HWN024019W The following pools on tier tier_number on the storage_system storage system cannot be balanced by redistributing or re-tiering volumes: pool_names.
Explanation
The pools were not balanced either because volumes could not be re-tiered to balance the pools, or an insufficient number of volumes were re-tiered to reduce the activity level of the pools below the specified threshold.
Action
Complete one or more of the following actions, and then rerun the task to balance the pools:
- Select a wider range of pools on the tiers that you want to balance.
- Select a wider range of target pools on tiers that are higher and that are lower than the tiers that you want to balance.
- Increase the value for the activity limit of the pools that you want to balance.
