오늘 지난번에 사용하던 HP DL120 G7 장비에 P212/256MB 레이드 설치를 했습니다 (IDC 엔지니어가)
그런데, P212가 Cache 없이 설치 되어 있다고 전화가 와서, 캐쉬만 끼우라고 했습니다.
굳이 같은 카드를 재설치할 필요는 없으니까요.

여기에서 고민이 생겼습니다.
오늘 받은 P212/256 카드에 배터리가 없었다는 것 입니다.
이 장비는 정비할 시간이 충분하기에 배터리의 장착은 영업을 통해 order를 하면 되는데
현재 사용중인 2CPU의 P212 Raid CARD에 배터리가 있는지 없는지 모른다는 것 입니다.
제가 설치한 것이 아니라서, 확인을 못 했습니다.

서버를 열지 않고 (가이드 없어 stack 해둬서 파워를 꺼야 합니다)
온라인에서 HP P212/256 Raid CARD의 배터리 장착여부를 확인 가능한 방법은 없을까요?

write cache를 커 놓은 상태라... 고민이 됩니다.
배터리 때문에 고민에 빠졌습니다.
배터리 없이 그냥 써도 될까요?
