dell服务器在redhat5.2上会出现硬盘无辜掉线的情况
一，dell 2970的服务器
突然出现系统不能使用，dmesg信息出现：
sd 0:2:0:0: rejecting I/O to offline device
sd 0:2:0:0: rejecting I/O to offline device
sd 0:2:0:0: rejecting I/O to offline device
sd 0:2:0:0: rejecting I/O to offline device
操作系统：
[root@test ~]# cat /etc/issue
Red Hat Enterprise Linux Server release 5.2 (Tikanga)
Kernel r on an m
[root@test ~]#
通过系统查看硬盘：
[root@test at]# fdisk -l
Disk /dev/sdb: 218.0 GB, 218020577280 bytes
255 heads, 63 sectors/track, 26506 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
没有发现sda硬盘的信息，sda硬盘就是服务器的系统盘。
二，今天又发现一台dell 2900的服务器
操作系统：
[root@tonykorn ~]# cat /etc/issue
Red Hat Enterprise Linux Server release 5.2 (Tikanga)
Kernel r on an m
[root@tonykorn ~]#
出现和上面相同的情况。
三，安装dell光盘中raid驱动，然后继续观察 。
1,取得驱动程序文件
[root@test ~]# cd /mnt/SERVICE/pexxxx/sas_raid/r169676
[root@test r169676]# ls
megaraid_sas-v00.00.03.16.tgz
[root@test r169676]# cp megaraid_sas-v00.00.03.16.tgz /root
2，查看module信息：
[root@test ~]# lsmod

3，安装驱动
