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
