Expanding 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. The expansion API uses asynchronous notification, and you need to confirm the expansion results on the VM. This API call exists for compatibility reasons only and is not meant to be used.

Constraints

If the status of the to-be-expanded disk is in-use, the restrictions are as follows:

  • A shared disk cannot be expanded, which means that the value of multiattach must be false.

  • The status of the server to which the disk attached must be ACTIVE, PAUSED, SUSPENDED, or SHUTOFF.
