这是以前的一篇工作记录。印象中出问题时LED是0C31，但由于第二天就休年假了，3个星期后才上班，所以LED是否是0C31不太确定了。
Problem Title*: lft0 problem
Created Time: 2006-02-05
Probem Descrīption*: myaix-b是通过alt_disk方式clone的myaix-t(5200-05)，安装完成
后，通过显示器和键盘可以进入SMS（这说明显卡、显示器和键盘都是好的，且连接正常），但之后strarting AIX过程中显示器和键盘都无法使用，
TELNET也不可用。通过终端，lsdev -C |grep lft可以发现lft0状态为Defined。rmdev -dl lft0;
cfgmgr后lft0变为Available，此时显示器和键盘变为可用。但机器只要一重起就问题依旧。
