Troubleshooting Compute Instances on Snowball Edge Devices

Following, you can find troubleshooting tips for Snowball Edge jobs with compute instances.

Virtual Network Interface Has an IP Address of

This issue can occur if the physical network interface (NIC) you associated with your virtual network interface (VNIC) also has an IP address of This effect can happen if the NIC wasn't configured with an IP address (for instance, if you've just powered on the device).

Snowball Edge Hangs When Launching a Large Compute Instance

It can appear that your Snowball Edge has stopped launching an instance. This is generally not the case. However, it can take an hour or more for the largest compute instances to launch.

To check the status of your instances, use the AWS CLI command aws ec2 describe-instances run against the HTTP or HTTPS Amazon EC2-compatible endpoint on the Snowball Edge.

My Instance Has One Root Volume

Instances have one root volume by design. All sbe instances have a single root volume, but with Snowball Edge, you can add or remove block storage based on the needs of your applications. For more information, see Using Block Storage with Your Amazon EC2-compatible Instances.

  1. Open a terminal and navigate to the location that you saved your .pem file to.

  2. Enter the following command.
