linux安裝oracle RAC的時(shí)候，掛載lun的時(shí)候，需要安裝多路徑軟件RDAC，具體步驟如下：

1,安裝需要的package：

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

cd linuxrdac-09.03.0C05.0652/

若沒(méi)有支持6.4的安裝包，可以下載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 安裝kernel-devel,gcc之類的包

yum install kernel-devel

yum install gcc*

3,需要在rdac解壓目錄中執(zhí)行如下步驟

make

make install

4,make install之后根據(jù)提示修改/boot/efi/EFI/redhat/grub.conf中的內(nèi)容,redhat的版本不一樣，

修改的文件也不一樣，redhat6.4修改的是/boot/efi/EFI/redhat/grub.conf這個(gè)文件。

添加內(nèi)容如下(粗體部分為新加或修改內(nèi)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

# NOTICE: You have a /boot partition. This means that

# all kernel and initrd paths are relative to /boot/, eg.

# root (hd0,1)

# kernel /vmlinuz-version ro root=/dev/mapper/VolGroup-lv_root

# initrd /initrd-[generic-]version.img

#boot=/dev/sda1
