# lsdev –C –s scsi
　　列出各个SCSI设备的所有相关信息：如逻辑单元号，硬件地址及设备文件名等。

　　# lslv –l datalv,lslv –p datalv
　　显示逻辑卷各种信息，如包含哪些盘，是否有镜像等。
　　八 网络故障定位方法
　　网络不通的诊断过程：
　　ifconfig 查看网卡是否启动 (up)
　　netstat –i 查看网卡状态
　　Ierrs/Ipkts 和 Oerrs/Opkts是否>1%

　　ping自己网卡地址 (ip 地址)
　　ping其它机器地址，如不通，在其机器上用diag检测网卡是否有问题。
　　在同一网中， subnetmask 应一致。
　　网络配置的基本方法：
　　(1) 如需修改网络地址、主机名等，一定要用 chdev 命令
　　# chdev –l inet0 –a hostname=myhost
　　# chdev -l en0 -a netadd
r=’9.3.240.58′ -a netmask=255.25
5.255.0’

　　(2) 查看网卡状态：# lsdev –Cc if
　　(3) 确认网络地址：# ifconfig en0
　　(4) 启动网卡：# ifconfig en0 up
　　(5) 配置路由
　　有两种方式加入路由：
　　永久路由
　　# chdev -l inet0 -a rout
e=’10.47.0.0’,’9.3.240.59’

　　临时路由
　　# route add 10.47.1.2 9.3.240.59
　　用命令 netstat -rn 查看路由表
