rac的第二个节点实例无法启动
尝试手动启动
[oracle@rac2 ~]$ export ORACLE_SID=RACDB2
[oracle@rac2 ~]$ sqlplus / as sysdba

显示diskgroup没有mount
那么去ASM下查看diskgroup的状态。并尝试mount

ERROR at line 1:
ORA-00600: internal error code, arguments: [kfgFinalize_2], [], [], [], [], [],

报了ORA-600: [kfgFinalize_2]
上网查证之后：
ASM异常崩溃后，可能会导致ASM实例第一次重新启动出现异常，报ORA-600: [kfgFinalize_2]
终于的解决方法就是停止全部节点上的ASM，重新启动就可以。
