You can review a history of the tasks you have completed on a pair from the History window in HDvM - SN. The storage system stores a history of up to 1,024,000 of the last tasks. If you use 1,000 or more pairs concurrently, some operation history might not be recorded.

Note: You can also check the task history of SI pairs by using audit logs. For details, see the Hitachi Audit Log User Guide.

In the Explorer pane, click Storage Systems, expand the storage system tree, and then click Replication.
In the Replication window, click View History, then click Local Replication.
In the History window, for Copy Type, select SI.
