Restoring a mounted user-defined file system

You can restore either just the objects within the mounted user-defined file system (UDFS), or restore both the UDFS information (/dev/asp/udfs_name.udfs) and the objects within the UDFS.

A UDFS, in the /dev/asp directory, is mounted over another directory. When you save the directory that the UDFS is mounted over, both the UDFS information and objects within the UDFS are saved.

In this example, the UDFS '/dev/qasp01/a.udfs' was mounted over directory '/appl/dir1' when directory '/appl/dir1' was saved. If you only want to restore the objects within the mounted UDFS, specify the following command:

RST OBJ(('/appl/dir1'))

The system restores the objects into the file system of the parent directory to which the objects are restored. The system does not restore UDFS 'dev/qasp01/a.udfs'.

When you recover from a disaster and if you saved your UDFS as mounted, use the following command to re-create the UDFS information during the restore operation:

RST  OBJ(('/directory_mounted_over'))
     RBDMFS(*UDFS)

Use the RBDMFS(*UDFS) parameter on the RST command to rebuild the mounted UDFS during the restore operation. However, if you omit the RBDMFS parameter or specify RBDMFS(*NONE), only the objects contained in the directory are restored, and none of the UDFS information is restored.
