-- 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.
