# DetachDisks

## 1. API Description

This API (DetachDisks) is used to detach one or more disks from an instance.

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

* <mark style="color:blue;">Disks to be detached should be attached to the same instance.</mark> <mark style="color:blue;">If any of the disks is undetachable, the operation will not be performed.</mark>
* <mark style="color:blue;">Only operations on disks with the status of</mark> <mark style="color:blue;">`IN_USE`</mark> <mark style="color:blue;">are supported.</mark>
* <mark style="color:blue;">Only operations on disks that are detachable (</mark><mark style="color:blue;">`portable`</mark> <mark style="color:blue;">=</mark> <mark style="color:blue;">`true`</mark><mark style="color:blue;">) are supported.</mark>
* <mark style="color:blue;">Only operations on data disks are supported.</mark>
* <mark style="color:blue;">A maximum of 10 disks can be detached from an instance in one request.</mark>
* <mark style="color:blue;">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</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 the status changes from</mark> <mark style="color:blue;">`IN_USE`</mark> <mark style="color:blue;">to</mark> <mark style="color:blue;">`AVAILABLE`</mark><mark style="color:blue;">, it means that the disk is detached successfully.</mark>
