DescribeDisks

POST

Query the list of cloud disks.

Wire call

Converge Cloud is RPC over HTTP. There is one path — / — and the action travels in the X-TC-Action header. The /cbs/DescribeDisks path used in the OpenAPI document is a documentation convenience so each action is addressable; it is not a route on the server.

Request parameters

FieldTypeRequiredDescription
DiskIdsstring[]—Query by one or more cloud disk IDs, such as `disk-11112222`. For the format of this parameter, please see the ids.N section of the API Introduction. This parameter does not support specifying both `DiskIds` and `Filters`.
FiltersFilter[]—Filters. You cannot specify `DiskIds` and `Filters` at the same time. disk-usage - Array of String - Optional - Filters by cloud disk type. (SYSTEM_DISK: system disk | DATA_DISK: data disk) disk-charge-type - Array of String - Optional - Filters by cloud disk billing method. (POSTPAID_BY_HOUR: pay-as-you-go) portable - Array of String- Optional - Filters by whether the cloud disk is elastic or …
Offsetinteger—Offset. Default is 0. For more information on `Offset`, please see relevant sections in API Introduction.
Limitinteger—Number of results to be returned. Default is 20. Maximum is 100. For more information on `Limit`, please see relevant sections in API Introduction.
Orderstring—Outputs the ordering of the cloud disk list. Value range: ASC: Ascending order DESC: Descending order.
OrderFieldstring—The field by which the cloud disk list is sorted. Value range: CREATE_TIME: sorted by the creation time of cloud disks DEADLINE: sorted by the expiration time of cloud disks By default, the cloud disk list is sorted by the creation time of cloud disks.
ReturnBindAutoSnapshotPolicyboolean—Whether the ID of the periodic snapshot policy bound to the cloud disk needs to be returned in the cloud disk details. TRUE: return; FALSE: do not return.

Response

Fields are returned inside the Response envelope. Converge Cloud answers HTTP 200 for errors as well as successes, so read Response.Error rather than the status code — and test for the presence of that object, because Code is occasionally the empty string.

FieldTypeDescription
TotalCountintegerThe quantity of cloud disks meeting the conditions.
DiskSetDisk[]List of cloud disk details.
RequestIdstringThe unique request ID, which is returned for each request. RequestId is required for locating a problem.

Behaviour

DeleteWithInstance defaults to true for a system disk, which is therefore deleted with its instance.
