commands
This section describes how to change tiering policy groups by using CLI commands.
Changing a tiering policy when using the CLI commands
If you need to change a tiering policy due to lowered I/O performance or a change in the purpose
for which volumes are being used, modify the created tiering policy information CSV file, update the

2. Execute the KTIMPORT command.
The definition of the tiering policy group is updated with the contents of the modified tiering
policy information CSV file.
