Backup and Recovery Information

In certain situations, it might be necessary to contact SonicWall Technical Support, use SafeMode, or deregister the On-Premises Analytics instance:

• If the splash screen visible through the platform console remains displayed, this can indicate that the disk is corrupted. Please contact SonicWallTechnical Support for assistance.

• If the disk is not recoverable, then the instance needs to be deregistered with MySonicWall. See Deregistering Your On-Premises Analytics Instance for information.

• If On-Premises Analytics fails to boot, it may still allow access to the Management Console through the platform remote console. Check the platform webpage to ensure that the minimum required memory is available. If it still cannot boot up, check the logs at the Management Console, send diagnostics reports to technical support (see Diagnostics), and contact SonicWall Technical Support for assistance. For details on using the Management Console, refer to Using the Management Console.
