/**
* Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#describeVolumeStatus(DescribeVolumeStatusRequest) DescribeVolumeStatus operation}.
* <p>
* Describes the status of the specified volumes. Volume status provides
* the result of the checks performed on your volumes to determine events
* that can impair the performance of your volumes. The performance of a
* volume can be affected if an issue occurs on the volume's underlying
* host. If the volume's underlying host experiences a power outage or
* system issue, after the system is restored, there could be data
* inconsistencies on the volume. Volume events notify you if this
* occurs. Volume actions notify you if any action needs to be taken in
* response to the event.
* </p>
* <p>
* The <code>DescribeVolumeStatus</code> operation provides the following
* information about the specified volumes:
* </p>
* <p>
* <i>Status</i> : Reflects the current status of the volume. The
* possible values are <code>ok</code> ,
* <code>impaired</code> ,
* <code>warning</code> , or
* <code>insufficient-data</code> . If all checks pass, the overall
* status of the volume is <code>ok</code> . If the check fails, the
* overall status is <code>impaired</code> . If the status is
* <code>insufficient-data</code> , then the checks may still be taking
* place on your volume at the time. We recommend that you retry the
* request. For more information on volume status, see
* <a href="http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-volume-status.html"> Monitoring the Status of Your Volumes </a>
* .
* </p>
* <p>
* <i>Events</i> : Reflect the cause of a volume status and may require
* you to take action. For example, if your volume returns an
* <code>impaired</code> status, then the volume event might be
* <code>potential-data-inconsistency</code> . This means that your
* volume has been affected by an issue with the underlying host, has all
* I/O operations disabled, and may have inconsistent data.
* </p>
* <p>
* <i>Actions</i> : Reflect the actions you may have to take in response
* to an event. For example, if the status of the volume is
* <code>impaired</code> and the volume event shows
* <code>potential-data-inconsistency</code> , then the action shows
* <code>enable-volume-io</code> . This means that you may want to enable
* the I/O operations for the volume by calling the EnableVolumeIO action
* and then check the volume for data consistency.
* </p>
* <p>
* <b>NOTE:</b> Volume status is based on the volume status checks, and
* does not reflect the volume state. Therefore, volume status does not
* indicate volumes in the error state (for example, when a volume is
* incapable of accepting I/O.)
* </p>
