通常装好系统后,开机硬盘会在/dev/sda,但接上array后,常常就变成/dev/sdb去了,导致无法开机.

1.change /etc/modules.conf

将scsci adapter的顺序调换,改成如下所示：

<ccid_nobr>

<ccid_code>alias scsi_hostadapter mptbase # sda 

alias scsi_hostadapter1 mptscsih # sda 

alias scsi_hostadapter2 aic7xxx #应该是sdb却跑到sda去的

2.更新开机ramdisk

确认核心版本

#uname -a

再来就是重建开机ramdisk

#mv /boot/initrd-2.4.35.3-1trsmp.img /boot/initrd-2.4.35.3-1trsmp.img.orig #mkinitrd /boot/initrd-2.4.35.3-1trsmp.img 2.4.35.3-1trsmp

3.reboot后检视scsi adapter顺序是否正确.
