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.
The describe_volume_status operation
provides the following information about the specified volumes:
Status: Reflects the current status of the volume. The possible values
are ok, impaired , warning, or insufficient-data. 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 insufficient-data, 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 Monitoring 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 shows potential-data-inconsistency, then the action shows
enable-volume-io. This means that you may want to enable the I/O
operations for the volume by calling the
enable_volume_io 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 error state (for example, when a volume is incapable of accepting
I/O.)

The filters.
action.code - The action code for the event (for example,
enable-volume-io).
action.description - A description of the action.
action.event-id - The event ID associated with the action.
availability-zone - The Availability Zone of the instance.
event.description - A description of the event.
event.event-id - The event ID.
event.event-type - The event type (for io-enabled: passed |
failed; for io-performance: io-performance:degraded |
io-performance:severely-degraded | io-performance:stalled).
event.not-after - The latest end time for the event.
event.not-before - The earliest start time for the event.
volume-status.details-name - The cause for volume-status.status
(io-enabled | io-performance).
volume-status.details-status - The status of
volume-status.details-name (for io-enabled: passed | failed;
for io-performance: normal | degraded | severely-degraded |
stalled).
volume-status.status - The status of the volume (ok | impaired
| warning | insufficient-data).
The maximum number of volume results returned by
describe_volume_status in paginated
output. When this parameter is used, the request only returns
MaxResults results in a single page along with a NextToken response
element. The remaining results of the initial request can be seen by
sending another request with the returned NextToken value. This value
can be between 5 and 1,000; if MaxResults is given a value larger than
1,000, only 1,000 results are returned. If this parameter is not used,
then describe_volume_status returns all
results. You cannot specify this parameter and the volume IDs parameter
in the same request.
The NextToken value to include in a future
describe_volume_status request. When the
results of the request exceed MaxResults, this value can be used to
retrieve the next page of results. This value is null when there are
no more results to return.
The IDs of the volumes.
Default: Describes all your volumes.
Checks whether you have the required permissions for the action, without
actually making the request, and provides an error response. If you have
the required permissions, the error response is DryRunOperation.
Otherwise, it is UnauthorizedOperation.
