# 通用排查
#### 问题现象
订购BCS实例失败。
#### 排查思路
- [排查项一：账号是否欠费。]
- [排查项二：是否子账号购买，导致的权限不足。]
- [排查项三：实例部署过程中失败，根据具体报错排查。]
 
#### 解决方案
- 排查项一：账号是否欠费。
  1. 登录区块链服务BCS控制台，单击界面上方的"费用中心"，进入费用中心界面。 ![](https://support.huaweicloud.com/bcs_faq/zh-cn_image_0255607772.png "点击放大")
     如"现金余额"为零或小于购买区块链产品时的报价，则会购买失败。
     
  
  2. 在"待支付订单"项下单击"立即支付"，进入我的订单界面，选择待支付目标订单完成支付。 ![](https://support.huaweicloud.com/bcs_faq/zh-cn_image_0255607773.png "点击放大")
     如支付失败并提示余额不足，也会由于费用不足导致购买失败。
     
  
  3. 在"续费资源"项下单击"立即续费"，进入续费管理界面，选择需要续费的目标资源，单击"续费"并支付。
   

- 排查项二：是否子账号购买，导致的权限不足。
  请确认是否子账号购买，并请参考"权限管理"\>"授权IAM用户使用BCS"：[权限管理](https://support.huaweicloud.com/usermanual-bcs/bcs_usermanual_0020.html)添加权限。
  
- 排查项三：实例部署过程中失败，根据具体报错排查。
  1. 登录区块链服务BCS控制台，单击左侧导航栏的"实例管理"。
  
  2. 单击右侧的"操作记录"进入操作记录页面。
  
  3. 单击操作列的"操作详情"。
  
  4. 展开详情后，单击"查看原因"并结合部署进度，根据具体报错信息进行分析。详细请参考[表1]。
