Symptoms

问题#1：执行合规性或运行状况检查时，它会返回 "[ERROR] 'Validate BMC availability' failed: Invalid BMC configuration on some/all nodes."

On node with IP 169.254.1.1 and FQDN xxxxx-node1.yyyyy.com, Can't connect to BMC IP 192.168.219.101
On node with IP 169.254.1.3 and FQDN xxxxx-node3.yyyyy.com, Can't connect to BMC IP 192.168.219.103
On node with IP 169.254.1.4 and FQDN xxxxx-node4.yyyyy.com, Can't connect to BMC IP 192.168.219.104
On node with IP 169.254.1.5 and FQDN xxxxx-node5.yyyyy.com, Can't connect to BMC IP 192.168.219.105

在本地使用 IPMI 工具时，它可以正常工作，但是当为同一节点使用 IPMI over LAN 时，它不起作用。

admin@xxxxx-node1:~> sudo  ipmitool chassis power status
Chassis Power is on

admin@xxxxx-node1:~> ipmitool -I lanplus -H 192.168.219.101 -U root -P passwd power status
Error: Unable to establish IPMI v2 / RMCP+ session

 

问题#2 此外，当尝试通过 ssh 连接 BMC IP 地址时，它会拒绝连接。

admin@xxxxx-node1~> ssh root@192.168.219.101
ssh: connect to host 192.168.219.101 port 22: Connection refused

 

Cause

问题#1：已禁用 IPMI over LAN。

问题#2：SSH 处于禁用状态。

 

Resolution

 

  1. 要解决此问题，您必须登录到已颁发节点的 BMC UI。您可以通过以下知识库文章000019917来执行此作：ECS：如何通过 Secure Remote Services 连接到 BMC/iDRAC 控制台和 VDC UI

  2. 成功登录到 BMC UI 后，选择配置> 安全设置。

  3. 如图所示，IPMI over LAN/SSH 已禁用，您必须选中复选框，然后单击 Save以启用。
    IPMI-SSH

  4. 对于问题 #1：启用 LAN 上 IPMI 后，运行”service-console run Health_Check --specific-check Validate BMC availability“以确认验证问题是否已解决，它应通过，如下所示。

    Service console version: 8.3.0.0-22532.3ce6e27b27

  5. 对于问题 # 2：启用 SSH 后，通过 ssh 连接到 BMC IP 地址，它应该连接如下。

    admin@xxxxx-node1:~> ssh root@192.168.219.101
