分析日志后发现: ASM没有启动 OCR等不能启动
问题1:
2018-05-08 11:59:39.980: [? OCRASM][1639659296]proprasmo: Error in open/create file in dg [OCRDG] 2018-05-08 11:59:39.980: [? OCRASM][1639659296]ASM Error Stack : ORA-15077: could not locate ASM instance serving a required diskgroup 2018-05-08 11:59:39.981: [? OCRASM][1639659296]proprasmo: kgfoCheckMount returned [7] |

第二个报错提示: 大概心跳网络有问题
问题2:

ping验证私有网络没有问题

问题1很明显,Oracle rac asm方式,OCR存放在asm里面,启动之前确保asm实例启动
由于服务器重启后没把asm实例带起来。我们必须手工启动asm实例
sqlplus /? sysasm startup 启动asm实例后我们启动集群相关资源 [root@rac1 ~]# crsctl start has CRS-4638: Oracle High Availability Services is online 启动实例资源等 crsctl start cluster –all |

总结:现场人员rac启动顺序不熟悉,Oracle grid root用户命令混用
