centos U盘加载raid卡驱动的方法.docx

有些时候centos Linux内核不存在raid卡的驱动，以前只能用软盘加载驱动，其实是还有其它方法的，只要找到官方相应的驱动，现在Raid卡的品牌很多，但是大部分独立raid卡为highpoint，3ware,adapter,lsi,promise等还有些是集成在主板上的，如果要制作带驱动的iso镜像光盘比较费时间费精力，要很熟悉ISO的目录结构，要把initrd.img文件加入驱动程序进去，然后封装起来，接下来介绍两种比较好的方法。硬件型号为lsi 1064e集成raid卡安装系统centos5.8 Linux首先先介绍第一种方法：第一种方法就是采用linux dd来加载驱动，首先准备一个读卡器和sd卡或者u盘这里是打开u盘所看到的img文件1g的U盘已经变成1.44m了。加载光盘到boot: linux dd加载驱动正在加载usb-storage driver驱动。询问是否要加载驱动选择yes选择sda设备usb设备都是被识别为scsi设备是否要加载/dev/sda设备选择ok是否要加载额外的驱动否=第二种方法：利用linux nostorage首先把u盘分区rootzh888 # fdisk -l/查看所有分区和硬盘Disk /dev/sda: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0007103cDevice Boot Start End Blocks Id System/dev/sda1 * 1 66 524288 83 LinuxPartition 1 does not end on cylinder boundary./dev/sda2 66 1371 10485760 83 Linux/dev/sda3 1371 1632 2097152 82 Linux swap / SolarisDisk /dev/sdb: 1000 MB, 1000341504 bytes/这是第二块u盘的信息为1g31 heads, 62 sectors/track, 1016 cylindersUnits = cylinders of 1922 * 512 = 984064 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x6f20736bDevice Boot Start End Blocks Id Systemrootzh888 # fdisk /dev/sdb/格式化第二块scsi设备u盘WARNING: DOS-compatible mode is deprecated.
