Monitoring TC operations history

You can review a pair's history of operations, including the operation's description, date and time it took place, primary and secondary system information, and other details.

To view a pair's operation history

1. Open the Replication window.

In Command Suite:

1. On the Resources tab, expand the Storage Systems tree.

2. Right-click the target storage system, and click Replication Dashboard.

In Device Manager - Storage Navigator:

1. Click Storage Systems, and then expand the Storage Systems tree.

2. In the Storage Systems tree, click Replication.

2. In the Replication window, click View History > Remote Replication.

3. In the History window, for Copy Type click TC .

4. The Description column displays operations. They are explained below.

Note the following when viewing histories:

• Operation rows may not appear in descending, chronological order.

• A maximum of 8,192 operation histories can be displayed.

• If a failed split occurred with two or more LDEVs at the same time, the number of pairs showing Pair Suspend (Failure) may not match the actual number of pairs in which the failure occurs.

• Even when performing TC pair operations to virtual storage machine volumes with CCI, LDEV ID displays the physical LDEV ID of the volume.

• If you use 1,000 or more pairs concurrently, some operation history might not be recorded.
