attach_volume

Operation

attach_volume async

attach_volume(input: AttachVolumeInput, plugins: list[Plugin] | None = None) -> AttachVolumeOutput

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

Note

The maximum number of Amazon EBS volumes that you can attach to an instance depends on the instance type. If you exceed the volume attachment limit for an instance type, the attachment request fails with the AttachmentLimitExceeded error. For more information, see Instance volume limits.

After you attach an EBS volume, you must make it available for use. 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 EBS User Guide.

Parameters:

Name Type Description Default
input AttachVolumeInput

An instance of AttachVolumeInput.

plugins list[Plugin] | None

A list of callables that modify the configuration dynamically. Changes made by these plugins only apply for the duration of the operation execution and will not affect any other operation invocations.
