{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

* <mark style="color:blue;">If you create a subscription disk, the amount required will be pre-deducted. If the balance is insufficient, the request will fail. If you create a pay-as-you-go disk, please ensure your account balance is sufficient before calling this API.</mark>
* <mark style="color:blue;">This API is an async API. A disk ID list is returned after the creation request is sent. However, it does not mean the creation has been completed. You can use</mark> [<mark style="color:purple;">`DescribeDisks`</mark>](/api-reference/compute/vm/disk/describedisks.md) <mark style="color:blue;">to query the status of the disk. If disk has been queried with the</mark> <mark style="color:blue;">`Available`</mark> <mark style="color:blue;">status,</mark> <mark style="color:blue;">it means that the disk has been created successfully;</mark> <mark style="color:blue;">if disk has been attached to a certain instance while creating, the</mark> <mark style="color:blue;">`IN_USE`</mark> <mark style="color:blue;">status means attaching successfully.</mark>
