Configuring and using the Snowball Edge Client
The Snowball Edge Client is a command-line interface (CLI) tool from AWS that you can use to work with a Snow Family device or a cluster of Snow Family devices. You can use the client to unlock a Snow Family device or cluster of devices, set up Snow Family devices, start and stop services on devices, and transfer data to or from devices. The Snowball Edge client is compatible with computers running on Linux, macOS, and Windows operating systems.

Downloading and installing the Snowball Edge Client
You can download the Snowball Edge Client from
AWS Snowball Edge Resources
Install and configure the client according to the instructions below.
Configuring a profile for the Snowball Edge Client
Every time you run a command for the Snowball Edge Client, you provide your
manifest file, unlock code, and the IP address of the Snow Family device. Instead of providing these each time you run a command, you can use the configure
command to
store the path to the manifest file, the 29-character unlock code, and the endpoint (the IP address of the Snow Family device) as a
profile. After configuration, you can use Snowball Edge Client commands
without having to manually enter these values for each command by including the profile name with the command. After you
configure the Snowball Edge Client, the information is saved in a plaintext JSON
format to
. Make sure your environment is configured to allow you to create this file. home
directory
/.aws/snowball/config/snowball-edge.config
Important
Anyone who can access the configuration file can access the data on your Snowball Edge devices or clusters. Managing local access control for this file is one of your administrative responsibilities.
You can also use AWS OpsHub to create a profile. Profiles created in AWS OpsHub are available to use with the Snowball Edge Client and profiles created in AWS OpsHub are available to use with the Snowball Edge Client. For more information, see Managing profiles.
To create a profile
Enter the command in the command line interface for your operating system. The value of the
profile-name
parameter is the name of the profile. You will provide it in the future when running Snowball Edge Client commands.snowballEdge configure --profile
profile-name
The Snowball Edge Client will prompt you for each parameter. When prompted, enter the information for your environment and the Snow Family device.
Note
The value of the
endpoint
parameter is the IP address of the Snow Family device, prefaced byhttps://
. You can locate the IP address for the Snowball Edge device on the LCD screen on the front of the device.Example output of
configure
commandConfiguration will stored at home directory\.aws\snowball\config\snowball-edge.config Snowball Edge Manifest Path:
/Path/to/manifest/file
Unlock Code:29 character unlock code
Default Endpoint:https://192.0.2.0
The Snowball Edge Client will check that the unlock code is correct for the manifest file. If they do not match, the command stops and does not create the profile. Check the unlock code and manifest file and run the command again.
To use the profile, include --profile profile-name
before the command syntax.
If you are using multiple, standalone Snow Family devices, you can create a profile for each. To create another profile, run the configure
command again, provide a different value for the --profile
prameter, and provide the information for another device.
Example snowball-edge.config
file
This example shows a profile file containing three
profiles—SnowDevice1profile
,
SnowDevice2profile
, and SnowDevice3profile
.
{"version":1,"profiles": { "SnowDevice1profile": { "name":"SnowDevice1profile", "jobId":"JID12345678-136f-45b4-b5c2-847db8adc749", "unlockCode":"db223-12345-dbe46-44557-c7cc2", "manifestPath":"C:\\Users\\Administrator\\.aws\\ops-hub\\manifest\\JID12345678-136f-45b4-b5c2-847db8adc749_manifest-1670622989203.bin", "defaultEndpoint":"https://10.16.0.1", "isCluster":false, "deviceIps":[] }, }, "SnowDevice2profile": { "name":"SnowDevice2profile", "jobId":"JID12345678-fdb2-436a-a4ff-7c510dec1bae", "unlockCode":"b893b-54321-0f65c-6c5e1-7f748", "manifestPath":"C:\\Users\\Administrator\\.aws\\ops-hub\\manifest\\JID12345678-fdb2-436a-a4ff-7c510dec1bae_manifest-1670623746908.bin", "defaultEndpoint":"https://10.16.0.2", "isCluster":false, "deviceIps":[] }, "SnowDevice3profile": { "name":"SnowDevice3profile", "jobId":"JID12345678-c384-4a5e-becd-ab5f38888463", "unlockCode":"64c89-13524-4d054-13d93-c1b80", "manifestPath":"C:\\Users\\Administrator\\.aws\\ops-hub\\manifest\\JID12345678-c384-4a5e-becd-ab5f38888463_manifest-1670623999136.bin", "defaultEndpoint":"https://10.16.0.3", "isCluster":false, "deviceIps":[] } }

Finding Snowball Edge client version
Use the version
command to see the version of the Snowball Edge command line interface (CLI) client.
Usage
snowballEdge version
Example output
Snowball Edge client version: 1.2.0 Build 661
Getting credentials for a Snow Family device
Using the snowballEdge list-access-keys
and snowballEdge
get-secret-access-key
commands, you can get the credentials of the admin
user of your AWS account on Snowball Edge. You can use these credentials to
create AWS Identity and Access Management (IAM users) and roles, and to authenticate your requests when
using the AWS CLI or with an AWS SDK. These credentials are only associated with an
individual job for Snowball Edge, and you can use them only on the device or
cluster of devices. The device or devices don't have any IAM permissions in the
AWS Cloud.
Note
If you're using the AWS CLI with the Snowball Edge, you must use these credentials when you configure the CLI. For information about configuring credentials for the AWS CLI, see Configuring the AWS CLI in the AWS Command Line Interface User Guide.
Usage (configured Snowball Edge client)
snowballEdge list-access-keys
Example Output
{ "AccessKeyIds" : [ "AKIAIOSFODNN7EXAMPLE" ] }
Usage (configured Snowball Edge client)

Starting a service on a Snow Family device
Snowball Edge devices support multiple services. These
include compute instances, the Network File System (NFS) interface, Snow Device Management, and AWS IoT Greengrass. The Amazon S3 adapter service, Amazon EC2, AWS STS, and IAM are started by
default and can't be stopped or restarted. However,
the NFS interface, Snow Device Management, and AWS IoT Greengrass can be started by using its service ID with the start-service
command. To get the service ID for each service, you can use the list-services
command.
Before you run this command, create a single virtual network interface to bind to the service that you're starting. For more information, see Creating a Virtual Network Interface on a Snow Family device.
snowballEdge start-service --profile

--service-idservice_id
--virtual-network-interface-arnsvirtual-network-interface-arn
Example output of start-service
command
Starting the AWS service on your Snowball Edge. You can determine the status of the AWS service using the describe-service command.
Stopping a service on a Snow Family device
To stop a service running on a Snow Family device, you can use the
stop-service
command.
The Amazon S3 adapter, Amazon EC2, AWS STS, and IAM services cannot be stopped.
Warning
Data loss can occur if the Network File System (NFS) service is stopped before remaining buffered data is written to the device. For more information on using the NFS service, see Managing the NFS interface on Snow Family devices.
Note
Stopping the Amazon S3 compatible storage on Snow Family devices service disables access to the data stored in your S3 buckets on the device or cluster. Access is restored when the Amazon S3 compatible storage on Snow Family devices is started again. For devices enabled with Amazon S3 compatible storage on Snow Family devices, it is recommended to start the service after the Snowball Edge device is powered up. See Setting up Snowball Edge in this guide.

Viewing and downloading logs from Snow Family devices
When you transfer data between your on-premises data center and a Snow Family device, logs are automatically generated. If you encounter unexpected errors during data transfer to the device, you can use the following commands to save a copy of the logs to your local server.
There are three commands related to logs:
-
list-logs
– Returns a list of logs in JSON format. This list reports the size of the logs in bytes, the ARN for the logs, the service ID for the logs, and the type of logs.Usage
snowballEdge list-logs --profile
profile-name
Example output of the
list-logs
command{ "Logs" : [ { "LogArn" : "arn:aws:snowball-device:::log/s3-storage-JIEXAMPLE2f-1234-4953-a7c4-dfEXAMPLE709", "LogType" : "SUPPORT", "ServiceId" : "s3", "EstimatedSizeBytes" : 53132614 }, { "LogArn" : "arn:aws:snowball-device:::log/fileinterface-JIDEXAMPLEf-1234-4953-a7c4-dfEXAMPLE709", "LogType" : "CUSTOMER", "ServiceId" : "fileinterface", "EstimatedSizeBytes" : 4446 }] }

that you delete these logs once you're done with them.
Viewing status of a Snow Family device
You can determine the status and general health of Snow Family devices
with the describe-device
command.
snowballEdge describe-device --profile
profile-name
Example output of describe-device
command
{ "DeviceId": "JID-EXAMPLE12345-123-456-7-890", "UnlockStatus": { "State": "UNLOCKED" }, "ActiveNetworkInterface": { "IpAddress": "192.0.2.0" }, "PhysicalNetworkInterfaces": [ { "PhysicalNetworkInterfaceId": "s.ni-EXAMPLEd9ecbf03e3", "PhysicalConnectorType": "RJ45", "IpAddressAssignment": "STATIC", "IpAddress": "0.0.0.0", "Netmask": "0.0.0.0", "DefaultGateway": "192.0.2.1", "MacAddress": "EX:AM:PL:E0:12:34" }, { "PhysicalNetworkInterfaceId": "s.ni-EXAMPLE4c3840068f", "PhysicalConnectorType": "QSFP", "IpAddressAssignment": "STATIC", "IpAddress": "0.0.0.0", "Netmask": "0.0.0.0", "DefaultGateway": "192.0.2.2", "MacAddress": "EX:AM:PL:E0:56:78" }, { "PhysicalNetworkInterfaceId": "s.ni-EXAMPLE0a3a6499fd", "PhysicalConnectorType": "SFP_PLUS", "IpAddressAssignment": "DHCP", "IpAddress": "192.168.1.231", "Netmask": "255.255.255.0", "DefaultGateway": "192.0.2.3", "MacAddress": "EX:AM:PL:E0:90:12" } ] }
Vieiwing status of services running on Snow Family devices
You can determine the status and general health of the services running on
Snowball Edge devices with the describe-service
command. You can
first run the list-services
command to see what services are
running.
-
list-services
Usage
snowballEdge list-services --profile
profile-name
Example output of
list-services
command{ "ServiceIds" : [ "greengrass", "fileinterface", "s3", "ec2", "s3-snow" ] }
-
describe-service
This command returns a status value for a service. It also includes state information that might be helpful in resolving issues you encounter with the service. Those states are as follows.
-
ACTIVE
– The service is running and available for use. -
ACTIVATING
– The service is starting up, but it is not yet available for use. -
DEACTIVATING
– The service is in the process of shutting down. -
DEGRADED
– For Amazon S3 compatible storage on Snow Family devices, this status indicates one or more disks or devices in cluster is down. The Amazon S3 compatible storage on Snow Family devices service is running uninterrupted, but you should recover or replace the affected device before the cluster quorum is lost to minimize the risk of lost data. See Clustering overview in this guide. -
INACTIVE
– The service is not running and is not available for use.

-
Viewing status of features of Snow Family devices
To list the status of features available on a Snow Family device use
the describe-features
command.
RemoteManagementState
indicates the status of Snow Device Management and returns one
of the following states:
INSTALLED_ONLY
– The feature is installed but not enabled.INSTALLED_AUTOSTART
– The feature is enabled and the device will attempt to connect to its AWS Region when it is powered on.NOT_INSTALLED
– The device does not support the feature or was already in the field before its launch.
Usage
snowballEdge describe-features --profile
profile-name
Example output of describe-features
command
{ "RemoteManagementState" : String }
Setting time servers for Snow Family devices
You can use Snowball Edge Client commands to view the current Network Time Protocol (NTP) configuration and choose a server or peer to provide time. You can use the Snowball Edge Client commands when the device is in both locked and unlocked states.
It is your responsibility to provide a secure NTP time server. To set which NTP time
servers the device connects to, use the update-time-servers
command.
Checking time sources of Snow Family devices
To see which NTP time sources the device are currently connected to, use
the describe-time-sources
command.
snowballEdge describe-time-sources --profile
profile-name
Example output of describe-time-sources
command
{ "Sources" : [ { "Address" : "172.31.2.71", "State" : "LOST", "Type" : "PEER", "Stratum" : 10 }, { "Address" : "172.31.3.203", "State" : "LOST", "Type" : "PEER", "Stratum" : 10 }, { "Address" : "172.31.0.178", "State" : "LOST", "Type" : "PEER", "Stratum" : 10 }, { "Address" : "172.31.3.178", "State" : "LOST", "Type" : "PEER", "Stratum" : 10 }, { "Address" : "216.239.35.12", "State" : "CURRENT", "Type" : "SERVER", "Stratum" : 1 } ] }
The describe-time-sources
command returns a list of time source states.
Each time source state contains the Address
, State
, Type
,
and Stratum
fields. Following are the meanings of these fields.
-
Address
– The DNS name / IP address of the time source. -
State
– The current connection status between the device and that time source. There are five possible states:.-
CURRENT
– The time source is currently being used to synchronize time. -
COMBINED
– The time source is combined with the current source. -
EXCLUDED
– The time source is excluded by the combining algorithm. -
LOST
– The connection with the time source has been lost. -
UNACCEPTABLE
– An invalid time source where the combining algorithm has deemed to be either a falseticker or has too much variability.
-
-
Type
– An NTP time source can be either a server or a peer. Servers can be set by theupdate-time-servers
command. Peers can only be other Snowball Edge devices in the cluster and are automatically set up when the cluster is associated. -
Stratum
– This field shows the stratum of the source. Stratum 1 indicates a source with a locally attached reference clock. A source that is synchronized to a stratum 1 source is at stratum 2. A source that is synchronized to a stratum 2 source is at stratum 3, and so on..
An NTP time source can either be a server or a peer. A server can be set by the user
with the update-time-servers
command, whereas a peer could only be other
Snowball Edge devices in the cluster. In the example output, describe-time-sources
is called on a Snowball Edge that is in a cluster of 5. The output contains 4 peers
and 1 server. The peers have a stratum of 10 while the server has a stratum of 1;
therefore, the server is selected to be the current time source.
Updating time servers
Use the update-time-servers
command and the time server address to configure the Snow Family device to use an NTP server or peer for NTP.
snowballEdge update-time-servers --profile
profile-name
time-server-address
Note
The update-time-servers
command will override the previous
NTP time servers settings.
Example output of update-time-servers
command

Getting a QR code to validate Snowball Edge NFC tags
You can use this command to generate a device-specific QR code for use with the AWS Snowball Edge Verification App. For more information about NFC validation, see Validating NFC Tags.
Usage
snowballEdge get-app-qr-code --output-file
~/downloads/snowball-qr-code.png
Example Output
QR code is saved to

Updating MTU size
Use the update-mtu-size
command to modify the size in bytes of the maximum transmission unit (MTU) of a physical interface of a Snow Family device. All virtual network interfaces and direct network interface associated with this physical network interface will be configured with the same MTU size.
Note
The minimum MTU size is 1500 bytes and the maximum size is 9216 bytes.
You can use the describe-device
command to retrieve the physical network interface IDs and current MTU sizes of those interfaces. For more information, see Viewing status of a Snow Family device.
You can use the descibe-direct-network-interface
and describe-virtual-network-interface
commands to retrieve the current MTU sizes of those interfaces.
Usage
snowballEdge update-mtu-size --physical-network-interface-id
