**Oracle Study之--Oracle 11gR2 RAC crs启动故障**

**系统环境：**

**    操作系统：RedHat EL5**

**    Cluster：  Oracle 11gR2 Grid**

**    Oracle：   Oracle 11gR2 **

RAC环境中，其中一个节点crsd进程启动失败：

\[grid@wyb666 ~\]$ crsctl check crs  
CRS-4638: Oracle High Availability Services is online  
CRS-4535: Cannot communicate with Cluster Ready Services  
CRS-4529: Cluster Synchronization Services is online  
CRS-4533: Event Manager is online

**1、查看日志**  
\[root@wyb666 ~\]\# cd /u01/11.2.0/grid/log  
\[root@wyb666 log\]\# ls  
crs  diag  wyb666  
\[root@wyb666 log\]\# cd wyb666/  
\[root@wyb666 wyb666\]\# ls  
admin  alertwyb666.log  crsd  ctssd    evmd   gnsd   mdnsd  racg  
agent  client           cssd  diskmon  gipcd  gpnpd  ohasd  srvm  
\[root@wyb666 wyb666\]\# cd crsd  
\[root@wyb666 crsd\]\# ls

\[root@wyb666 crsd\]\# tail crsd.log   
2015-06-08 11:41:28.430: \[  OCRASM\]\[3046103824\]proprasmcl: asmhandle is NULL

ORA-15077: could not locate ASM instance serving a required diskgroup  
\] \[7\]  
2015-06-08 11:41:28.430: \[    CRSD\]\[3046103824\]\[PANIC\] CRSD exiting: Could not init OCR, code: 26  
2015-06-08 11:41:28.430: \[    CRSD\]\[3046103824\] Done.

**从以上可以看出：在crs service启动时，无法访问OCR磁盘，访问ASM DISKGROUP 失败！**

**2、查看ASM磁盘组信息**  
**\[root@wyb666 crsd\]\# service oracleasm listdisks**  
ASM\_DATA1  
ASM\_DATA2  
ASM\_RCY1  
ASM\_RCY2  
OCR\_VOTE1  
OCR\_VOTE2  
OCR\_VOTE3  
**\[root@wyb666 crsd\]\# ls -l /dev/oracleasm/disks**  
total 0  
brw-rw---- 1 grid asmadmin 8, 21 Jun  8 09:23 ASM\_DATA1  
brw-rw---- 1 grid asmadmin 8, 22 Jun  8 09:23 ASM\_DATA2  
brw-rw---- 1 grid asmadmin 8, 23 Jun  8 09:23 ASM\_RCY1  
brw-rw---- 1 grid asmadmin 8, 24 Jun  8 09:23 ASM\_RCY2  
brw-rw---- 1 grid asmadmin 8, 17 Jun  8 11:53 OCR\_VOTE1  
brw-rw---- 1 grid asmadmin 8, 18 Jun  8 11:53 OCR\_VOTE2  
brw-rw---- 1 grid asmadmin 8, 19 Jun  8 11:53 OCR\_VOTE3

**解决方法：**

重新启动CRS服务，然后再手工启动ASM Instance：

**启动ASM Instance**
