AttachDisks

1. API Description

This API is used to attach disks to instance.

Note

• A maximum of 10 disks can be attached to an instance in one request.

• Quantity of attached disks cannot exceed available disk numbers of an instance, that is usually 15 disks.

• The disk and the instance to which you want to attach the disk reside in the same availability zone.

• You can only attach disks to the available instance. Please note that status of DEPLOYING or PENDING is not available.

• Disks must be detachable.

• This API is an async API. A request ID is returned after the creation request is sent. However, it does not mean the operation has been completed. You can use DescribeDisks to query the status of the disk. If the status changes from AVAILABLE to IN_USE, it means that the disk is attached successfully.
