== Install storcli under Ubuntu ==
== Overview ==


# Download the latest version of storecli from [https://www.broadcom.com/site-search?page=1&per_page=100&q=storcli&sort_direction&#x5B;pages&#x5D;=desc&sort_field&#x5B;pages&#x5D;=updated_at Broadcom URL] then unzip the zip file.
StorCLI는 Broadcom(구 LSI/Avago) MegaRAID 컨트롤러를 관리하기 위한 명령줄 도구입니다. MegaCLI의 후속 버전으로, 더 향상된 기능과 호환성을 제공합니다.
# Unzip will create folder name storcli_rel and this folder containes Unified_storcli_all_os.zip
# Again, unzip Unified_storcli_all_os.zip under the storcli_rel folder then it creates Unified_storcli_all_os folder which contains installable package to [[support]] various version of operating system.
# For Ubuntu, move to Unbuntu folder under the unzipped folder name Unified_storcli_all_os, e.g, Unified_storcli_all_os/Ubuntu
# Install Debian packages. By default, storcli64 executable file will be installed at  /opt/MegaRAID/storcli/storcli64
<syntaxhighlight lang="bash">
$ sudo dpkg -i storcli_rel/Unified_storcli_all_os/Ubuntu/*.deb  #example to install deb package


# To verify storcli installation
=== Summary ===
$dpkg -l | grep -i storecli


# Default storcli command will be installed at By default, storcli64 executable file will be installed at /opt/MegaRAID/storcli/storcli64
* 무엇인가? — MegaRAID 컨트롤러 관리 CLI 도구
* 왜 필요한가? — RAID 구성, 모니터링, 성능 최적화
* 언제 사용하는가? — 데이터센터 서버 RAID 관리


</syntaxhighlight>


* Administrator can add /opt/MegaRAID/storcli/storcli64 to $PATH or create symbolic link to exist $PATH such as /usr/local/bin
== Purpose ==


* HPCMATE storage system has symbolic link at /usr/loca/bin/storcli -> /opt/MegaRAID/storcli/storcli64
이 문서가 존재하는 이유


== Storcli vs Megacli ==
* Goal: StorCLI 설치, 명령어, RAID 구성, 모니터링 방법 제공
Although Storcli is '''successor of MegaCLI, StorCLI command syntax does not compatible with MegaCLI.'''  [https://www.broadcom.com/support/knowledgebase/1211161499760/lsi-command-line-interface-cross-reference-megacli-vs-twcli-vs-s this Broadcom page] '''describes the difference''' between MegaCLI and StorCLI
* Scope: StorCLI 설치, 명령어 요약, RAID 생성/삭제/확장, 핫 스페어 관리
* Non-goals: MegaCLI 레거시 명령어, 특정 OEM 펌웨어 설정은 별도 문서


== Storcli Commands ==

<u>** LSI recommend to use sequential access patterns in the range of 64 KB to 1 MB. Use random access patterns in the range of 0.5 KB to 8 KB</u> <ref>https://www.supermicro.com/CaseStudies/6Gbs_LSI_b.pdf</ref>
== Detailed Explanation ==


=== Deleting Virtual Drives ===
=== StorCLI 설치 (Ubuntu) ===
The following command deletes virtual drives:


storcli /cx/v(x|all) del [cc|cachecade]. (The cc or cachecade option to confirm that the deleted drive is a [[CacheCade drive]])
<syntaxhighlight lang="bash">
# 최신 버전 다운로드 (Broadcom 공식 URL)
# storcli_rel 폴더 생성
# Unified_storcli_all_os.zip 추출
# Ubuntu 폴더로 이동


=== Setting the disk cache policy in a Virtual Drive ===
# Debian 패키지 설치
To set the current disk cache policy on a virtual drive to on, off, or default setting.
$ sudo dpkg -i storcli_rel/Unified_storcli_all_os/Ubuntu/*.deb


storcli /cx/vx set pdcache=<on|off|default>
# 설치 확인
$ dpkg -l | grep -i storcli


Example) storcli /c0/v0 set pdcache=on
# 기본 설치 경로: /opt/MegaRAID/storcli/storcli64


# 심볼릭 링크 생성 (권장)
$ sudo ln -s /opt/MegaRAID/storcli/storcli64 /usr/local/bin/storcli
</syntaxhighlight>


<u>** LSI recommends Direct I/O for all RAID level configurations.</u><ref>https://www.supermicro.com/CaseStudies/6Gbs_LSI_b.pdf</ref>
=== StorCLI vs MegaCLI ===


=== Setting the read cache policy in a Virtual Drive ===
StorCLI는 MegaCLI의 후속 버전이지만, **명령어 구문이 호환되지 않습니다**. Broadcom의 크로스 레퍼런스 페이지에서 차이점을 확인할 수 있습니다.
To set the read cache policy on a virtual drive to read ahead, no read ahead, or adaptive read ahead.


storcli /cx/vx set rdcache=<ra|nora>
=== StorCLI 명령어 사용 ===


Example) storcli /c0/v0 set rdcache=nora
**StorCLI는 루트 권한으로 실행해야 합니다.** (권한 없으면 에러 없이 실패)


<syntaxhighlight lang="bash">
# 권한 없이 실행 (실패)
$ storcli show
Number of Controllers = 0


<u>** LSI does not recommend using the Always Read Ahead policy</u><ref>https://www.supermicro.com/CaseStudies/6Gbs_LSI_b.pdf</ref>
# 권한 있고 실행 (성공)
$ sudo storcli show
Number of Controllers = 1
</syntaxhighlight>


=== Setting the Write Policy in a Virtual Drive<ref>https://techdocs.broadcom.com/content/dam/broadcom/techdocs/data-center-solutions/tools/generated-pdfs/12Gbs-MegaRAID-Tri-Mode-Software.pdf</ref> ===

== Hot spare drives ==
* StorCLI는 항상 루트 권한으로 실행
A hot spare is an extra, unused drive that is part of the disk subsystem. It is usually in Standby mode, ready for service if a drive fails.
* Write Back + BBU/CacheVault 조합 사용 (성능 최적화)
* 핫 스페어 구성 (자동 복구)
* 정기적인 Consistency Check 실행
* Foreign Configuration 처리 (교체 서버 디스크)
* Direct Mode 활성화 (직접 연결 디스크)
* 디스크 직렬 번호 기록 (물리적 위치 추적)
* 정기적인 [[smartctl]] 모니터링


Hot spares let you replace failed drives without system shutdown or user intervention. The controller supports automatic and transparent rebuilds of failed drives using hot spare drives, which provide a high degree of fault tolerance and zero downtime.


The failed drive is removed from the virtual drive and marked ready awaiting removal after the rebuild to a hot spare begins. You can make hot spares of the drives that are not in a RAID virtual drive
== Limitations ==


=== Types of hot spare ===
* StorCLI는 MegaCLI와 명령어 호환 안됨
* RAID 00/10/50/60은 확장 불가
* Write Back은 BBU 필수 (데이터 손실 위험)
* StorCLI는 루트 권한 필요
* 일부 기능은 컨트롤러 모델에 따라 제한됨


* Global hot spare
* Dedicated hot spare

Detailed Explanation

StorCLI 설치 (Ubuntu)

# 최신 버전 다운로드 (Broadcom 공식 URL)
# storcli_rel 폴더 생성
# Unified_storcli_all_os.zip 추출
# Ubuntu 폴더로 이동

# Debian 패키지 설치
$ sudo dpkg -i storcli_rel/Unified_storcli_all_os/Ubuntu/*.deb

# 설치 확인
$ dpkg -l | grep -i storcli

# 기본 설치 경로: /opt/MegaRAID/storcli/storcli64

# 심볼릭 링크 생성 (권장)
$ sudo ln -s /opt/MegaRAID/storcli/storcli64 /usr/local/bin/storcli

StorCLI vs MegaCLI

StorCLI는 MegaCLI의 후속 버전이지만, **명령어 구문이 호환되지 않습니다**. Broadcom의 크로스 레퍼런스 페이지에서 차이점을 확인할 수 있습니다.

StorCLI 명령어 사용

    • StorCLI는 루트 권한으로 실행해야 합니다.** (권한 없으면 에러 없이 실패)
# 권한 없이 실행 (실패)
$ storcli show
Number of Controllers = 0

# 권한 있고 실행 (성공)
$ sudo storcli show
Number of Controllers = 1

시스템 개요

$ sudo storcli show

RAID 생성

# RAID6 생성 (6개 HDD)
$ sudo storcli /c0 add vd r6 name=RAID6 drives=0:0-5

# RAID1 생성 (OS용)
$ sudo storcli /c0 add vd type=raid1 drives=0:0-1 name=OS

# RAID10 생성
$ sudo storcli /c0 add vd type=raid10 drives=0:0-3 name=RAID10

# RAID5 생성
$ sudo storcli /c0 add vd type=raid5 drives=0:0-5 name=RAID5
    • RAID 생성 옵션:**
  • `strip=<8|16|32|64|128|256|512|1024>` — 스트라이프 크기
  • `pdcache=on|off|default` — 물리적 드라이브 캐시
  • `wt|wb` — Write Through/Back
  • `nora|ra` — Read Ahead
  • `Spares=[e:]s|[e:]s-x` — 핫 스페어

RAID 삭제

# 가상 드라이브 삭제
$ sudo storcli /c0/v0 del

# 모든 가상 드라이브 삭제
$ sudo storcli /c0/vall del

디스크 캐시 정책

# 가상 드라이브 캐시 정책 설정
$ sudo storcli /c0/v0 set pdcache=on
$ sudo storcli /c0/v0 set rdcache=nora
$ sudo storcli /c0/v0 set wrcache=wb
    • LSI 권장사항:**
  • 모든 RAID 레벨 → Direct I/O 권장
  • RAID 0/1/10 (스트리밍) → Write Through 권장
  • RAID 0/1/10 (랜덤) → Write Back 권장
  • RAID 5/6 → Write Back 권장

Write Policy

Write Policy Description Recommendation
Write Back (WB) 컨트롤러 캐시에 데이터 수신 시 완료 신호 "bursty" 쓰기 환경에 효율적
Write Through (WT) 드라이브에 데이터 수신 시 완료 신호 RAID 0/1/10 스트리밍 데이터에 권장
Always Write Back (AWB) BBU 부재 시에도 Write Back 강제 BBU 필수 (데이터 손실 위험)

디스크 정보 확인

# 사용 가능한 디스크 확인
$ sudo storcli /c0/eall/sall show

# 출력 예시
# EID:Slt DID State DG      Size Intf Med SED PI SeSz Model            Sp Type
# 0:0       4 UGood -  10.913 TB SAS  HDD N   N  512B HUH721212AL5200  U  -
    • 디스크 상태:**
  • UGood: Unconfigured Good
  • GHS: Global Hot Spare
  • DHS: Dedicated Hot Spare
  • Onln: Online
  • Fld: Failed

Foreign Configuration 처리

# Foreign Configuration 삭제
$ sudo storcli /c0/fall delete

# Foreign Configuration 확인
$ sudo storcli /c0/fall show

핫 스페어 관리

Type Description Example
Global Hot Spare 모든 RAID 그룹에 자동 할당 `storcli /cx/ex/sx add hotsparedrive`
Dedicated Hot Spare 특정 RAID 그룹에 할당 `storcli /cx/ex/sx add hotsparedrive dgs=N`
Emergency Hot Spare SMART 오류 시 자동 할당 `storcli /cx set eghs eug=on`
    • 핫 스페어 제거:**
# 핫 스페어 상태 제거
$ sudo storcli /c0/e65/s11 delete hotsparedrive

# 디스크 오프라인
$ sudo storcli /c0/e65/s11 set offline

디스크 위치 찾기

# 디스크 깜빡이기 (물리적 위치 확인)
$ sudo storcli /c0/e0/s2 start locate

# 깜빡임 중지
$ sudo storcli /c0/e0/s2 stop locate

디스크 교체

# 실패한 디스크 교체
$ sudo storcli /c0/e8/s0 insert dg=0 array=0 row=0

# 수동 리빌드 시작
$ sudo storcli /c0/e8/s0 start rebuild

디스크 직렬 번호 확인

$ sudo storcli /c0/eALL/sALL show all | egrep 'Device attributes|SN = '

디스크 상태 확인 (smartctl)

# 디바이스 ID 확인
$ sudo storcli /c0/eall/sall show

# smartctl로 디스크 테스트
$ smartctl -d megaraid,1 -a /dev/sda

Direct Mode vs Persistent Mode

Mode Description Use Case
Persistent (default) device IDs 변경 가능, expanders에 적합 기본값
Direct device IDs 고정, phy 번호와 일치 직접 연결 디스크 
# 현재 설정 확인
$ sudo storcli /c0 show directpdmapping

# Direct Mode 활성화
$ sudo storcli /c0 set directpdmapping=on

# Direct Mode 비활성화
$ sudo storcli /c0 set directpdmapping=off

RAID 확장

# 기존 RAID5에 디스크 추가
$ sudo storcli /c0/v0 start migrate type=raid5 option=add drives=8:0

※ RAID 00, 10, 50, 60은 이 방식으로 확장 불가
