在oracle11GR2图形界面进行安装检查的时候提示“Node connectivity check failed”,如下图所示:
网上说出现这个问题的原因主要有两个:
1./etc/hosts没有配好
2.Linux中未关闭Firewall
但是我的防火墙是关闭的,hosts文件也确定配置好了。
通过runcluvfy工具来检查:
grid@node74:/home/software/linux_11gR2/grid> ./runcluvfy.sh stage -post hwos -n node74,node76 -verbose

node74:20.20.20.1 node76:20.20.20.2 failed ------注意:两个节点有一组网卡配置了同一网段的IP,但是却没有联通,造成node
connectivity检查失败。

Interfaces found on subnet "172.16.52.0" that are likely candidates for VIP are:
node76 eth0:172.16.54.76 eth0:172.16.54.176
node74 eth0:172.16.54.74 eth0:172.16.54.174 eth0:172.16.54.175
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.
原来是因为两个节点有一对网卡配置了通网段的IP地址,但是实际上两个网卡并没有连通,造成了node connectivity检查失败。

node74:20.20.20.1 node76:20.20.20.2 failed
这样解决办法就有了,要么就是把两个网卡连通,要么就是修改为不同的网段,或者干脆直接停用这两块网卡。
我这边停用这两块网卡后,重新执行安装检查通过。
