# 绑定磁盘

您可以在创建实例时或创建后添加存储。

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

* <mark style="color:blue;">最多可以绑定 1 块磁盘来扩展实例存储。</mark>
* <mark style="color:blue;">只能绑定与实例处于同一可用区的磁盘。</mark>
  {% endhint %}

## 操作步骤

1. 通过以下任一方式进入 **添加存储**：

   * **弹性计算实例** > **操作** > **实例设置** > **添加存储**
   * **实例详情** > **信息** > **存储** > **添加存储**
   * **磁盘** > **操作** > **绑定**

2. 选择所需的磁盘并点击 **确认** 进行绑定。如果没有所需磁盘，点击 **新建磁盘** 来创建新的磁盘。\
   详细步骤请参阅 [**创建磁盘**](/welcome/cn/elastic-compute/get-started/manage-storage/create-a-disk.md)。

## 下一步操作

绑定后，磁盘默认处于离线状态。请访问您的实例并初始化磁盘。详细步骤请参阅 [**初始化磁盘**](/welcome/cn/elastic-compute/get-started/manage-storage/initialize-a-disk.md)。
