# 更新磁盘信息 - UpdateDiskInfo
#### 功能介绍
更新服务器的磁盘信息，此接口会把服务器原有磁盘信息清空，然后更新成新磁盘信息。
接口仅在"待设置目的端"才能生效，开始迁移后更改磁盘信息不生效。
#### 调用方法
请参见[如何调用API](https://support.huaweicloud.com/api-sms/sms_api_0007.html)。
#### 授权信息
账号具备所有API的调用权限，如果使用账号下的IAM用户调用当前API，该IAM用户需具备调用API所需的权限。
- 如果使用角色与策略授权，具体权限要求请参见[权限和授权项](https://support.huaweicloud.com/api-sms/sms_api_8001.html)。
- 如果使用身份策略授权，需具备如下身份策略权限。
