老师求助一个cvuqdisk 问题
今天看oracle的白皮书，里面有段 这么说的：If you are using Red Hat or SUSE Linux, then you must download and install the operating system package cvuqdisk. Without cvuqdisk, CVU is unable to discover shared disks, and you receive the error message "Package cvuqdisk not installed" when you run CVU. Use the cvuqdisk rpm for your hardware (i386, or for Itanium, ia64).
我理解为：redhat 如果不安装就会认不到共享磁盘。
我们公司要安装 redhat as 464位系统+RAC+ASM
这个是必须安装的吗？
我从字面理解也是这个意思，装吧，即使没用装上也不会有什么影响，反之就不行了
这是一个工具，可以用来检验RAC环境的准备情况。
可以不装。 转了eygle的一个实验，可以看看！
在Linux下，我们同样可以通过cluvfy工具来进行安装环境检查。
这个工具被包含在clusterware安装包中，要使用这个工具还需要先安装一个rpm包。这个包位于clusterware盘的rpm目录下。
$ ls -al rpm
total 28
drwxr-xr-x2 oracle dba 4096 Dec 24 16:05 .
drwxr-xr-x9 oracle dba 4096 Dec 25 10:57 ..
-rw-r--r--1 oracle dba 5339 Jul22005 cvuqdisk-1.0.1-1.rpm
分别在RAC的不同节点安装这个rpm包，安装前需要预设环境变量：
# CVUQDISK_GRP=dba; export CVUQDISK_GRP
# rpm -iv cvuqdisk-1.0.1-1.rpm
Preparing packages for installation...
cvuqdisk-1.0.1-1
安装完成之后可以运行cluvfy工具来检查系统环境配置,在以下输出中，有几个内容需要说明：
1.oinstall用户组可以根据需要建立，如果没有建立，则错误可以忽略
2.Could not find a suitable set of interfaces for VIPs错误是由于Bug导致的
3.compat系列包根据系统具体情况而定，如果存在则错误可以忽略
以下是一个测试的具体输出：
$ ./runcluvfy.sh stage -pre crsinst -n smsdbrac1,smsdbrac2 -verbose
