ZOSMIGV2R3_NEXT_USS_SMB_DETECTED

Description:

The check examines all mounted file systems and issues an exception message if any of them are exported by Distributed File Service Server Message Block (SMB).

APAR OA56186 provides z/OSMF workflows to guide a system administrator through initial configuration of the z/OS NFS server and migration from DFS/SMB to z/OS NFS. For more information about those workflows, see z/OS Network File System Guide and Reference.

Reason for check:

z/OS V2.3 is planned to be the last release of the operating system to support the DFS/SMB functionality.

z/OS® releases the check applies to:

z/OS V2R2 and V2R3.

User override of IBM values:

The following sample shows the default keywords for the check, which you can override on either a POLICY statement in the HZSPRMxx parmlib member or on a MODIFY command. This statement can be copied and modified to override the check defaults:
