RAC 哪个节点先启动HA就哪个节点实例能启动的问题
前面都一直好好的，RAC的两个节点都一切运行正常，可是我出差了一个多月回来检查数据库的时候发现只有一个节点的实例在运行，另一个节点怎么都启动不了，后来将服务器重启了也不行，后来无意中发现哪个节点先启动HA，那个节点就能正常启动所有实例，而后启动的一个实例都启动不了，真怪... 显示全部

你要先查清楚盘和node的对应关系：
# ls -l /dev |grep rOCRFile
会显示一个类似的东西出来：
crw-r----1 root oinstill 24, 8192 Aug 10 2010 /dev/rOCRFile
注意： 24， 8192是major number
# ls -l /dev |grep "2 ...

$ ls -l /dev |grep rOCRFile
crw-r----- 1 root oinstall 44, 1 Oct 13 14:15 rOCRFile
crw-r----- 1 root oinstall 44, 2 Oct 13 14:15 rOCRFileMirror
$ ^C
$ ls -l /dev |grep "44, 1"
brw-rw---- 1 root system 44, 1 Aug 10 13:38 OCRFile
crw-r----- 1 root oinstall 44, 1 Oct 13 14:16 rOCRFile
两个节点都是一样的结果，我是将lspv中显示concurrent的盘全部执行了chdev -l hdiskn -a reserve_policy=no_reserve
这样有问题么？之前这几个全是reserve_policy = single_path
