CRS无法启动，运行crsctl start crs无响应
[root@UNID02 ~]# service rawdevices status
/dev/raw/raw5: bound to major 120, minor 97
/dev/raw/raw6: bound to major 120, minor 113
/dev/raw/raw7: bound to major 120, minor 129
发现只起来了三个RAW，于是将其余的RAW起起来。
[root@UNID02 ~]# service rawdevices start
Assigning devices:
/dev/raw/raw1 --> /dev/emcpowera1
/dev/raw/raw1: bound to major 120, minor 1
/dev/raw/raw2 --> /dev/emcpowerb1
/dev/raw/raw2: bound to major 120, minor 17
/dev/raw/raw3 --> /dev/emcpowerc1
/dev/raw/raw3: bound to major 120, minor 33
/dev/raw/raw4 --> /dev/emcpowerd1
/dev/raw/raw4: bound to major 120, minor 49
/dev/raw/raw5 --> /dev/emcpowerg1
/dev/raw/raw5: bound to major 120, minor 97
/dev/raw/raw6 --> /dev/emcpowerh1
/dev/raw/raw6: bound to major 120, minor 113
/dev/raw/raw7 --> /dev/emcpoweri1
/dev/raw/raw7: bound to major 120, minor 129
done
[root@UNID02 ~]#
为什么这些RAW没起来呢？原因为存储发生了故障重启，重启后disk挂载上主机，但是并没有作为RAW被识别出来。
于是再次启动rawservices。
[root@UNID02 ~]# service rawdevices start
Assigning devices:
/dev/raw/raw1 --> /dev/emcpowera1
/dev/raw/raw1: bound to major 120, minor 1
/dev/raw/raw2 --> /dev/emcpowerb1
/dev/raw/raw2: bound to major 120, minor 17
/dev/raw/raw3 --> /dev/emcpowerc1
/dev/raw/raw3: bound to major 120, minor 33
/dev/raw/raw4 --> /dev/emcpowerd1
/dev/raw/raw4: bound to major 120, minor 49
/dev/raw/raw5 --> /dev/emcpowerg1
/dev/raw/raw5: bound to major 120, minor 97
/dev/raw/raw6 --> /dev/emcpowerh1
/dev/raw/raw6: bound to major 120, minor 113
/dev/raw/raw7 --> /dev/emcpoweri1
/dev/raw/raw7: bound to major 120, minor 129
done
[root@UNID02 ~]#
继续查看Messages,发现继续报之前的错误：
Dec 9 08:15:14 UNID02 logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.7259.
看来启动过程中CRS发现还是存在问题，于是再次查看crsctl.*文件：
[root@UNID02 ~]# cat /tmp/crsctl.7259
Oracle Cluster Registry initialization failed accessing Oracle Cluster Registry device: PROC-26: Error while accessing the physical storage Operating System error [Permission denied] [13]
[root@UNID02 ~]#
还是一样的报错，但是这回由[No such file or directory]变成了 [Permission denied]。
肯定是RAW的权限由问题，查看RAW的权限：
[root@UNID02 ~]# ll /dev/raw
total 0
crw------- 1 root root 162, 1 Dec 9 08:14 raw1
crw------- 1 root root 162, 2 Dec 9 08:14 raw2
crw------- 1 root root 162, 3 Dec 9 08:14 raw3
crw------- 1 root root 162, 4 Dec 9 08:14 raw4
crw------- 1 root root 162, 5 Dec 9 08:14 raw5
crw------- 1 root root 162, 6 Dec 9 08:14 raw6
crw------- 1 root root 162, 7 Dec 9 08:14 raw7
果然如此，修改RAW的属主为oracle：
[root@UNID02 ~]# chown oracle:dba /dev/raw/*
发现messages里已经有CRS启动的信息了：
Dec 9 08:16:14 UNID02 logger: Cluster Ready Services completed waiting on dependencies.
Dec 9 08:16:14 UNID02 last message repeated 2 times
Dec 9 08:16:14 UNID02 logger: Running CRSD with TZ =
Dec 9 08:16:14 UNID02 logger: Oracle CSS Family monitor starting.
Dec 9 08:16:15 UNID02 logger: Oracle CSS restart. 0, 1
以为问题到此结束，但等了一会儿，发现asm和instance一直没起来：
[oracle@UNID02 ~]$ crs_stat -t
Name Type Target State Host
