What Are the Requirements for Attaching an EVS Disk to an ECS?

  • The EVS disk and the target ECS must be located in the same AZ.
  • The target ECS must be in Running or Stopped state.
  • The EVS disk must not be frozen.
  • For yearly/monthly ECSs:

    If you detach the system disk that you purchased when creating an ECS and want to continue using it as a system disk, you can only attach it to the original ECS. If you want to use it as a data disk, you can attach it to any ECS.

    If you detach the non-shared data disk that you purchased when creating an ECS and want to attach it again, you can only attach it to the original ECS as a data disk.
