Expanding Capacity of an EVS Disk
Function
This API is used to expand the capacity of a pay-per-use or yearly/monthly disk.
Constraints
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, 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.
