

00 - 0F

Have special meaning. This range applies only to the z/OS NFS Client reason codes. See Special reason codes (xx is 00-0F).

10 - 3F

Identifies the NFS client module where the reason code was generated.

40 – FF

Identifies the NFS server module where the reason code was generated.

yyyy

Is a four-digit hexadecimal number with one of the following values:

0000 - 7FFF

NFS reason codes.

0000 - 0FFF

Reason codes that match USS JRxxxx reason codes. See Reason codes from NFS Client or NFS Server modules (xx is 10-FF).

1000 - 3FFF

Global reason codes that have the same meaning independent of module id. See Global reason codes (yyyy = 1000 - 3FFF).

4000 - 4FFF

Module specific reason codes. A given value has different meanings depending on the module id. See Module specific reason codes (yyyy = 4000 - 4FFF).

5000 - 70FF

Reserved

7100 - 73FF

Reason codes that match TCPIP JRxxxx reason codes. See z/OS UNIX System Services Messages and Codes.

8000 - FFFF

The line number of the location in the code where the error occurred. This line number is intended for IBM Service use only.
