进一步确认scan ip 和 scan listener 运行在那个节点
[grid@rac-1 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node rac-1
[grid@rac-1 ~]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node rac-1
从信息看，scan ip 运行在rac-1 节点。下面手动将scan ip 切换到rac-2 节点
我们将使用srvctl relocate scan_listener命令，下面是这个命令的帮助文档
[grid@rac-1 ~]$ srvctl relocate scan_listener -help
Temporarily relocate SCAN listener from one node of the cluster to another.
Usage: srvctl relocate scan_listener -i
-i
-n
-h Print usage
[grid@rac-1 ~]$
执行该命令
[grid@rac-1 ~]$ srvctl relocate scan_listener -i 1 -n rac-2
检查scan ip 信息，发现scan ip 已经运行在rac-2节点了。
[grid@rac-1 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node rac-2
[grid@rac-1 ~]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node rac-2
[grid@rac-1 ~]$ crsctl stat res -t
