一.检查ASM
[root@rac1 ~]# /etc/init.d/oracleasm status
Checking if ASM is loaded: yes
Checking if /dev/oracleasm is mounted: yes
[root@rac1 ~]# /etc/init.d/oracleasm listdisks
ASM01
ASM02
ASM03
二.RAC自动启动的时候后台CRS进程
[root@rac1 ~]# ls -l /etc/init.d/init.*
-r-xr-xr-x 1 root root 1951 Aug 20 11:57 /etc/init.d/init.crs
-r-xr-xr-x 1 root root 4722 Aug 20 11:57 /etc/init.d/init.crsd
-r-xr-xr-x 1 root root 35402 Aug 20 11:57 /etc/init.d/init.cssd
-r-xr-xr-x 1 root root 3198 Aug 20 11:57 /etc/init.d/init.evmd
NAME=ora.RACDB.RACDB2.inst

STATE=ONLINE on rac2

TYPE=application
TARGET=ONLINE
STATE=OFFLINE on rac2

TYPE=application
TARGET=ONLINE
STATE=UNKNOWN on rac2
。。。
1.对于OFFLINE的进程可以手动启动
[root@rac1 bin]# ./crs_start ora.rac2.gsd
Attempting to start `ora.rac2.gsd` on member `rac2`
Start of `ora.rac2.gsd` on member `rac2` succeeded.
2.对于UNKNOWN的进程 可以先./crs_stop .... 后再 ./crs_start
