标题: 使用haip方式往rac中新增一个私网网卡
关于haip的概念,请大家参照百度
我这里场景
rac01,
rac02

私网:
rac01 eth1 180.180.0.1
rac02 eth1 180.180.0.2

现在增加一个新的网卡:
rac01 eth2 180.180.1.1
rac02 eth2 180.180.1.2
和以前的网卡不在一个网络

办法:
1.新增加物理网卡,并设置ip
该操作可以通过os完成.
2.在集群中增加该网卡
# /u01/app/11.2.0/grid/bin/oifcfg setif -global eth2/180.180.1.0:cluster_interconnect
3.增加后,必须关闭两个节点的crs
crsctl stop crs
4.重起两个节点的crs
随便哪个先起都可以
5.检查ip

发现已经有了 169.254.215.30

同时,在
1*  select * from gv$cluster_interconnects
INST_ID NAME          IP_ADDRESS    IS_ SOURCE
---------- --------------- ---------------- --- -------------------------------
      1 eth1:1       169.254.101.194  NO
      1 eth2:1       169.254.215.30 NO
      2 eth1:1       169.254.123.21 NO
      2 eth2:1       169.254.187.97 NO

在报警文件中,也看到

在$CRS_HOME/agent/ohasd/orarootagent/orarootagent.log
中,也将看到类似的信息.

关于测试,在此掠过.
