18C VIP手工切换

场景:
模拟节点2=host02上的vip故障漂移到节点1=host01后,手工切换回到节点2=host02

1.查看资源情况
[grid@host02 ~]$ crsctl stat res -t

从上面的输出看出 ora.host02.vip 是漂移在host02上面的,下面我们模拟将该vip停掉

发现已经没有ens33:1的信息了

4.节点2=host02 的vip已经漂移到了节点1=host01

5.在节点1=host01上可以看到192.168.58.202已经漂移过来了

6.手工漂移回来
srvctl relocate vip -i host02 -n host02

说明不需要进行手工up vip网卡的
[root@host02 bin]# ifconfig ens33:1 up
SIOCSIFFLAGS: Cannot assign requested address
