PRVG-10122 : ASMLib configuration value

环境介绍：

OS版本：RedHat Enterprise Linux Server release 6.4 (Santiago)

DB版本：Oracle 12c

问题描述：

12c RAC环境配置GRID时检查Perform Prerequisite Checks时报错，提示如下：

ASMLib installation and configuration verification. 

- This task checks the ASMLib installation and configuration across the systems.

  Check Failed on Nodes: [rws00abc,  rws00abe]  

Verification result of failed node: rws00abc  Details:

 - 

PRVG-10122 : ASMLib configuration value set to configuration parameter "ORACLEASM_UID" on the node "rws00abc" does not match with cluster nodes 

 - Cause:  The ASMLib configuration check found inconsistent settings across cluster nodes. 

 - Action:  Ensure that the ASMLib is correctly installed and configured on all the nodes with same configuration settings and that the user has the necessary access privileges for the configuration file.

 - 

PRVG-10122 : ASMLib configuration value set to configuration parameter "ORACLEASM_GID" on the node "rws00abc" does not match with cluster nodes 

 - Cause:  The ASMLib configuration check found inconsistent settings across cluster nodes. 

 - Action:  Ensure that the ASMLib is correctly installed and configured on all the nodes with same configuration settings and that the user has the necessary access privileges for the configuration file. 

问题处理：

1. 查看两个节点的oracleasm配置信息

[html] view plain copy

 print?

1. [root@rac01 ~]# oracleasm configure  
2. ORACLEASM_ENABLED=true  
3. ORACLEASM_UID=grid  
4. ORACLEASM_GID=asmadmin  
5. ORACLEASM_SCANBOOT=true  
6. ORACLEASM_SCANORDER=""  
7. ORACLEASM_SCANEXCLUDE=""  
8. ORACLEASM_USE_LOGICAL_BLOCK_SIZE="true"  
9. [root@rac01 ~]#   
10. [root@rac02 ~]# oracleasm configure  
11. ORACLEASM_ENABLED=false  
12. ORACLEASM_UID=  
13. ORACLEASM_GID=  
14. ORACLEASM_SCANBOOT=true  
15. ORACLEASM_SCANORDER=""  
16. ORACLEASM_SCANEXCLUDE=""  
17. ORACLEASM_USE_LOGICAL_BLOCK_SIZE="false"  

由上面的显示信息可知，ASMLib并未在节点rac02上配置，下面就来对节点rac02进行oracleasm配置

2. 节点rac02配置oracleasm

1. [root@rac02 ~]# oracleasm configure -i  
2. Configuring the Oracle ASM library driver.  
3.   
4. This will configure the on-boot properties of the Oracle ASM library  
5. driver.  The following questions will determine whether the driver is  
6. loaded on boot and what permissions it will have.  The current values  
7. will be shown in brackets ('[]').  Hitting <ENTER> without typing an  
8. answer will keep that current value.  Ctrl-C will abort.  
9.   
10. Default user to own the driver interface []: grid  
11. Default group to own the driver interface []: asmadmin  
12. Start Oracle ASM library driver on boot (y/n) [n]: y  
13. Scan for Oracle ASM disks on boot (y/n) [y]: y  
14. Writing Oracle ASM library driver configuration: done  
15. [root@rac02 ~]# oracleasm configure  
16. ORACLEASM_ENABLED=true  
17. ORACLEASM_UID=grid  
18. ORACLEASM_GID=asmadmin  
19. ORACLEASM_SCANBOOT=true  
20. ORACLEASM_SCANORDER=""  
21. ORACLEASM_SCANEXCLUDE=""  
22. ORACLEASM_USE_LOGICAL_BLOCK_SIZE="false"  
23. [root@rac02 ~]#  

3. 继续执行Perform Prerequisite Checks检查，通过
