安装RAC的时候，使用ASM作为存储文件的系统，在创建数据库的时候，出现故障现象如下：

rac1-> crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....SM1.asm application    ONLINE    ONLINE    rac1
ora....C1.lsnr application    ONLINE    UNKNOWN   rac1
ora.rac1.gsd   application    ONLINE    UNKNOWN   rac1
ora.rac1.ons   application    ONLINE    UNKNOWN   rac1
ora.rac1.vip   application    ONLINE    ONLINE    rac1
ora....SM2.asm application    ONLINE    UNKNOWN   rac2
ora....C2.lsnr application    ONLINE    UNKNOWN   rac2
ora.rac2.gsd   application    ONLINE    UNKNOWN   rac2
ora.rac2.ons   application    ONLINE    UNKNOWN   rac2
ora.rac2.vip   application    ONLINE    ONLINE    rac2

节点1是ONLINE，而节点2是“UNKNOWN”状态；这个时候，创建ASM磁盘组，肯定会报CRS-0023的错误。

解决办法：

1.查看ASM的状态：

rac1-> srvctl status asm -n rac1
ASM 实例 +ASM1 正在节点 rac1 上运行。
rac1-> srvctl status asm -n rac2
ASM 实例 +ASM2 不在节点 rac2 上运行。

2.查看CRS是否配置正确：

rac1-> crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

3.强制关闭CRS的所有服务：

rac2-> crs_stop -all
Attempting to stop `ora.rac2.LISTENER_RAC2.lsnr` on member `rac2`
Attempting to stop `ora.rac1.ASM1.asm` on member `rac1`
Stop of `ora.rac2.LISTENER_RAC2.lsnr` on member `rac2` succeeded.
Attempting to stop `ora.rac2.ASM2.asm` on member `rac2`
Stop of `ora.rac2.ASM2.asm` on member `rac2` succeeded.
Attempting to stop `ora.rac2.vip` on member `rac2`
Stop of `ora.rac1.ASM1.asm` on member `rac1` succeeded.
Attempting to stop `ora.rac1.LISTENER_RAC1.lsnr` on member `rac1`
Stop of `ora.rac2.vip` on member `rac2` succeeded.

Attempting to stop `ora.rac1.vip` on member `rac1`
Stop of `ora.rac1.vip` on member `rac1` succeeded.

4.开启CRS的所有服务：

rac1-> crs_start -all
Attempting to start `ora.rac1.vip` on member `rac1`
Attempting to start `ora.rac2.vip` on member `rac2`
Start of `ora.rac1.vip` on member `rac1` succeeded.
Attempting to start `ora.rac1.ASM1.asm` on member `rac1`
Start of `ora.rac2.vip` on member `rac2` succeeded.
Attempting to start `ora.rac2.ASM2.asm` on member `rac2`
Start of `ora.rac2.ASM2.asm` on member `rac2` succeeded.
Attempting to start `ora.rac2.LISTENER_RAC2.lsnr` on member `rac2`
Start of `ora.rac2.LISTENER_RAC2.lsnr` on member `rac2` succeeded.
Start of `ora.rac1.ASM1.asm` on member `rac1` succeeded.
Attempting to start `ora.rac1.LISTENER_RAC1.lsnr` on member `rac1`

3.问题解决：
