[grid@rac-1 ~]$ 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 <ordinal_number> [-n <node_name>]
    -i <scan_ordinal_number> Ordinal number of IP address
    -n <node_name>           SCAN VIP node name
    -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
