    Elastic High Performance Computing:AttachSharedStorages

    最終更新日:Jan 14, 2026

    Attaches shared storage to an Elastic High Performance Computing (E-HPC) cluster.

    Operation description

    Usage notes

    When you call this operation, take note of the following items:

    • The file system that you want to attach must be created in advance in the same virtual private cloud (VPC) as the destination cluster. For more information, see Create a file system and Manage mount targets.
    • E-HPC clusters support Apsara File Storage NAS file systems.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • For mandatory resource types, indicate with a prefix of * .
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
