农大项目（在linux上安装RDAC驱动）

1. 再linux上安装RDAC的时候出错
安装rdac报错
[root@database1 linuxrdac-09.02.C5.13]# make
make V=0 -C/lib/modules/2.6.18-8.el5xen/build M=/root/test2/linuxrdac-09.02.C5.13 MODVERDIR=/lib/modules/2.6.18-8.el5xen/build/.tmp_versions SUBDIRS=/root/test2/linuxrdac-09.02.C5.13 modules
make: *** /lib/modules/2.6.18-8.el5xen/build: 没有那个文件或目录。 停止。
make: *** [mppUpper] 错误 2

说没有找到目录.

解决这个问题
2).仔细看rdac 安装的readme
1〉HBA 支持的型号
HBA Support
================================================================
The RDAC driver is supported on the following host
bus adapters:
iSCSI Qlogic
PCI-X :Qlogic 4050C, Qlogic 4052C
PCI-E :Qlogic 4060C, Qlogic 4062C

Fibre Channel Qlogic
PCI-E : QLE2460, QLE2462 (4Gb)
PCI-E : QLE236x (2Gb)
PCI-X : QLA2460, QLA2462 (4Gb)
PCI-X : QLA2310F, QLA2340, QLA2342 (2Gb)
PCI-X : QLA2000 (1Gb)

SAS LSI Logic
PCI-X : LSISAS3800-X, LSI SAS3442X-R, LSI SAS3442E-R

Fibre Channel LSI Logic:
PCI-X : LSI7204XP-LC, LSI7404XP-LC, LSI7104XP, (4Gb)
PCI-X : LSI7202XP, LSI7402XP (2Gb)
LSI7104EP, LSI7204EP

2〉. Co-existence with QLogic and LSI failover drivers
================================================================
The RDAC driver cannot co-exist with an HBA-level failover
driver such as the Emulex, QLogic or LSI Logic HBA failover drivers.
RDAC不能和lsi 或QLOGIC的容错驱动共存

3> Requirements before RDAC driver package installation
-----------------------------------------------------------
a. It's assumed that the host system that you are
installing the RDAC driver to has Supported HBA's.

b. Although the system can have Fibre Channel HBAs from
multiple vendors or multiple models of HBAs from the
same vendor, only the same model of HBAs can be
connected to each Storage Array.

c. It is assumed that the low level HBA driver has been
properly built and installed before RDAC driver
installation.

d. The standard HBA driver needs to be loaded before
the RDAC driver installation. The HBA driver has to
be a non-failover driver.

For QLogic HBAs, the base driver is named "qla2xxx"
and host driver is named "qla2300" .

For LSI Logic HBAs, the port driver is named
mptbase and the host driver is named mptscsi or
mptscsih, for the mpt driver version earlier than
3.02.xx. The 3.02.xx or later LSI mpt driver splits to three
driver modules - mptspi, mptsas and mptfc for SCSI parallel
interface transport, SAS transport and Fibre Channel
transport respectively.

e. On the SuSE operating system, it is assumed that the
low level HBA driver names are included in
INITRD_MODULES in /etc/sysconfig/kernel.

For the systems that have QLogic HBA's, the modules
file should include a qla2xxx and qla2300 ( or qla2300).

For the systems that have LSI Logic HBAs, INITRD_MODULES
should include mptbase and mptscsi (or mptscsih)
for pre-3.02.xx version of LSI mpt driver. The INITRD_MODULES
should include mptbase, mptscsi, mptspi, mptsas and mptfc
for 3.02.xx or later version of LSI mpt driver.

For the systems that have IBM Emulex HBAs, INITRD_MODULES
should include lpfcdd or lpfc.

f. The kernel source tree for the kernel version to be
built against should already be installed before
RDAC driver package installation.

g. The glibc-devel(64 bit) package is required for 64 bit machines.

总结前面的英文：
RDAC被安装前需要的的条件：a.系统里有支持的HBA卡，b:系统同时连到磁盘阵列的HBA卡型号必须一至。C.
D.HBA卡的驱动必须是STANDARD类型，而不是 带失败切换的驱动。E:对于QLOGIC的，需要安装ALA2XXX 和qla2300
f:kernel source tree 应该先被安装 g:对于64位的机器 需要安装 glibc-devel（64bit)

感觉条件都达到了，除非QLOGIC的HBA驱动不行，但是我们从主机已经可以看到盘阵了，所以应该不是HBA驱动不行的原因，
很可能是REDHAT上面还差几个支持包没有打好，导致不能够

4〉lsmod 察看qlogic 的HBA卡驱动程序是否安装：

在网上找到解决方法：
说安装报那个错误的原因是没有安装合适的包。
1>安装如下几个包：（红色的）
compat-gcc-34-3.4.6-4.i386.rpm kernel-PAE-devel-2.6.18-8.el5.i686.rpm
compat-gcc-34-c++-3.4.6-4.i386.rpm kernel-xen-devel-2.6.18-8.el5.i686.rpm
compat-libstdc++-33-3.2.3-61.i386.rpm libXp-1.0.0-8.i386.rpm
kernel-2.6.18-8.el5.i686.rpm rdac-LINUX-09.02.C5.13-source.tar.gz
kernel-devel-2.6.18-8.el5.i686.rpm sysstat-7.0.0-3.el5.i386.rpm
kernel-PAE-2.6.18-8.el5.i686.rpm

2.>解压缩rdac-LINUX-09.02.C5.13-source.tar.gz
并在上面安装 make
make install
安装后，在boot 菜单上生成了文件 mpp-2.6.18-8.el5xen.img

3.>把编译后的内核作为img的启动引导
vi /boot/grub/menu.lst
把最后一行的img文件注释掉掉，加入刚才生成的img文件
title Red Hat Enterprise Linux Server (2.6.18-8.el5xen)
root (hd0,0)
kernel /boot/xen.gz-2.6.18-8.el5
module /boot/vmlinuz-2.6.18-8.el5xen ro root=LABEL=/ rhgb quiet
module /boot/mpp-2.6.18-8.el5xen.img
