在oracle11GR2圖形介面進行安裝檢查的時候提示“Node connectivity check failed”,如所示:




網上說出現這個問題的原因主要有兩個:

1./etc/hosts沒有配好
2.Linux中未關閉Firewall

但是我的防火牆是關閉的,hosts檔案也確定配置好了。

通過runcluvfy工具來檢查:

grid@node74:/home/software/linux_11gR2/grid> ./runcluvfy.sh stage -post hwos -n node74,node76 -verbose

Performing post-checks for hardware and operating system setup

Interfaces found on subnet "10.10.10.0" that are likely candidates for a private interconnect are:
node76 eth1:10.10.10.2
node74 eth1:10.10.10.1

Result: Node connectivity check failed

Checking for multiple users with UID value 0
Result: Check for multiple users with UID value 0 passed 

Post-check for hardware and operating system setup was unsuccessful on all the nodes. 

原來是因為兩個節點有一對網卡配置了通網段的IP地址,但是實際上兩個網卡並沒有連通,造成了node connectivity檢查失敗。

  node74:20.20.20.1               node76:20.20.20.2               failed   


這樣解決辦法就有了,要麼就是把兩個網卡連通,要麼就是修改為不同的網段,或者乾脆直接停用這兩塊網卡。

我這邊停用這兩塊網卡後,重新執行安裝檢查通過。
