We have a HP DL380 G5 server with Centos 5.0 on it with hardware raid 5, as one of the disk has failed and spare disk has taken over it's place so we don't have any spare disk in the array. I want to add the spare disk in the array and i want your valuable suggestion how to do that. The machine has 3 SCSI hot pluggable drives.
I know the utility is hpacucli but dont know how to add the disk in the raid. This is my first time i am doing it and server is Live with some critical application.
if any one can let me know steps to add the spare disk including if we need to format the disk with ext3 file system before or after adding the disk.
