Start a disaster recovery drill for a replication pair-consistent group by calling StartReplicaGroupDrill - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service: Central de Documentação do Alibaba Cloud

Starts a disaster recovery drill in a replication pair-consistent group to ensure the continued replication and restores data from the latest recovery point of secondary disks to new disks. This helps 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 secondary disks, a pay-as-you-go drill disk is created in the zone where the secondary disk of each replication pair resides. The latest-recovery-point data is restored to the drill disks 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 ID of the region where the secondary site in the replication pair-consistent group is located. You can call the DescribeDiskReplicaGroups operation to query the region where the secondary site in the replication pair-consistent group is located. Note You must enable the disaster recovery drill feature in the region in which the secondary site resides.	cn-hangzhou
GroupId	string	Yes	The ID of the replication pair-consistent group ID. You can call the DescribeDiskReplicaGroups operation the most recent list of async replication pair-consistent groups, including group IDs.	pg-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****
