11gr2 RAC SCAN添加IP失败【已解决】

Fung920

问题描述：
原来scan为hosts解析，改为DNS并且添加至三个SCAN VIPs，但是后面添加的IP无法添加进SCAN里面，步骤如下：
1.DNS正反向解析：
[grid@node1:/home/grid]$ host racdb-scan
racdb-scan.oraclema.com has address 192.168.56.112
racdb-scan.oraclema.com has address 192.168.56.110
racdb-scan.oraclema.com has address 192.168.56.111
[grid@node1:/home/grid]$ nslookup racdb-scan
Server:         192.168.56.101
Address:        192.168.56.101#53

Name:   racdb-scan.oraclema.com
Address: 192.168.56.111
Name:   racdb-scan.oraclema.com
Address: 192.168.56.112
Name:   racdb-scan.oraclema.com
Address: 192.168.56.110

[grid@node1:/home/grid]$ nslookup 192.168.56.112
Server:         192.168.56.101
Address:        192.168.56.101#53

112.56.168.192.in-addr.arpa     name = racdb-scan.oraclema.com.
112.56.168.192.in-addr.arpa     name = racdb-scan.


2.现有SCAN及SCAN监听配置：
[grid@node1:/home/grid]$ srvctl config scan
SCAN name: racdb-scan, Network: 1/192.168.56.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /racdb-scan/192.168.56.110
[grid@node1:/home/grid]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

3.根据MOS ID 952903.1修改SCAN信息：
[grid@node1:/home/grid]$ srvctl stop scan_listener
[grid@node1:/home/grid]$ srvctl stop scan
[grid@node1:/home/grid]$ which srvctl
/u01/app/11gr2/grid/bin/srvctl
[root@node1:/root]# /u01/app/11gr2/grid/bin/srvctl modify scan -n racdb-scan
[root@node1:/root]# /u01/app/11gr2/grid/bin/srvctl modify scan_listener -u

4.修改完后查看SCAN配置信息，发现仍然没有改变：
[grid@node1:/home/grid]$ srvctl config scan
SCAN name: racdb-scan, Network: 1/192.168.56.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /racdb-scan/192.168.56.110



[grid@node1:/home/grid]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

[grid@node1:/home/grid]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node node1

依然是只有一个IP，只有一个SCAN监听，有解吗？

你的host 文件没改吧 。把scan ip信息去掉

1.

正是，忘记屏蔽掉原有信息了，
