Expanding the Capacity of an EVS Disk (Deprecated)

Function

This API is used to expand the capacity of an EVS disk.

  • If the status of the to-be-expanded disk is available, there are no restrictions.
  • If the status of the to-be-expanded disk is in-use, the restrictions are as follows:
    • The shared disk cannot be expanded, that is, the value of parameter multiattach must be false.
    • The status of the ECS to which the disk attached must be ACTIVE, PAUSED, SUSPENDED, or SHUTOFF.

This API call exists for compatibility reasons only and is not meant to be used.
