ECS：「驗證 BMC 可用性」失敗：無效的 BMC 組態，因為 IPMI over LAN 已停用，並同時拒絕 ssh 至 BMC IP 位址的連線

Summary: - [錯誤] 「驗證 BMC 可用性」失敗：無效的 BMC 組態 - 當所有配置正確時，使用者/密碼正確，BMC IP 位址可 ping。 - IPMI 工具在伺服器上本地運行，但當您嘗試通過 LAN/IP 使用它時，它會返回錯誤。 - 此外，當嘗試 ssh BMC IP 位址 （192.168.219.10x） 時，它會拒絕連接。

Symptoms

問題 # 1：進行相容性或執行狀況檢查時，傳回 "[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

在本機使用 IPMI 工具時，它運作正常，但在相同節點上透過 LAN 使用 IPMI 時，它就無法運作。

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

 

問題 # 2 此外，嘗試 ssh BMC IP 位址時，它會拒絕連接。

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

 

Cause

問題 # 1：IPMI Over LAN 已停用。

問題 # 2：停用 SSH。

 

Resolution

 

  1. 若要解決此問題，您必須登入已發出節點的 BMC UI。您可以透過以下 KB 000019917 進行此操作：ECS：如何透過安全遠端服務連線至 BMC/iDRAC 主控台和 VDC UI

  2. 成功登入 BMC UI 後，選取組態> 安全性設定。

  3. 如圖：IPMI over LAN/SSH 停用，您必須勾選方塊，然後按一下儲存以啟用。
    IPMI-SSH

  4. 針對問題 # 1：啟用 IPMI over LAN 後，請執行「service-console run Health_Check --specific-check Validate BMC availability」以確認驗證問題是否已修正，應按如下所示「通過」。

  5. 針對問題 # 2：啟用 SSH 後，SSH 至 BMC IP 位址，應該會如下連線。

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