About changing tiering policy groups
This section describes how to make changes to tiering policy groups.
Changing a tiering policy
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
definition, and then apply the update to the storage system.
1. Change the tiering policy information CSV file.
2. Execute the KTIMPORT command.
The tiering policy group definition file is updated with the contents of the modified tiering policy
information CSV file.
