## Topology Snapshot

Use the Topology Snapshot function to create and update the topology view from the host or to review error details.

Note -

This function requires Solaris 8 4/01 or later.

Before you create a Topology snapshot, make sure there are no failed over paths. If there are failed over paths, the Topology view does not properly display them.

### Creating a Topology Snapshot

Use the Topology Snapshot function to create and update the topology view from the host or to review error details.

Before you create a Topology snapshot, make sure there are no failed over paths. If there are failed over paths, the Topology view does not properly display them.

1. From the Topology Maintenance window, click the Topology Snapshot link.

The Topology Snapshot window is displayed.

2. Select the check box that corresponds to the topology and click Create Selected Topologies. If you want to create a snapshot of all topologies, click Create All Topologies.

While the system creates the selected topology, the status is in one of two states:

3. Running-Discovery is running on the selected host, and the system creates and retrieves the selected topology.
4. Done-The topology has been created and is ready for you to retrieve.

1. Click the Review link to review the error details, if applicable.
2. Click the Clear link in the Delete column to clear a selected topology.

The Last Snapshot column contains the date of the last time a topology was extracted from this host.

The Last Master column contains the date the last Master Topology was sent back to that host.

### Reviewing Topology Error Details

- Click the link in the Error Details column to launch a pop-up window that displays topology errors.

Note -

If a timeout occurs during this process, you may need to increase the timeout specifications, using the System Timeout functionality. For information, see Changing System Time-Out Settings.
