Oracle RAC 如何增加私网,删除私网以及修改私网相关属性
RAC的私网及其重要,一旦系统配置与gpnp记录不匹配,集群就无法启动,我们往往有这样的需求,增加私网,删除故障私网,或者修改私网属性,这里是完整的测试。也是我们后续一个实施方案的测试过程。这里提示,这个操作需要先备份profile.xml然后必须重启集群,新的配置才能生效。
实施操作前
用户Grid用户备份 每个节点的profile.xml
$ cd $GRID_HOME/gpnp/<hostname>/profiles/peer/
$ cp -p profile.xml profile.xml.bk
查询配置
root@test1 ~]# oifcfg getif
eth0 192.168.56.0 global public
eth1 192.168.57.0 global cluster_interconnect,asm
下面增加两个私网,这是修改OCR,不会改变当前私网运行,新加私网也不会生效
[root@test1 ~]# oifcfg setif -global eth2/192.168.58.0:cluster_interconnect
[root@test1 ~]# oifcfg setif -global eth3/192.168.59.0:cluster_interconnect
[root@test1 ~]# oifcfg getif
eth0 192.168.56.0 global public
eth1 192.168.57.0 global cluster_interconnect,asm
eth2 192.168.58.0 global cluster_interconnect
eth3 192.168.59.0 global cluster_interconnect
观察网卡状态,此时eth2 eth3没有HAIP地址出现,说明没有生效

两个节点都关闭集群,并重启集群
crctl stop crs
crsctl start crs
继续观察私网信息

此时eth1,eth2,eth3都有了haip地址。此时集群的私网配置如下
[root@test1 ~]# oifcfg getif
eth0 192.168.56.0 global public
eth1 192.168.57.0 global cluster_interconnect,asm
eth2 192.168.58.0 global cluster_interconnect
eth3 192.168.59.0 global cluster_interconnect
下面测试修改私网属性并删除一个私网。
1 当前配置
[root@test1 ~]# oifcfg getif
eth0 192.168.56.0 global public
eth1 192.168.57.0 global cluster_interconnect,asm
eth2 192.168.58.0 global cluster_interconnect
eth3 192.168.59.0 global cluster_interconnect
2 修改eth2和eth3的属性,用于asm,此时的setif操作写入OCR。
[root@test1 ~]# oifcfg setif -global eth2/192.168.58.0:cluster_interconnect,asm
[root@test1 ~]# oifcfg setif -global eth3/192.168.59.0:cluster_interconnect,asm
[root@test1 ~]# oifcfg getif
eth0 192.168.56.0 global public
eth1 192.168.57.0 global cluster_interconnect,asm
eth2 192.168.58.0 global cluster_interconnect,asm
eth3 192.168.59.0 global cluster_interconnect,asm
删除私网eth1
[root@test1 ~]# oifcfg delif -global eth1/192.168.57.0
[root@test1 ~]# oifcfg getif
eth0 192.168.56.0 global public
eth2 192.168.58.0 global cluster_interconnect,asm
eth3 192.168.59.0 global cluster_interconnect,asm
关闭并重启集群
crsctl stop crs
crsctl start crs
检查私网信息,此时eth1 没有了HAIP,说明删除成功
