ECS Statuses
|
|
============
|
|
|
|
An ECS can be in one of the following statuses specified in ECS APIs:
|
|
|
|
- **status**: specifies an ECS status, which is generated by **OS-EXT-STS:vm_state** and **OS-EXT-STS:task_state**.
|
|
- **OS-EXT-STS:vm_state**: indicates that the ECS is in a stable state after an operation is performed. This is an extended attribute.
|
|
- **OS-EXT-STS:task_state**: indicates an intermediate status in which the ECS is processing an operation performed on it. This is an extended attribute.
