某个支付系统11.2.0.3的rac系统，其中一个节点忽然无法启动
1.尝试关闭集群重新启动集群
[root@rac2 ~]$ crsctl stop crs -f
2.尝试重新启动集群
[root@rac2 ~]$ crsctl start crs
CRS-4123: Oracle High Availability Services has been started.
集群启动成功，无其他报错，此时感觉asm已经起来了
[grid@rac2 ~]$ ps -ef | grep smon
root 8472 1 1 14:14 ? 00:00:01 /u01/app/11.2/product/crs_1/bin/osysmond.bin

grid 9500 6212 0 14:16 pts/5 00:00:00 grep smon
这时试图连接ASM查看dg状态，奇怪的事情发生了，asm可以登录，但是查询asmdisk报错
[grid@rac2 ~]$ sqlplus / as sysasm
