Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the z/OS V2R4 (or higher) NFS   *
  *                 Server that use the NFS Version 4 Protocol   *
  *                 with Linux or macOS clients.                 *
  ****************************************************************
  * PROBLEM DESCRIPTION: The z/OS NFS Server is enhancing the    *
  *                      mvsmnt server attribute to prevent NFS  *
  *                      Version 4 file handles from expiring    *
  *                      after server restart. Previously, the   *
  *                      mvsmnt attribute only helped recover    *
  *                      the file system of the mount point but  *
  *                      not any additional file systems         *
  *                      accessed under the NFS mount. This      *
  *                      support now extends that behavior to    *
  *                      include all file systems accessed under *
  *                      a mount point.                          *
  ****************************************************************
  * RECOMMENDATION: Install this PTF to enable the recovery of   *
  *                 NFS Version 4 file handles for all file      *
  *                 systems accessed under a mount point when    *
  *                 using the mvsmnt server attribute.           *
  ****************************************************************
  This APAR prevents NFS Version 4 file handles for all file
  systems accessed under a mount point from expiring after server
  restart when using the mvsmnt server attribute.
