attach-volume

Description

Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.

Encrypted EBS volumes must be attached to instances that support Amazon EBS encryption. For more information, see Amazon EBS encryption in the Amazon Elastic Compute Cloud User Guide .

After you attach an EBS volume, you must make it available. For more information, see Make an EBS volume available for use .

If a volume has an Amazon Web Services Marketplace product code:

• The volume can be attached only to a stopped instance.

• Amazon Web Services Marketplace product codes are copied from the volume to the instance.

• You must be subscribed to the product.

• The instance type and operating system of the instance must support the product. For example, you can’t detach a volume from a Windows instance and attach it to a Linux instance.

For more information, see Attach an Amazon EBS volume to an instance in the Amazon Elastic Compute Cloud User Guide .

Synopsis

  attach-volume
--device <value>
--instance-id <value>
--volume-id <value>
[--dry-run | --no-dry-run]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--device (string)

The device name (for example, /dev/sdh or xvdh ).

--instance-id (string)

The ID of the instance.

--volume-id (string)

The ID of the EBS volume. The volume and instance must be within the same Availability Zone.

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To attach a volume to an instance

This example command attaches a volume (vol-1234567890abcdef0) to an instance (i-01474ef662b89480) as /dev/sdf.

Command:

aws ec2 attach-volume --volume-id vol-1234567890abcdef0 --instance-id i-01474ef662b89480 --device /dev/sdf

Output:

{
    "AttachTime": "YYYY-MM-DDTHH:MM:SS.000Z",
    "InstanceId": "i-01474ef662b89480",
    "VolumeId": "vol-1234567890abcdef0",
    "State": "attaching",
    "Device": "/dev/sdf"
}

Output

AttachTime -> (timestamp)

The time stamp when the attachment initiated.

Device -> (string)

The device name.

InstanceId -> (string)

The ID of the instance.

State -> (string)

The attachment state of the volume.

VolumeId -> (string)

The ID of the volume.

DeleteOnTermination -> (boolean)

Indicates whether the EBS volume is deleted on instance termination.
