怎样安装磁盘阵列？

MicroHard

在redhat 8.0 下，我有阵列柜外接在AHA-2940卡上，我怎么能让redhat使用它呢？

answer

fdisk分区，
如果你是第一个SCSI硬盘那设备名是/dev/sda
如果你的是第二块SCSI那么就是/dev/sdb。

MicroHard

我不能找到阵列呀！无论是sda,sdb或是其它的设备，只能找到别一块scsi硬盘

先装上scsi卡驱动。

你肯定将阵列接到2940上，这么慢的SCSI接口？不是什么别的比如IBM SERVER RAID卡？

MicroHard

是啊，我是将阵列接在2940卡上的，我没有server raid卡，以前系统装的SCO Openserver，阵列可以正常工作，自从换成了RedHat 就没有找到过阵列了！是不是还要装别的什么驱动呢？（除了SCSI卡的驱动外）？？用dmesg得到的结果显示系统是找到了2940卡的，就是找不到阵列（我已做好Raid5）。

wolfop

嗯，这个就不知道了，外置的阵列看看有没有相应的给LINUX的驱动。

什么阵列，外制硬盘合吧？

如果你将阵列花城多个逻辑盘,同时挂在一个id下,就会产生多lun的情况
linux的kernel默认为只读一个id下的第一个lun(只能认出第一个逻辑盘),如果要用多个lun就要编译kernel
在sco下好像只要配一下........不好意思忘记了.....^_^

我只有一个逻辑盘，用dmesg有如下信息：

请注意redhat检测到了2940卡，却没有硬盘信息！
