症状

xDoctor 报告 BMC （IPMI） 无响应： 
Timestamp = 2019-02-11_083547
Category = IPMI
Source = OS
Severity = WARNING
Message = BMC (IPMI) not Responding on the following nodes
Extra = 169.254.1.3,169.254.1.4,169.254.1.6
运行 xDoctor 时，它会报告上述节点上的 BMC （IPMI） 无响应，以及无响应的 IP 专用 IP 地址列表。

我们可以对 IP 地址执行 ping作，但不能将 IPMI 工具与内部 IP 配合使用。但是，我们可以使用 BMC IP 来使用 IPMI 工具。

原因

禁用 IPMI 时，我们会遇到以下问题：

  • BMC 外部身份验证失败：
# for i in $(seq 1 8); do echo $i;ipmitool -H 192.168.219.10$i -U root -P passwd -I lanplus chassis power status; done 

Expected Output Similar to:

1
Error: Unable to establish IPMI v2 / RMCP+ session
2
Error: Unable to establish IPMI v2 / RMCP+ session
3
Error: Unable to establish IPMI v2 / RMCP+ session
4

  • BMC 在内部响应而不进行身份验证：
# domulti ipmitool chassis power status

Expected Output Similar to:
  
192.168.219.1
========================================
Chassis Power is on
  
192.168.219.2
========================================
Chassis Power is on
  
192.168.219.3
========================================

192.168.219.4

192.168.219.7
========================================

  • 登录到 IPMI 有问题的节点，并检查是否禁用了 LAN 访问：
# sudo ipmitool channel info 1

Expected Output Similar to:
 
Channel 0x1 info:
  Channel Medium Type   : 802.3 LAN
  Channel Protocol Type : IPMB-1.0
  Session Support       : multi-session
  Active Session Count  : 0
  Protocol Vendor ID    : 7154
  Volatile(active) Settings
    Alerting            : enabled
    Per-message Auth    : enabled
    User Level Auth     : enabled
    Access Mode         : disabled
  Non-Volatile Settings
    Alerting            : enabled
    Per-message Auth    : enabled
    User Level Auth     : enabled
    Access Mode         : disabled <-- Lan access DISABLED.

解决方案

如果禁用了 IPMI，请与用户确认是否出于某种原因而禁用它。如果没有，请从用户处获取权限以启用它。
  • 运行以下命令以在同一节点上启用它：
# sudo ipmitool lan set 1 access on
 
Expected Output Similar to:

Set Channel Access for channel 1 was successful.
  • 启用后检查 LAN 访问，使其 应始终启用：
# sudo ipmitool channel info 1

 Expected Output Similar to:

Channel 0x1 info:
  Channel Medium Type   : 802.3 LAN
  Channel Protocol Type : IPMB-1.0
  Session Support       : multi-session
  Active Session Count  : 0
  Protocol Vendor ID    : 7154
  Volatile(active) Settings
    Alerting            : enabled
    Per-message Auth    : enabled
    User Level Auth     : enabled
    Access Mode         : always available
  Non-Volatile Settings
    Alerting            : enabled
    Per-message Auth    : enabled
    User Level Auth     : enabled
    Access Mode         : always available  <-- Always Enabled.
  • 验证所有节点是否都通过 LAN 进行响应：
# for i in $(seq 1 8); do echo $i;ipmitool -H 192.168.219.10$i -U root -P passwd -I lanplus chassis power status; done
