¶
About DescribeVolumeStatus¶
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 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 EBS 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 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.)
The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.
Method Signature¶
IMPORTING¶
Optional arguments:¶
IV_MAXRESULTS
TYPE /AWS1/EC2INTEGER
/AWS1/EC2INTEGER
¶
The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination.
IV_NEXTTOKEN
TYPE /AWS1/EC2STRING
/AWS1/EC2STRING
¶
The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.
IT_VOLUMEIDS
TYPE /AWS1/CL_EC2VOLIDSTRINGLIST_W=>TT_VOLUMEIDSTRINGLIST
TT_VOLUMEIDSTRINGLIST
¶
The IDs of the volumes.
Default: Describes all your volumes.
IV_DRYRUN
TYPE /AWS1/EC2BOOLEAN
/AWS1/EC2BOOLEAN
¶
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 isUnauthorizedOperation
.
