环境：RHEL 6.4 + Oracle 11.2.0.3 + ASM单实例
1.重启主机后,+DATA diskgroup启动不成功,现象如下：
[grid@JY-DB ~]$ crsctl stat res -t

[grid@JY-DB ~]$ srvctl start diskgroup -g data
PRCR-1079 : 无法启动资源 ora.DATA.dg
CRS-5017: The resource action "ora.DATA.dg start" encountered the following error:
ORA-15032: not all alterations performed
ORA-15017: diskgroup "DATA" cannot be mounted
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DATA"
. For details refer to "(:CLSN00107:)" in "/u01/app/11.2.0/grid/log/jy-db/agent/ohasd/oraagent_grid/oraagent_grid.log".
CRS-2674: Start of 'ora.DATA.dg' on 'jy-db' failed

On Linux, at least, a restart of the system will reset the ownership of raw devices. The usual trick is to have some config or init routine reset the ownership.4.检查data磁盘组对应的磁盘设备属主，更改为grid:oinstall
[root@JY-DB ~]# cd /dev/mapper/
[root@JY-DB mapper]# ls
