This procedure allows you to associate a DataClass group
definition with a directory. All files and directories beneath the
association point are included in and governed by the DataClass
group parameters.
To add a DataClass group association to a directory, it must not
be superior to or subordinate to any directory that already has a
Directory-to-DataClass relationship.
If the subdirectories already have the same DataClass
relationship, the association point can be rolled up. For more
information, see “Change Relation Points” on page 2-17.The
DataClass association point cannot be a directory in the
root
file system unless it is a mount point for a new file system.
The DataClass group associated with a directory also
determines the media to which the files in that directory is
migrated. The files in a migration directory are only migrated to
media that contain files with the same DataClass group
association.
Associate New Data
with New Relations
After adding a new relation, run the fsdump command to
associate any new data with the new relation (the new mount
point).
The fsdump command creates an fs_dump.file that
contains an entry for each associated directory and stored file in
the file system. The
fsaudit command uses the
fs_dump.file to reconcile the restored files from the dump
tape and the FileServ database.
Caution
Failure to run fsdump after adding relations may impact
system performance.
