继续这主题，较新的内核启动成功，但它看不到我的sdc- 这是一个硬件 RAID 阵列（级别 10）。
我确信aacraid模块已经加载：
# grep aacraid /2.6.34.14/init
echo "Loading aacraid.ko module"
insmod /lib/aacraid.ko
# lsmod | grep aacraid
aacraid 83347 3

我一直在尝试安装AACRAID 驱动程序，但得到以下信息：
# rpm -ivh aacraid-1.2.1-29900.rpm

我现在该怎么做才能安装 Adaptec RAID 驱动程序？
答案1
正如它所说：2.6.34.14 没有预构建的 aacraid 模块。如果你查询由 安装的所有文件aacraid，你会看到类似这样的内容：
# rpm -ql aacraid-1.2.1-29900
/opt/Adaptec/aacraid/aacraid.spec
/opt/Adaptec/aacraid/aacraid_prebuilt.tgz
/opt/Adaptec/aacraid/aacraid_source.tgz
/opt/Adaptec/aacraid/adpt_mk_initrd
/opt/Adaptec/aacraid/adpt_mkinitrd
/opt/Adaptec/aacraid/chk_lilo
/opt/Adaptec/aacraid/create_device_nodes
/opt/Adaptec/aacraid/grub.awk
/opt/Adaptec/aacraid/install.sh
/opt/Adaptec/aacraid/lilo.awk
/opt/Adaptec/aacraid/module.equiv
/opt/Adaptec/aacraid/read.me
然后解压aacraid_prebuilt.tgz验证：
# cd /opt/Adaptec/aacraid/
# mkdir mods
# tar zxvf aacraid_prebuilt.tgz -C mods/
# ls mods/ | grep 34
#
您要做的是将aacraid源代码复制到内核树（.../drivers/scsi/aacraid），然后重新编译并重试。
# mv /usr/src/linux-2.6.34.14/drivers/scsi/aacraid/ $HOME/aacraid.2.6.34.14.orig
# mkdir /usr/src/linux-2.6.34.14/drivers/scsi/aacraid/
# cd /opt/Adaptec/aacraid
# tar zxvf aacraid_source.tgz -C /usr/src/linux-2.6.34.14/drivers/scsi/aacraid/
# cd /usr/src/linux-2.6.34.14/
# make
# make modules_install
# make install
检查/boot：
# ls -l /boot/ | grep 34

-rw-r--r-- 1 root root 2708848 Apr 10 18:41 vmlinuz-2.6.34.14-withoutraid
以及menu.lst：
title CentOS (2.6.34.14)
root (hd0,0)
kernel /vmlinuz-2.6.34.14 ro root=LABEL=/1 rhgb quiet
initrd /initrd-2.6.34.14.img
title CentOS (2.6.34.14 WITHOUT Adaptec RAID driver)
root (hd0,0)
kernel /vmlinuz-2.6.34.14-withoutraid ro root=LABEL=/1 rhgb quiet
initrd /initrd-2.6.34.14-withoutraid.img
title CentOS (2.6.18-274.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-274.el5 ro root=LABEL=/1 rhgb quiet
initrd /initrd-2.6.18-274.el5.img
然后reboot看看它是否有效：
# df -h /dev/sdc1
Filesystem Size Used Avail Use% Mounted on
/dev/sdc1 5.4T 4.5T 613G 89% /data
# /usr/StorMan/arcconf getconfig 1
