NAME    [Toc]    [Back]

       fs_config_data  -  Describes the configuration data for an
       AdvFS domain.

DESCRIPTION    [Toc]    [Back]

       The output of fs_save_config  contains  the  AdvFS  domain
       configuration that is used as input to the fs_restore_config
 function.  The configuration data file  entities  consist
  of  domains,  volumes,  filesets, mount points, disk
       groups and disk group disks,  all specified in XML markup.

       The fs_restore_config function requires that you provide a
       configuration remapping data file as input  to  the  function.
   The  remapping  data specifies how entities on the
       original system are remapped to the new system.

       For use of these functions, see their respective manpages.

NOTES    [Toc]    [Back]

       Leading  and trailing white spaces in the value of an element
 are ignored.

       A character data element must have a non-blank value.  For
       example,  <domain_name>  </domain_name> is not acceptable.
       This is true for both mandatory elements and optional elements.
   If no value is to be specified with optional elements,
 then there is no need to include their tags.

       Current  implementation  supports  processing  one   AdvFS
       domain at a time.

EXAMPLES    [Toc]    [Back]

       The  following are examples of configuration and remapping
       definitions that are the same for any type of domain  configuration.
  The  first  line is XML specific information,
       and must always be included.  The  following  shows  saved
       configuration data from a domain without LSM volumes. This
       data can be used as input to a remap.  <?xml version="1.0"
