nexenta 에서의 megacli 를 이용한 VD 생성(리부팅 필요없음)

[테스트 서버 준비]
192.168.30.10 => 테스트실

[테스트 전 준비]

MegaCLI.zip 다운받아서

unzip 해서 들어가서 solaris 것까지 푼다

[17:51:28][root@nhkobackup-001:~/tmp/MegaCLI-8.04.53/MegaCLI_Solaris]#pwd
/root/tmp/MegaCLI-8.04.53/MegaCLI_Solaris

[17:52:08][root@nhkobackup-001:~/tmp/MegaCLI-8.04.53/MegaCLI_Solaris]#ls
MegaCli MegaCli.pkg libstorelib.so

이렇게 나오면 chmod 700 ./MegaCli

해서 MegaCli 를 사용할 수 있다. 준비끝

==========================================================
[테스트]

1. PORT 7 번을 뺀다(장애상황 가정)

2. hot-spare 로 자동 리빌딩이 끝날때 까지 기다린다.(다 끝나면 아래와 같은 상태가 됨)
