Mixed-Architecture_Support

   All Extended File Specifications capabilities are available on
   OpenVMS Alpha Version 7.2 and later systems. Current ODS-2 volume
   and file management functions remain the same on both VAX and
   Alpha Version 7.2 (and later) systems; however, extended file
   naming and parsing are not available on VAX systems.

   The following topics describe support on OpenVMS VAX and Alpha
   systems in a mixed-architecture cluster.


   Limited Extended File Specifications Capabilities on VAX Systems

   In mixed-architecture OpenVMS Version 7.2 (and later) clusters,
   the following Extended File Specifications capabilities are
   available on OpenVMS Version 7.2 (and later) VAX systems:

   o  Ability to mount an ODS-5 volume

   o  Ability to write and manage ODS-2-compliant files on an ODS-5
      volume

   o  See only \pISO_LATIN\.??? or \pUNICODE\.??? when accessing an
      ODS-5 file specification


   BACKUP Limitations

   In a mixed architecture cluster, users cannot successfully create
   or restore an ODS-5 image saveset. However, these users can
   successfully restore ODS-2-compliant file names from an ODS-5
   saveset.
