UNIX - 특정 파일 시스템에 대한 물리적 장치 결정

AIX 7.2에서 발생할 수 있는 I/O 디스크 성능 문제를 해결하려는 경우:

$ oslevel -r
7200-05

$ oslevel
7.2.0.0

AIX 서버가 인터넷이나 로컬 저장소에 액세스할 수 없기 때문에 추가 패키지를 설치하지 않고 대상 장치(iostat)를 식별하는 방법을 이해하려고 합니다.

지금까지 배운 것:

pwd -P실제 디렉터리가 표시됩니다:

$ cd /etc/opt/legacy/module/conf/tmpdir

$ pwd
/etc/opt/legacy/module/conf/tmpdir

$ pwd -P
/tmp

df일치하는 파일 시스템이 표시됩니다.

$ df | grep "/tmp"
/dev/hd3        31457280  30641296    3%      189     1% /tmp

위 명령 출력의 결과는 다음과 같습니다./dev/hd3

iostat입력/출력이 표시됩니다.모두장비:

올바른 장치를 찾는 방법(하드 디스크), 대상 파일 시스템 호스팅: /dev/hd3?

추가 패키지를 설치하지 않고도 이를 달성할 수 있습니까?
