问题现象：启动ora.cssd正常，但是起ASM实例报错ORA-00099。
[grid@db ~]$ crsctl start resource ora.cssd
CRS-2672: Attempting to start 'ora.cssd' on 'db'
CRS-2672: Attempting to start 'ora.diskmon' on 'db'
CRS-2676: Start of 'ora.diskmon' on 'db' succeeded

ORA-15110: no diskgroups mounted
解决思路及方法：
- 查看crs及所有的service的状态，发现DATA未挂载(DISMOUNT)。
可以使用两种方式查看
- 第一种方法
[grid@db ~]$ crsctl status resource

TYPE=ora.diskgroup.type
TARGET=OFFLINE
STATE=OFFLINE
NAME=ora.LISTENER.lsnr
TYPE=ora.listener.type

- 第二种方法

- 查看参数disk_groups发现没有值

- 查看init+ASM.ora文件不存在
[grid@db pfile]$ cd /u01/app/11.2.0/grid/dbs/
[grid@db dbs]$ ls
ab_+ASM.dat hc_+ASM.dat init.ora orapw+ASM
- 去PFILE文件下拷贝控制文件，发现文件夹为空
[grid@db pfile]$ cd /u01/app/grid/admin/+ASM/pfile
[grid@db pfile]$ ls
[grid@db pfile]$
- 重新安装grid软件。
