linux安装oracle RAC的时候，挂载lun的时候，需要安装多路径软件RDAC，具体步骤如下：

下载package的地址为: http://support.netapp.com/NOW/public/apbu/oemcp/

1,安装需要的package：

tar -zxvf rdac-LINUX-09.03.0C05.0652-source.tar.gz

cd linuxrdac-09.03.0C05.0652/

若没有支持6.4的安装包，可以下载6.3的，能用

2,之后需要make，make install，但是缺少package，所以需要使用yum 安装kernel-devel,gcc之类的包

yum install kernel-devel

yum install gcc*



3,需要在rdac解压目录中执行如下步骤

make

make install



4,make install之后根据提示修改/boot/efi/EFI/redhat/grub.conf中的内容,redhat的版本不一样，

修改的文件也不一样，redhat6.4修改的是/boot/efi/EFI/redhat/grub.conf这个文件。

添加内容如下(粗体部分为新加或修改内容):

[root@wlcspdb1 ~]# more /boot/efi/EFI/redhat/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
