[HP-UX] Ioscan 으로 HW 멀티패스 확인할때 사용하는 명령어

IOSCAN 명령어를 사용하면 다양하게 확인할 수 있는 것이 많다 그 중 하나가 이런 DISK 실장한 여부를 확인하는데

이 HP-UX의 경우에는 그것을 확인하기 위해서 몇 가지가 필요핟.

특히 멀티 PATH인 경우에는 말이다.

아래 내용은 MAN 페이지에서 멀티패스로 잡혀있는 DISK를 보기 위해 어떤 내용이 필요한지 그 내용을 첨삭해서 긁어 붙여 보았다.

      hw path          A numerical string of hardware components, notated
                       sequentially from the bus address to the device
                       address.  Typically, the initial number is appended
                       by slash (/), to represent a bus converter (if
                       required by your machine), and subsequent numbers are
                       separated by periods (.).  Each number represents the
                       location of a hardware component on the path to the
                       device.

      Display the mapping between legacy device special file and persistent
      device special file.
