Otherwise, the attach information in the EVS disk list may be inconsistent with that on the HUAWEI CLOUD ECS. Detach the EVS disks in the reverse order of the attach sequence. For example, if three EVS disks are attached to an ECS and are displayed as /dev/sda, /dev/sdb, and /dev/sdc in the Mount Info column in the EVS disk list, detach these EVS disks in the order of /dev/sdc, /dev/sdb, and /dev/sda.
