11gR2 rac安装详细教程

两台曙光a840-r,一台曙光ds800-f10,操作系统选用oracle linux 6.9 x64,怕7.X太新驱动不匹配没用。存储划分3个10G，5个500G并作好映射。

因rdac多路径软件目前支持6.3，内核2.6.32-279，没有对应的驱动包；用udev+multipath替代oracleasm。

multipath.conf里取别名ocrdisk,dbdisk..,然后用 udev 绑定权限。

安装过程顺利，但重启时，只能启动一个节点，另一节点卡在ora.asm处。

从/var/log/message发现device-mapper: multipath: Failing path 8:0和device-mapper: multipath: Failing path 8:144，这是ocrdisk,不能启动asm。

经查multipath官方资料，双方多路径绑定一致才行。

在节点1, 保证节点不用存储分区

crsctl stop cluster 

crsctl stop has

multipath -F

service multipathd stop

scp /etc/multipath/* db2:/etc/multipath

service multipath start

multipath -v2

multipath -ll

各映射的分区都是running

crsctl start has

crsctl start cluster

节点2

service multipathd start

multipath -v2

multipath -ll

各映射的分区都是running

crsctl start has

crsctl start cluster

crsctl stat res -t
