[Exadata常规管理] 安装11G RAC的GI时遇到的scan IP的问题

1^#

发表于 2013-3-13 10:38:55 | 查看: 11520| 回复: 7

求助！！！在安装11G的GI的时候，填写scan地址的时候报错
[INS-40719] IP address configured for Single Client Access Name (SCAN): rac-scan is already assigned to another system.
Cause - The installer could not find the IP addresses you selected as SCAN addresses. This may be because they are assigned to another system, or because the IP addresses are not listed in the DNS or hosts files as assigned to this domain name.  Action - Enter resolvable IP addresses to use as SCAN addresses.

这是hosts文件的内容
# Public
192.168.100.81  rac1.localdomain rac1
192.168.100.82  rac2.localdomain rac2
#Private
10.10.10.1  rac1-priv.localdomain rac1-priv
10.10.10.2  rac2-priv.localdomain rac2-priv
#Virtual
192.168.100.83  rac1-vip.localdomain rac1-vip
192.168.100.84  rac2-vip.localdomain rac2-vip
#scan
192.168.100.189  rac-scan.localdomain rac-scan

使用DNS的正反向解析都是正确的
[root@RAC1 logs]# nslookup rac-scan
Server:       192.168.100.189
Address:       192.168.100.189#53

Name: rac-scan.localdomain
Address: 192.168.100.189

[root@RAC1 logs]# nslookup 192.168.100.189
Server:       192.168.100.189
Address:       192.168.100.189#53

189.100.168.192.in-addr.arpa name = rac-scan.localdomain.

[root@RAC1 logs]# cat /etc/resolv.conf
search localdomain
nameserver 192.168.100.189

使用的是esxi 5.1虚拟机安装的
操作系统是rhel 5.7
ORACLE gird的版本是11.2.3
其中RAC1、RAC2、DNS都是独立的虚拟机

192.168.100.189,这个是我配的DNS的IP地址啊

我改DNS地址之前，已经ping 过了，没有人用，我才改的DNS的配置文件
然后service network restart的，然后DNS主机的IP地址才变成的192.168.100.189
然后我了两台RAC的/etc/hosts文件和/etc/resolv.conf文件，把对应的IP地址改成了192.168.100.189

没搞懂你什么意思

不管你怎么配 scan-ip在安装前不该被ping通

查了一下RAC1节点的IP,发现192.168.100.189跑到eth0;2上去了，请问怎么弄掉网卡上的这个IP地址？
我reboot系统也没有用。
