Hp6000r server array fault

Today, an hp6000r server suddenly crashes and a red disk indicator in RAID 5 is displayed. Restarting the server and discovering the array self-check occurs when ID 2 is paused and the operating system cannot be started. Press Ctrl + m to enter the raid management tool. After the shutdown, all hard disks will be taken offline. At this time, the raid self-check is passed, the power is disconnected, and the hard disk will be inserted again. All hard disks will flash red, press Ctrl + M. after entering the raid management tool view, you will find that the information still exists. Fortunately, the hard disk that saves the raid information turns to a green light. The red light is still present, restart and enter the system ~~~~. Back up the data and transfer the host role (in case of a problem, redo the system easily ).
After logging on to the system, I backed up the system when RAID 5 lacked a hard disk. After lunch, I came back and found that there was another red light hard drive on RAID 5. It was so bad luck today. Fortunately, RAID5 data has been backed up early, restart system F2 into bios -- change disk controller from netraid to lvc scsi-> Save-> restart-> Ctrl + C-> select SCSI controller-> device selections-> select light red -> verify found that the bad hard disk in the morning has no bad track, in the afternoon, bad sectors may occur. Depressed ~~~~ -Restart after completion-> F2 to BIOS-> change disk controller from lvc scsi to netraid-> Save-> restart to Ctrl + M-> objects-> physical drive to solve the problem after the hard disk is forcibly launched, the startup server is normal. I don't know how long it will last ~~~. We hope we can stick to the New Year's Eve.
