Creating a Disk Transfer

Function

This API is used to create a disk transfer. After the transfer has been created, a transfer ID and an authentication key are returned.

After a disk transfer is created, the disk status changes from available to awaiting-transfer. Once the disk transfer is accepted, the disk status changes to available again.

Constraints

A disk transfer can be created only when the disk status is available. The detailed constraints are as follows:

• EVS disks with backups and snapshots available cannot be transferred.
• EVS disks associated with backup policies cannot be transferred.
• EVS disks used as system disks cannot be transferred.

If the disk transfer is created using one of the unsupported disks, error code 400 will be returned.
