Restoring a Previous Client Configuration

Chapter 2 Installing StorNext File System

Installing StorNext File System on Windows

8Click Install to continue.

Wait while the setup wizard installs StorNext. When installation is complete, the Finish window appears (figure 15).

9Click Finish to close the setup wizard.

10On the StorNext Installation window, click Exit. You are prompted to reboot the system.

11Click Yes to reboot.

You can now configure StorNext File System. For more information, see Chapter 4, “Configuring StorNext.” Or, to restore a previous client configuration, see the next section.

If you saved a client configuration file (for example, when removing a previous version of StorNext), you can import it after installing StorNext. This configures StorNext using the same settings as the previous installation.

1Insert the StorNext installation CD.

2Browse to the root directory of the installation CD and double-click the file SnfsSetup32.exe (32-bit systems) or SnfsSetup64.exe (64-bit systems).

The StorNext Installation window appears (figure 16).
