容器版系统在使用华为V5服务器时驱动升级方法

问题描述

在华为 RH 1288V5 服务器（对应RAID是 LSI 3408)安装容器版系统BC-Linux for LDK V7.4时，在选择默认使用4.9高版本BEK内核启动，会出现无法正常进入系统情况。

问题原因分析

由于BC-Linux for LDK V7.4版本系统的高版本内核kernel-bek-4.9.82-100.el7.bclinux.x86_64版本发布较早，未合入较华为服务器新的raid驱动。

影响版本

BC-Linux for LDK V7.4

升级方法

1.下载对应的驱动软件版本

首先下载对应的raid驱动软件包，下载链接：
http://mirrors.bclinux.org/bclinux/kernel/bek/el7.4/x86_64/Packages/kmod-bclinux-megaraid_sas-bek-07.706.07.00-3.el7_4.bclinux.x86_64.rpm

2.安装驱动软件

从3.10版本内核进入系统，安装驱动软件。

[root@localhost ~]# rpm -ivh kmod-bclinux-megaraid_sas-bek-07.706.07.00-3.el7_4.bclinux.x86_64.rpm 
Preparing...                          ################################# [100%]

   1:kmod-bclinux-megaraid_sas-bek-07.################################# [100%]
[root@localhost ~]# rpm -aq | grep kmod-bclinux-megaraid_sas-bek
kmod-bclinux-megaraid_sas-bek-07.706.07.00-3.el7_4.bclinux.x86_64

3.为高版本内核更新initramfs文件

[root@localhost ~]# dracut -f /boot/initramfs-4.9.82-100.el7.bclinux.x86_64.img 4.9.82-100.el7.bclinux.x86_64

4.重启系统

重启系统，从高版本内核进入系统，如果系统能正常启动，则证明驱动升级完成。驱动升级后建议现网监测一段时间看是否完全兼容。
