You can enable an AS group to automatically increase or decrease instances.
After an AS group is enabled, its status changes to Enabled. AS monitors the AS policy and triggers a scaling action for AS groups only in Enabled state. After an AS group is enabled, AS triggers a scaling action to automatically add or remove instances if the number of instances in the AS group is different from the expected number of instances.
An AS group can be enabled only when its status is Disabled. Only if the status of an AS group is Abnormal, you can select Forcibly Enable from the More drop-down list to enable it.
After you add an AS configuration to an AS group, the AS group is automatically enabled.
