   Á¶È¸ 44958   Ãßõ 1    

최근 버젼의 firmware로 업그레이드를 해도 read/write ratio의 변경이 안되고
hpacucli에서 cache ratio의 변경이 안되는 것에 대해서
구글링을 해도 마땅한 답이 없습니다.
 
# hpacucli

Type "exit" to close the console.
=> ctrl slot=1 modify cacheratio=50/50
Error: "cacheratio=50/50" is not a valid option for Smart Array P410 in Slot 1
   There are no options currently available.
 
원인은 배터리가 없어서. 그런데, FBWC라서... 배터리는 큰 의미가없는데...
