3. fp 포트 중 일부만 활성화

  : Hitach(HDLM), EMC(Powerpath) 등 스토리지 소프트웨어로 Multipath를 구성하는 경우 해당포트만 mpxio 구성해제 할 수 있다

 - fp.conf 위치 확인

  : fp.conf가 /kernel/drv 에 있는경우 해당 파일을 수정하고, /etc/driver/drv에도 있는경우 후순위 적용되므로 /etc/driver/drv 의 fp.conf를 수정한다

[root@SA-OCM3:~:#] find / -name fp.conf -exec ls {} \;

/etc/driver/drv/fp.conf

/kernel/drv/fp.conf

 - fp 포트 경로 확인
