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.
DescribeVolumeStatus operation provides the following information
about the specified volumes:
Status: Reflects the current status of the volume. The possible values are
If all checks pass, the overall status of the volume is
ok. If the check
fails, the overall status is
impaired. If the status is
then the checks may still be taking place on your volume at the time. We recommend
that you retry the request. For more information about volume status, see Monitoring
the Status of Your Volumes in the Amazon Elastic Compute Cloud User Guide.
Events: Reflect the cause of a volume status and may require you to take action.
For example, if your volume returns an
impaired status, then the volume
event might be
potential-data-inconsistency. 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.
Actions: Reflect the actions you may have to take in response to an event.
For example, if the status of the volume is
impaired and the volume event
potential-data-inconsistency, then the action shows
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.
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
state (for example, when a volume is incapable of accepting I/O.)
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginDescribeVolumeStatus and EndDescribeVolumeStatus.
