asmca无法创建ASM磁盘

现象

grid用户使用asmca无法创建asm磁盘，如下图

分析

如图所示，报错说是 Grid Infrastructure 出了问题。那么 Grid Infrastructure 是什么 ？

在安装 Grid 时，会执行一个脚本 /u01/app/11.2.0/grid/root.sh ，该脚本执行内容如下

Performing root user operation for Oracle 11g

The following environment variables are set as:
    ORACLE_OWNER= grid
    ORACLE_HOME=  /u01/app/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]: 
The contents of "dbhome" have not changed. No need to overwrite.
The contents of "oraenv" have not changed. No need to overwrite.
The contents of "coraenv" have not changed. No need to overwrite.

Adding Clusterware entries to upstart

data     2015/09/10 16:06:10     /u01/app/11.2.0/grid/cdata/data/backup_20150910_160610.olr
Successfully configured Oracle Grid Infrastructure for a Standalone Server

注意最后一句，Grid Infrastructure 配置成功。该脚本所配置的内容就是 Grid Infrastructure 。该部分出问题时，该脚本都会给出提示，比如，

如果“Adding Clusterware entries to upstart”没有启动成功，那么脚本就会给出以下提示

To configure Grid Infrastructure for a Stand-Alone Server run the following command as the root user:

/u01/app/11.2.0/grid/perl/bin/perl -I/u01/app/11.2.0/grid/perl/lib -I/u01/app/11.2.0/grid/crs/install /u01/app/11.2.0/grid/crs/install/roothas.pl

To configure Grid Infrastructure for a Cluster execute the following command:

/u01/app/11.2.0/grid/crs/config/config.sh

This command launches the Grid Infrastructure Configuration Wizard. The wizard also supports silent operation, and the parameters can be passed through the response file that is available in the installation media.

 

意思是如果安装步骤没有问题，只是启动由于某种原因没有成功时，

单机可以执行 /u01/app/11.2.0/grid/crs/install/roothas.pl

集群可以执行 /u01/app/11.2.0/grid/crs/config/config.sh

以启动服务

解决方法

1. 检查确认安装过程是否正确

2. 检查集群服务是否正常启动，如果没有

    单机执行 /u01/app/11.2.0/grid/crs/install/roothas.pl

    集群执行 /u01/app/11.2.0/grid/crs/config/config.sh

    以启动服务
