Respected Sir/Madam, I read ur howto about RAID 5 . I feel very happy. I have now some doubt. My system configuration :- 1) HP-NETSERVER LM3 400MHz dual processor,256MB RAM 4 *9.1GB = 36GB HARDDISK etc Problem 1 ) The server has an inbuilt HP RAID5 controller. When i enable this in the BIOS, i am unable to find out any SCSI drive in the system. When i disable this RAID5 option in the BIOS I can down load redhat 6.0 without nay problem. But i want to enable this inbuilt RAID5 that is inbuilt in the BIOS. PL tell me HOW to do that ? 2) In /etc/raidtab file what i have to write :- I create three partition in first harddisk like sda1--linux native ,sda2--swap ,sda3---/usr1 REST are /dev/sdb1, /dev/sdc1,/dev/sdd1 only . My root is in sda1 and rest are free. Pl. tell me what i have to write. I have confusion that /dev/sda3 will come in array or not . Pl give me all these information. I will be very thankfull to u.
