-- | 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 enabling I/O access and then
-- checking the data consistency on your volume. You can change the default
-- behavior to resume I/O operations. We recommend that you change this only
-- for boot volumes or for volumes that are stateless or disposable.
