Expanding Capacity of an EVS Disk

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:

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

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