Adding and removing devices in SAV

After you have opened and visualized devices in SAV and created your business application definition, you can add more devices to the initial snapshot in order to see how other devices — servers, network devices, and so on — relate to the current state of your business application.

For example, you might have created a business application but you are still not sure about all the network devices it might be using, or, you might see that there are a few managed servers that are connected to your business application, but that were not initially scanned. You can easily add these to the SAV application window.

Depending on your settings in the Add Devices window that you see when you add a device, SAV will automatically refresh the SAV snapshot and scan the selected devices. If you would rather not have SAV automatically scan any newly added devices, then you can add the devices, uncheck the check boxes in the window, and scan them later by clicking Refresh Snapshot on the SAV toolbar.

In some cases, you might find that some of the devices you have scanned are not necessary to your snapshot, and so you want to remove them. You can easily do so by selecting the device and selecting to remove it.

There are several potential errors that can occur when a Refresh or a device scan in SAV does not work. For a list of potential errors, see SAV scan error messages.

Adding devices to SAV

To add devices to SAV:

1. From anywhere inside of SAV, either right-click or from the Application menu, select Add Devices.
2. In the Add Devices window, in the left pane you can choose a device category, and the corresponding devices appear in the right pane. You can add servers, device groups, network devices, and so on.

   The Discovered Dependencies category shows any devices that SAV has discovered to be related to or connected to some of the devices in the existing SAV snapshot.

   The Refresh Scan Results option instructs SAV to automatically refresh the SAV snapshot when you click Add.

3. When you have selected the devices to add, click Add. Be sure to save the results or these newly added devices will not be saved in the Business Application.
4. If the Refresh Snapshot Results option was not selected, click Refresh Snapshot on the SAV toolbar so SAV will scan the newly added devices. Any devices that have been added to SAV without being refreshed appear as a translucent box in the maps and will not display any properties information.

Removing devices from SAV

To remove devices from SAV:

1. From inside of SAV, from one of the maps or the Devices pane, select a device, right click or from the Application menu, select Remove Devices.
2. You are asked to confirm that you want to remove the selected device. Click Yes to remove the device.
3. To make sure your SAV snapshot is up to date, click Refresh Snapshot on the SAV toolbar so SAV can update the snapshot and scan the newly added devices, and then save the Business Application.
   
   When a device is removed from a scan, the device and all connections to and from it and all external client IP addresses are removed in the maps, trees and tables, including links to other managed servers in the scan.
   
   When you click Refresh Snapshot, these lines to the other managed servers may display as a Client IP or other dependencies.

If you attempt to save or export the Business Application without refreshing the snapshot, a dialog appears asking if you want to save the Business Application. If you want the new information to be included in the Business Application, be sure to refresh the snapshot before saving or exporting.
