The handling method depends on the reported possible cause.
Possible cause: insufficient quota
Handling method: Increase the quota or delete unnecessary resources, and then enable the AS group.
Possible cause: The VPC service encounters an exception or resources have been deleted.
Handling method: Wait until the VPC service recovers, or modify parameters of the VPC and subnet in the AS group, and then enable the AS group.
Possible cause: The ELB service encounters an exception or resources have been deleted.
Handling method: Wait until the ELB service recovers, or modify load balance parameters in the AS group, and then enable the AS group.
Possible cause: If classical load balancer is used by an AS group, instances added to the AS group are automatically added to the ELB listener. A maximum of 300 backend ECSs can be added to an ELB listener.
Handling method: Remove the backend ECSs that are both not required and not in the AS group from the listener. Then enable the AS group.
Possible cause: Resources have been deleted.
Handling method: Change the AS configuration for the AS group and then enable the AS group.
Possible cause: Private IP addresses in the subnet used by the AS group have been used up.
Handling method: Modify the subnet information and enable the AS group.
Possible cause: This type of ECSs has been sold out or is not supported in the AZ selected for the AS group. The ECS flavor selected in the AS configuration is sold out.
Handling method: Change the AS configuration for the AS group and then enable the AS group. If there is no instance in the AS group, you can also change the AZ for the AS group and then enable the AS group.
Possible cause: The ECS type in the AS configuration does not match the disk type, leading to the ECS creation failure.
Handling method: Change the AS configuration for the AS group and then enable the AS group.
Possible cause: The ECS type in the AS configuration does not match the image, leading to the ECS creation failure.
Handling method: Change the AS configuration for the AS group and then enable the AS group.
Possible cause: Storage resources of this type have been sold out or are not supported in the AZ selected for the AS group. Storage resources of this type refer to the system and data disk types selected for the AS configuration.
Handling method: Change the AS configuration for the AS group and then enable the AS group. If there is no instance in the AS group, you can also change the AZ for the AS group and then enable the AS group.
Possible cause: An error has occurred in the AS service, peripheral service, or network.
Handling method: Try again later or contact technical support.
Handling method: Change specifications by creating an AS configuration as prompted by the error message and use this AS configuration for the AS group. Then enable the AS group.
Handling method: Create an AS configuration as prompted by the error message and use this AS configuration for the AS group. Then enable the AS group.
