Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When bringing up a z/OS 2.1 system in a non shared file system
  configuration, the following messages and errors may occur when
  bringing up automount:
  
  BPXF260I AUTOMOUNT POLICY WAS CHANGED AT 2014/05/31 00:43:11
  BY USER ibmuser ON SYSTEM SY1 WITH POLICY /etc/auto.master
  BPXF274I FILE SYSTEM *AMD/u FAILED TO MOUNT.
  RETURN CODE = 00000086, REASON CODE = 055B04AE
  
  This will occur if parent of target automount managed file
  system has been mounted as AUTOMOVE=UNMOUNT when running in non
  shared file system environment.
  

Local fix

• * Identify and unmount the parent file system containing the
  mountpoint for your automount managed directory. Once unmounted,
  mount this file system again without specifying the AUTOMOVE
  UNMOUNT attribute. Once mounted, automove status can be verified
  by looking at D OMVS,F output or ISHELL mount table.  Once
  mounted without UNMOUNT attribute, try running
  /usr/sbin/automount again.
  
     Example: If automount managing /usrs/usr1, with
     parent file system POSIX.USRS.HERE mounted at
     mount point /usrs, unmount POSIX.USRS.HERE and
     mount it again without UNMOUNT attribute. Note that
     a chmount or 'change attributes' from ISHELL will
     not succeed in changing AUTOMOVE setting in non
     sysplex environment.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of z/OS UNIX System Services for   *
  *                 HBB7790 using automount facility in the      *
  *                 non shared file system configuration         *
  *                 environment. The automount managed           *
  *                 directory resides in a file system that      *
  *                 is mounted with UNMOUNT attribute.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: In a single system environment,         *
  *                      mounting an automount file              *
  *                      system (*AMD/) failed with              *
  *                      ENOSYS RSN055B04AE when the AUTOMOVE    *
  *                      attribute of the file system            *
  *                      containing the directory that *AMD/     *
  *                      is to be mounted on is UNMOUNT.         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Automount file system (*AMD/) uses parent file system's owning
  system as its owning system when the parent file system has
  automove attribute UNMOUNT. FOMFAMT (automount facility) sets
  the sysname field with the parent's owning sysname and invokes
  the syscall mount. 'sysname' is a field for the sysplex
  enviroment and it's not allowed for mounting the file system
  in a single system environment. This causes mount processing
  to fail with ENOSYS JrMustBeSysplex in a single system
  environment.
  

Problem conclusion

• FOMFAMT is changed to check for the sysplex environment before
  it sets the sysname for mounting *AMD/.
