ec2-modify-volume-attribute
Description
Modifies a volume attribute.
By default, all I/O operations for the volume are suspended when the data on the volume is determined to be potentially inconsistent, to prevent undetectable, latent data corruption. The I/O access to the volume can be resumed by first issuing the ec2-enable-volume-io command to enable I/O access and then checking the data consistency on your volume.
You can change the default behavior to resume I/O operations without issuing the
ec2-enable-volume-io command by setting the
auto-enable-io attribute of the volume to true. We
recommend that you change this attribute only for volumes that are stateless or
disposable, or for boot volumes.
The short version of this command is ec2mvolatt.

Deprecated Options
For a limited time, you can still use the private key and X.509 certificate instead of your access key ID and secret access key. However, we recommend that you start using your access key ID (-O, --aws-access-key) and secret access key (-W, --aws-secret-key) now, as the private key (-K, --private-key) and X.509 certificate (-C, --cert) won't be supported after the transition period elapses. For more information, see Tell the Tools Who You Are.
