Modifying QoS of an EVS Disk
Function
This API is used to change the IOPS or throughput of an EVS disk.
Constraints
The disk must be in the available or in-use state.
For a General Purpose SSD V2 disk, both the IOPS and throughput can be changed. For an Extreme SSD V2 disk, only the IOPS can be changed. This API is not supported for other types of EVS disks.
Calling Method
For details, see Calling APIs.
