去年写的，貌似不小心删了，现在重新发一下。（个人笔记，写的较粗糙，请见谅）

集群安装时使用了1个scanIP，目前想加到3个，下面是操作过程，集群未使用DNS，数据库版本11.2.0.3

查看目前的SCAN：

[root@oeltan1 ~]# srvctl config scan
SCAN name: oeltan-cluster-scan, Network: 1/192.168.10.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /oeltan-cluster-scan/192.168.10.31

查看SCAN的运行位置：

[root@oeltan1 ~]# srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node oeltan1

停止SCAN

[root@oeltan1 ~]# srvctl stop scan_listener
[root@oeltan1 ~]# srvctl stop scan
[root@oeltan1 ~]# srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is not running

修改hosts

192.168.10.31 oeltan-cluster oeltan-cluster-scan
192.168.10.32 oeltan-cluster oeltan-cluster-scan
192.168.10.33 oeltan-cluster oeltan-cluster-scan

进行修改：

[root@oeltan1 ~]# srvctl modify scan -n oeltan-cluster-scan

确认：

[root@oeltan1 ~]# srvctl config scan
SCAN name: oeltan-cluster-scan, Network: 1/192.168.10.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /oeltan-cluster-scan/192.168.10.31
SCAN VIP name: scan2, IP: /oeltan-cluster-scan/192.168.10.32
SCAN VIP name: scan3, IP: /oeltan-cluster-scan/192.168.10.33

启动：

[root@oeltan1 ~]# srvctl start scan
[root@oeltan1 ~]# srvctl start scan_listener

查看具体状态：

[root@oeltan1 ~]# crsctl stat res -t
