Usage Notes: 

If -F (force) is specified, the affected file(s) will be migrated regardless of normal disk residency criteria.
The -S option was added to provide a way to recover data from a second tape copy
- The underlying HPSS call applies only to open files, so note that each file to be migrated by this command will need to be opened. Use recursion and wildcards sparingly.

- The use of this command may be restricted at some HPSS sites.  

Example: 

migrate -F my_file
