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 might still be taking place on your volume at the time. We recommend
that you retry the request. For more information about volume status, see Monitor
the status of your volumes in the Amazon Elastic Compute Cloud User Guide.
Events: Reflect the cause of a volume status and might 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 might have inconsistent data.
Actions: Reflect the actions you might 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.)
For .NET Core this operation is only available in asynchronous form. Please refer to DescribeVolumeStatusAsync.
