Two days ago, a Dell r720 installed rh5.1 for business needs. Both the Dell official website and the utilty disc support rh5.8 or above.
The hard disk cannot be found at the partitioning step when the disc is installed. That is to say, the ramdisk of the initrd of the disc does not have the driver of the RAID card,
The procedure is described as follows:

introduce the two servers (for the sake of convenience, we will record them as A and B, A as A power fault server, and B as A normal server ), two hard disks are used as raid 1 (two hard disks are backed up to each other). The raid card and machine configurations are the same,
The hard disk replacement solution is feasible only when such conditions are met. The specific replacement steps are as follows:
1. Unplug the two hard disks of machine A, shut down machine B, unplug the power cord, and i
