Attaching Existing 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 to allow EVS disks to 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.
For details about attaching disks, see Attaching a Non-Shared Disk and Attaching a Shared Disk.
Prerequisites
- EVS disks are available.
For instructions about how to purchase an EVS disk, see Purchasing an EVS Disk.
