Release: AWS SDK for .NET 1.4.5

The new Amazon Elastic Compute Cloud API version 2012-03-01 introduces four new API actions to support volume status checks: DescribeVolumeStatus, DescribeVolumeAttribute, EnableVolumeIO, and ModifyVolumeAttribute.
Volume status checks provide information about the I/O (read/write) capability of your Amazon Elastic Block Store (Amazon EBS) volume. The status check lets you know when an EBS volume's data is potentially inconsistent.

The following sample first retrieves the status of a specific volume and then retrieves the status information for all volumes associated with the account:

DescribeVolumeStatusResult result;

// retrieve status for a specific volume, by volume id
result = client.DescribeVolumeStatus(new DescribeVolumeStatusRequest
{
    VolumeId = new List { volumeId }
}).DescribeVolumeStatusResult;
foreach (VolumeStatus status in result.VolumeStatus)
    Console.WriteLine(status.VolumeId + " " + status.VolumeStatusInfo.Status);

// retrieve status for every volume and page through the results
DescribeVolumeStatusRequest request = new DescribeVolumeStatusRequest();
do
{
    result = client.DescribeVolumeStatus(request).DescribeVolumeStatusResult;                
    request.NextToken = result.NextToken;

    foreach (VolumeStatus status in result.VolumeStatus)
        Console.WriteLine(status.VolumeId + " " + status.VolumeStatusInfo.Status);
} while (!string.IsNullOrEmpty(result.NextToken));
