Use StartPairDrill to start a disaster recovery drill for a replication pair - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service: Central de Documentação do Alibaba Cloud

Starts a disaster recovery drill to ensure the continued replication and clone the data from the last recovery point of the secondary disk to a new disk. This helps you test the completeness and correctness of applications that are deployed on the disaster recovery site on a regular basis.

Operation description

After the disaster recovery drill is complete on the secondary disk, a pay-as-you-go drill disk that has the same capacity and category as the secondary disk is created in the zone where the secondary disk resides. The drill disk contains last-recovery-point data that can be used to test the completeness and correctness of applications.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the secondary disk in the replication pair. You can call the DescribeDiskReplicaPairs operation to query the region in which the secondary disk of the replication pair resides. Note You must enable the disaster recovery drill feature in the region in which the secondary site resides.	cn-hangzhou
PairId	string	Yes	The ID of the replication pair. You can call the DescribeDiskReplicaPairs operation to query a list of replication pairs, including replication pair IDs.	pair-xxxx
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence.	123e4567-e89b-12d3-a456-42665544****
