客户对asm进行扩容,执行udev_start命令之后,所有的vip全部漂移,业务全部中断
优先恢复业务,把所有vip漂移回来
[grid@rac3 ~]$ srvctl relocate vip -i rac1 -n rac1 -f -v VIP was relocated successfully. [grid@rac3 ~]$ srvctl relocate vip -i rac2 -n rac2 -f -v VIP was relocated successfully. [grid@rac3 ~]$ srvctl relocate vip -i rac3 -n rac3 -f -v VIP was relocated successfully. [grid@rac3 ~]$ srvctl relocate vip -i rac4 -n rac4 -f -v VIP was relocated successfully.
vip恢复正常，业务也恢复正常
出现该问题的原因是由于udev_start命令引起网卡瞬间中断,从而使得vip发生漂移
查看ifcfg配置文件
引起该问题的原因是udev对网卡进行了操作,从而引起该问题,处理建议在对应的ifcfg文件中加上 HOTPLUG=”no” （pulbic,private和其他需要关注的网络）
