Attaching EVS Disks to a FlexusX Instance

Scenarios

If the disks of a FlexusX instance cannot meet service requirements, for example, there is not enough disk space, you can attach more available disks to the FlexusX instance.

Constraints

• EVS disks can only be attached to FlexusX instances in the same region.
• Non-shared disks can be only attached when they are in the Available state.

  Shared disks can be attached when they are in the In-use or Available state.

• A FlexusX instance must be in the Running or Stopped state before EVS disks can be attached to it.
• A frozen EVS disk cannot be attached to a FlexusX instance.
• A SCSI EVS disk cannot be attached as the system disk to a FlexusX instance.
• A detached system disk can be used as a data disk for any FlexusX instances, but can only be used as a system disk for the FlexusX instance where it was attached before.
• A detached data disk that is purchased together with a FlexusX instance can only be used as a data disk for this instance.
