Recalling older generations of a file
An administrator can recall any older generation of a migrated file using the fsefile command
executed on the FSE client. The fsefile command is also used to show file history with information about
older migrated generations of a file on an HSM file system. For further information about using the
fsefile command, see the FSE Command-Line Reference.
NOTE: The fsefile command can be used only on files which are located on a local HSM file system.
The procedure for recalling an older generation of a migrated file is the same on all supported platforms.
The main difference in the examples that follow is in the pathnames used.
Recalling an older generation of a migrated file may take some time. The command, however, starts a
recall job and returns quickly without a message if the job has been started successfully.
NOTE: Permissions, ownership, and dates change on recall. Creation time, modification time, and access
time are set to the current time when the file has been recalled.
Linux specific
The ownership of the recalled older file generation is set to root.
Example output of the fsefile --history command
