128 Best practices
5. Activate the files in the target directory.
Description:
Activating a file means that FMA’s metadata is synchronized to the new system file ID. This step enables
the link to the archive copy.
6. Delete the source directory
Relocating a large number of files
If the relocation process is required for a large number of files and only a short production downtime is
available, the command for disabling the files could also be executed after the target directory has been
enabled for user access and before deleting the source directory. In this case, the downtime is decreased
by the processing time of the command for disabling the files.
This procedure is feasible under the following conditions:
• User and/or application access to the source directory must be permanently revoked before starting the
relocation procedure.
• User and/or access to the target directory must be avoided until all files have been activated using the
command fmacli act.
• The administrator must guarantee that the command for disabling the files in the source directory has
been executed before deleting them.
Steps for relocating a large number of files:
1. Revoke access to the file systems of the source and target directories.
2. Make sure that your data has been backed up.
3. Copy your data using the NoRecRobocopy command and check that all files have been copied
successfully.
Example:
4. Activate the files in the target location.
5. Grant access to your target location.
6. Deactivate the files in the source location.
7. Delete the files in the source location.
