Sugon A420r-G installation centos5.5 I, environment server: Sugon sky wide A420r-G Operating system: centos 5.5 x86-64 server comes with three GB hard disk, and through RAID card set as RAID 5 disk array, however, during the system installation process, it was unable to be smoothly installed because of the lack of RAID card drivers, so I contacted Sugon customer service and obtained the driver from the random navigation disc, however, since the driver is not in the required img format, it cannot be loaded. Previously, I tried the following methods one by one through Baidu queries, and all of them failed. Www.2cto.com 1. copy the drive to the USB flash drive (fat32 format) and load it by running the linux dd command during installation. 2. the method is the same as 1, but the USB flash drive format is fat, failure 3. the method is the same as above. it only formats the USB flash disk to the ext3 format. failure 4. As for the above, the driver to the root directory of the USB flash disk fails. it seems that only the img format is feasible, but I don't have an img driver at hand. what should I do? I can make an img file by myself through online query. the method is as follows: 2. the code below the img file is the actual operation command, add the following comments to the Red content: [root @ localhost/] # mkfs. ext3-m0/dev/ram1 # Format/dev/ram1 to ext3 file system mke2fs 1.39 (29-May-2006) Filesystem label = OS type: linux Block size = 1024 (log = 0) Fragment size = 1024 (log = 0) 40 96 inodes, 16384 blocks 0 blocks (0.00%) reserved for the super user First data block = 1 Maximum filesystem blocks = 16777216 2 block groups 8192 blocks per group, 8192 fragments per group 2048 inodes per group Superblock backups stored on blocks: 8193 Writing inode tables: done Creating journal (1024 blocks): doneWriting superblocks and filesystem accounting information: done This filesystem will be Automatically checked every 21 mounts or180 days, whichever comes first. use tune2fs-c or-I to override.

Select yes, then sda, and then select the newly created img file raid. img. press enter to load the driver file. When asked, do you want to load any more driver disks? Select No, and then it will be exactly the same as installing linux. 4. Note that the raid driver is attached with a raid card, so when the raid driver is not loaded successfully, you can either see the hard disk after entering the installation interface, or you can see an isolated hard disk instead of a raid hard disk, in this case, the installation process can be performed, but the same cannot be started after installation. After the raid driver is loaded successfully, go to the installation page, and you will see the size of the hard disk after raid settings, rather than isolated hard disks.
