## Displaying Topology History

With the Display Topology History function you can compare and delete current topology snapshots, and you can view, compare, or delete previously stored topology snapshots.

To display topology history:

1. Go to the Sun Web Console and click Storage Automated Diagnostic Environment.
2. Click Administration > Topology Maintenance > Topology History.

The Topology History window is displayed.

3. Do one or more of the following:

- To view a previously stored topology snapshot, click its displayed date.

The oldest snapshot is displayed first.

- To display a summary of the changes between two topology snapshots, select the check boxes for the two topology snapshot dates and click Compare Selected.

The host must have at least two topology snapshots for you to use the Compare Selected feature.

- To display a summary of the changes between the current topology and an archived topology snapshot, select the Current Topology check box and the check box for the topology snapshot date, and click Compare Selected.
- To delete a topology snapshot, select its check box and click Delete Selected.
