1. Mega Radi tool 설치
web bios에서 Raid를 설정한 후 os로 부팅하여 megacli을 설치한다.
#wget http://mirror.nforce.com/pub/software/raidtools/Megaraid/8-07-14_MegaCLI.zip
#unzip 8-07-14_MegaCLI.zip
#cd Linux (운영체제에 맞게 선택한다.)
#rpm -ivh MegaCli-8.07.14-1.noarch.rpm
#ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/bin/megacli
(필요할 경우 다른 툴 storcli Raid tool 설치)
# tar xvfz 17.05.00.02_Linux-46_MSM.gz
# cd disk

RAID Level : 6 --> 레이드 번호
4.위 명령어로 확인 후 문제 발생 시 디스크 교체 및 재 장착 시도 후 자동으로 리빌딩 걸리는 지 확인해야 함.
#./MegaCli64 -AdpAutoRbld -Dsply -a0
Adapter 0: AutoRebuild is Disabled.
Exit Code: 0x00
# ./MegaCli64 -AdpAutoRbld -enbl -a0
Adapter 0: AutoRebuild is Enabled.
Exit Code: 0x00
5.위의 명령어로 자동 리빌딩을 걸었다면 실제 디스크를 배고 30초 혹은 1분뒤에 다시 꽂아서 자동 리빌딩 되는 지 확인 할 것.
만약 자동으로 리빌딜이 되지 않을 경우, 수동으로 진행해야 함.
# ./MegaCli64 -PDList -aALL |grep Firm

문제가있는 디스크의 순서를 잘 기억해야 한다.
위의 명령어 중에서 레이드 구성 정보를 확인할 때 부여되는 ID 값 252와 문제되는 슬롯의 번호를 아래와 같이 입력하여 디스크를 리빌딩할 수 있는 상태로 변경할 것.
# ./MegaCli64 -pdmakegood -physdrv [252:7] -a0
Adapter: 0: EnclId-252 SlotId-7 state changed to Unconfigured-Good.
Exit Code: 0x00
디스크 상태를 foreign 디스크 상태를 clear 할 것
# ./MegaCli64 -cfgforeign -clear -a0
Foreign configuration 0 is cleared on controller 0.
Exit Code: 0x00
디스크를 hot spare 설정하여 auto rebuild 진행할 것
# ./MegaCli64 -pdhsp -set -physdrv [252:7] -a0
Adapter: 0: Set Physical Drive at EnclId-252 SlotId-7 as Hot Spare Success.
Exit Code: 0x00
디스크가 리빌딩 되고 있는지 확인할 수 있는 명령어
# ./MegaCli64 -pdrbld -showprog -physdrv[252:7] -a0
Rebuild Progress on Device at Enclosure 252, Slot 7 Completed 0% in 0 Minutes.
Exit Code: 0x00
