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 DescribeVolumeStatus
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 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 Monitoring the Status of YourVolumes.
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
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 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 error
state (for example, when a volume is incapable of accepting I/O.)
