Using SafeMode on the NSv

The NSv virtual machine enters SafeMode when SonicOS/X restarts three times unexpectedly within 200 seconds. When the NSv virtual machine is in SafeMode, the virtual machine starts with a very limited set of services and features enabled. This is useful when trying to troubleshoot issues. The NSv virtual machine can also be configured to boot into SafeMode by using the Reboot | Shutdown screen in the NSv management console.

How Management Console Differs in SafeMode

In SafeMode, some of the features the management console provides are different in the following ways:

• Configurable interfaces

• Configurable default gateway

• Configurable DNS servers

  Changes made to interfaces in SafeMode are not persistent between reboots.

When the NSv is in SafeMode, the SonicOS/X service is one of the services that is not enabled and is shown as Not operational on the SafeMode System Info screen.

Entering SafeMode

After booting into SafeMode, the Management Console always starts with the System Info screen.

To exit SafeMode, disable it on the Reboot | Shutdown screen or deploy a new firmware image. See Disabling SafeMode and Installing a New SonicOS/X Version in SafeMode for more information.
