What Are the Restrictions on Attaching an EVS Disk to an ECS?

Updated at: Dec 16, 2019 GMT+08:00
  • The EVS disk and the target ECS must be located in the same AZ.
  • The target ECS must be in Running or Stopped state.
  • A frozen EVS disk cannot be attached to an ECS.
  • For yearly/monthly ECSs:

    If you detach the system disk 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 purchased when you create an ECS and want to attach it again, you can only attach it to the original ECS as a data disk.
