서버에서 lspath 로 확인해 보면, 간혹 Path miss 상태 확인이 된다.
이때, path 가 몇개 안되면 rmpath 명령어로 간단하게 하면 되지만,,,,,,Paths가 많은경우, 스크립트를 사용하면 편리하다 (4.항목 참조)
EX) 스토리지에서는 FC-Port degreded 상태확인 및 OS 에서는 lspath 상태에서 일부 path miss 상태확인
1) 스토리지 FC Port 확인
2) 서버 HBA 확인
#root > lsdev -Cc adapter |grep fcs |awk '{print "lscfg -vpl" $1 "|grep -i Network"}' |sh -v
lscfg -vplfcs0|grep -i Network
Network Address.............10000000C9943560 / degraded
lscfg -vplfcs1|grep -i Network
Network Address.............10000000C9943561
lscfg -vplfcs2|grep -i Network
Network Address.............10000000C99434AC / degraded
lscfg -vplfcs3|grep -i Network
Network Address.............10000000C99434AD
lscfg -vplfcs4|grep -i Network
Network Address.............10000000C97DB21C
lscfg -vplfcs5|grep -i Network
Network Address.............10000000C97DB21D
3) 누락경로 확인
#root:/ > lspath |grep -i missing
Missing hdisk4 fscsi2
Missing hdisk5 fscsi2
Missing hdisk6 fscsi2
Missing hdisk7 fscsi2
Missing hdisk8 fscsi2
Missing hdisk4 fscsi0
Missing hdisk5 fscsi0
Missing hdisk6 fscsi0
Missing hdisk7 fscsi0
Missing hdisk8 fscsi0
3-1) 각 hdiskx 기준으로 2개의 누락경로 확인

4) 스크립트 작성
이 스크립트는 시스템의 모든 디스크 목록을 제공함.
그런 다음이 목록을 사용하여 스크립트는 각 디스크를 구문 분석하여 lspath 명령으로 반복하여
누락 된 경로 목록을 출력한다.
awk를 사용하여 갭을 메꾸어 rmpath 명령에 대한 올바른 구문을 생성.
출력은 제거 할 경로가 들어있는 xrmpaths 파일을 생성함.
[Script] 예시
#!/bin/sh
# rmpaths
>xrmpaths
echo "#!/bin/sh" >>xrmpaths
disks=$(lspv | awk '{print $1}')
for loop in $disks
do
lspath -l $loop -H -F "name:parent:connection:status" |grep Missing| awk -F: '{print "rmpath -dl",$1,"-p", $2, "-w", $3}'>>xrmpaths
done
