솔라리스에서 디스크 추가

1. 솔라리스 디스크 추가 절차

 

touch /reconfigure로 시스템이 새로 추가한 디스크를 인식하도록 함
  ↓
init 5
  ↓
디스크 추가
  ↓
부팅

  ↓
fdisk로 솔라리스 시스템 전체 할당
  ↓
partition으로 각 슬라이스마다 용량 할당
  ↓
newfs로 파일시스템 포맷(기본 ufs)
  ↓
mount로 슬라이스와 마운팅포인트를 마운트
  ↓
vi /etc/vfstab에 내용을 추가하여 자동 마운트 되도록 설정

 

 

 

2. 솔라리스 디스크 추가 방법

 

# touch /reconfigure  / 에 reconfigure(빈 파일) 생성

# init 5  서버 셧다운 후 -> 하드 디스크 장착 후 -> 서버 파워 온

# prtconf  현재 시스템 장치의 구성 상황을 알기 위해서 사용하는 명령어

 

 

※ 참고

init S 단일 사용자 모드로 본쉘만 실행된 상태, 필수 파일 시스템만 마운트 된다.
init 0 시스템을 종료하고 부트 PROM 의 ok 프롬프트 상태가 된다.
init 1 단일 사용자 모드와 같으나,                  모든  파일 시스템이 마운트 된다.
init 2 다중 사용자 모드로 NFS서버 데몬 제외, 일반적인 데몬은 모두 수행된다.
init 3 런 레벨2 와 같으나 NFS 서버 데몬까지 실행된 상태
init 4 미사용
init 5 시스템 종료
init 6 시스템 종료, 재부팅

 

# format format 명령어를 이용해서 현재 시스템에 부착된 디스크를 확인

가. c #  t #  d #  s #

c : controller name , c0, c1, c2,  보통 SCSI 카드의 번호

t  : target number, t0, t1, t2, SCSI 카드의 케이블 연결 번호

d : disk number, d0, d1, d2  : SCSI 카드의 target에 디스크 젠더 등을 통해 연결할 때의 번호

s : slice number, s0, s1, s2,  디스크의 슬라이스 번호

 

※ 참고

1. 솔라리스의 슬라이스(slice)는 리눅스의 파티션과 같은 개념
2. x86 시스템에서 IDE 디스크를 장착할 때에는 target 번호는 생략
