To start the access status data synchronization process, the settings for the Primary storage and the Secondary storage of the Storage Cluster environment must satisfy the following conditions:
The FTV that is defined in the TFO group is included in the Tier pool that has a one-to-one relationship.
Automated Storage Tiering of another Tier pool where the access status data is synchronized is running.
The chunk size of the Tier pools for synchronizing the access status data is the same.
When the access status data synchronization is set to "enable" and all the above conditions are satisfied, if Automated Storage Tiering is started, the access status data synchronization process between Tier pools is started.
Point
If the access status data synchronization process has started, the Tier pool name that started Automated Storage Tiering is added to the operations log when Automated Storage Tiering for Tier pool was started and the Tier pool name of the another synchronization target is displayed.
Example
Configuration examples of when access status data synchronization is executed/not executed are shown below.
Environment example for performing access status data synchronization
For a single TFO group, the Tier pool is in a one-to-one relationship
For multiple TFO groups, the Tier pool is in a one-to-one relationship
Environment example where the access status data synchronization is not performed
For a single TFO group, the Tier pool is in a one-to-N relationship
For multiple TFO groups, the Tier pool is in a one-to-N relationship
