AttachVscToFilesystems - Cloud Parallel File Storage - Alibaba Cloud Documentation Center

Associates VSC devices with file systems.

Operation description

Only CPFS for Lingjun supports this feature.
Batch execution is supported. In batch execution, only one VscId can be associated with multiple FileSystemIds. This means the ResourceIds.VscId values must be identical.

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
ResourceIds	array<object>	Yes	The IDs of the file systems and virtual storage channels (VSCs). You can specify up to 10 IDs per batch. Pass this parameter in the flat format, such as ResourceIds.1.FileSystemId=bmcpfs-xxx&ResourceIds.1.VscId=vsc-xxx. JSON arrays are not supported.
	object	No	The IDs of the file systems and VSCs. You can specify up to 10 IDs per batch.
FileSystemId	string	No	The ID of the file system.	bmcpfs-290t15yn4uo8lid****
VscId	string	No	The ID of the VSC. You can call the ListVscs operation of Lingjun AI Computing Service (eflo-controller/2022-12-15) to query VSCs. If no VSC is created, you can call the CreateVsc operation to create one.	vsc-8vb864o3ppwfvh****
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can generate the value from your client and ensure that the value is unique across different requests. The client token can only contain ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence. Note If you do not specify this parameter, the system automatically uses the RequestId of the API request as the client token. The RequestId may be different for each API request.	123e4567-e89b-12d3-a456-42665544****
