CRS-4639: Could not contact Oracle High Availability Services

原因,crs没有启动
方法1、oracle中的bug,
启动之前需要执行
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1   (如果想让重启能够执行,需要加入rc.local中,两个节点)
然后再执行
[root@rac2 bin]# ./crsctl start crs

方法1如果不行可以尝试方法2

[root@rac2 install]# /u01/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force -verbose

然后重新配置
[root@rac2 grid]# ./root.sh 
Running Oracle 11g root.sh script...

The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /u01/app/11.2.0/grid
    ...
即可
如果是centos6以上还需要运行
[root@rac2 ~]# /bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1

检查
[root@rac2 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online


另外,注意的是,如果还是在重启服务器之后不能启动crs,则需要在启动crs之前执行命令(两个节点)
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
追根就是oracle的一个bug

[root@rac2 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager
这个问题有几个原因
1、使用./crsctl start crs 之后立即执行了check,需要等待
2、需要查看节点连通状态,公有网络私有等,还有就是disk的属性
[root@rac2 disks]# ll
total 0
brw-rw---- 1 oracle dba 8, 17 Feb 10 23:47 DISK5
brw-rw---- 1 oracle dba 8, 33 Feb 10 23:47 DISK6


在启动asm实例的时候报如下错误

[grid@b1 ~]$ sqlplus / as sysasm

然后用crsctl check css检查的时候报如下错误:

[grid@b1 ~]$ crsctl check css
