确定/etc/hosts档未有对scan的解析---本例是拿掉hosts里面的

Add the scan network to crs resource---

[root@ksa034 oracle]# crs_stop -all

[root@ksa034 oracle]# crs_start -all

[root@ksa034 oracle]# srvctl status scan;

正式启动scan_listener和scan服务，检查状态如下:

[root@ksa034 oracle]# srvctl start scan;

[root@ksa034 oracle]# srvctl start scan_listener

[root@ksa034 oracle]# crsctl status resource -t;
