Batch Managing Instances
Function
- Add or remove instances to or from an AS group in batches.
If the instances were manually added to an AS group, they are removed from the AS group but are not deleted.
- Configure instance protection or cancel the configuration for the instances in an AS group in batches.
- A batch operation can be performed on a maximum of 10 instances at a time. After instances are added to an AS group, the number of instances in the AS group cannot be greater than the maximum number of instances. After instances are removed from an AS group, the number of instances in the AS group cannot be less than the minimum number of instances.
- Instances can be added to an AS group only when the AS group is in the INSERVICE state and has no scaling action in progress.
- You can remove instances from an AS group only when no scaling action is in progress.
- To add instances to an AS group, ensure that the AZ of the instances falls within that of the AS group.
- Only instances in INSERVICE state can be removed from an AS group. Instance protection can be enabled or disabled only for INSERVICE instances.
- When the capacity of an AS group is automatically decreased, the instances with instance protection enabled will not be removed from the AS group.
- If the listener bound to the instance to be removed is the same as the listener in the AS group, the listener will be unbound from the instance. If the listener bound to the instance to be removed is different from the listener in the AS group, the binding relationship between the listener and instance will be reserved.
