oracle rac手动切换scan ip到集群其他节点 

srvctl relocate scan用法：
[grid@rac1 ~]$ srvctl relocate scan -h

将 SCAN VIP 从集群的一个节点临时重新定位到另一个节点。

用法: srvctl relocate scan -i <ordinal_number> [-n <node_name>]
    -i <scan_ordinal_number> IP 地址的序数
    -n <node_name>           SCAN VIP 节点名
    -h                       输出用法
    
一、背景
1）节点一ip配置
#rac1
192.168.162.10      rac1
192.168.162.11      rac1-vip
10.10.10.11         rac1-priv

#rac2
192.168.162.12      rac2
192.168.162.13      rac2-vip
10.10.10.12         rac2-priv

#scan-ip
192.168.162.14      scan-cluster

2）节点二ip配置
#rac1
192.168.162.10      rac1
192.168.162.11     rac1-vip
10.10.10.11         rac1-priv

#rac2
192.168.162.12      rac2
192.168.162.13      rac2-vip
10.10.10.12         rac2-priv

#scan-ip
192.168.162.14      scan-cluster

二、手动切换scan ip到集群其他节点：
1）查看节点一，节点二scan ip切换前ip以及listener_scan1状态
节点一：
[grid@rac1 ~]$ ip a

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:50:56:23:a9:13 brd ff:ff:ff:ff:ff:ff

       valid_lft forever preferred_lft forever
    inet6 fe80::250:56ff:fe23:a913/64 scope link
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:50:56:21:3a:ae brd ff:ff:ff:ff:ff:ff
    inet 10.10.10.11/24 brd 10.10.10.255 scope global eth1
       valid_lft forever preferred_lft forever
    inet 169.254.83.129/16 brd 169.254.255.255 scope global eth1:1
       valid_lft forever preferred_lft forever
    inet6 fe80::250:56ff:fe21:3aae/64 scope link
       valid_lft forever preferred_lft forever

节点二：

2）手动切换scan ip
[grid@rac1 ~]$ srvctl relocate scan -i 1 -n rac2
