/N0/SB0/P3: Component Health Status of /N0/SB0/P3 is not OK.

lom>showsc <-检查SC版本，ScApp version: 5.19.6 Build_01，上solve.sun.com查看最近patch描述，居然有chs disabled的信息，先不管这么多，更新sc firmware到最新，故障依旧

没办法了只好向sun申请lom service模式密钥，值得注意的是申请所需信息的hostid不是showsc下显示的Chassis HostID，应该是lom>service命令提示下先输入空password而提示的HostID
