常用的系统状态查询命令# 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。

# ps -ef列出正在运行的所有进程的各种信息：如进程号及进程名等。

ps aux查看进程信息# netstat -rn列出网卡状态及路由信息等。

# netstat -in列出网卡状态及网络配置信息。

# df -k列出已加载的逻辑卷及其大小信息。

＃top查看系统应用信息，如CPU、内存使用率。

按u，输入用户名则可监视用户；按k然后输入特定进程PID可关闭此进程，输入信号代码15关闭进程，输入信号代码9强行关闭。

# mount列出已加载的逻辑卷及其加载位置。

# ntsysv选择启动服务# uname -a列出系统ID 号，系统名称，OS版本等信息。

# hostname列出系统网络名称。

# lsvg –l rootvg,lsvg –p rootvg显示逻辑卷组信息，如包含哪些物理盘及逻辑卷等。

# 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 netaddr='9.3.240.58' -a netmask=255.255.255.0’(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 route=’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 查看路由表附：常用命令列表：Any XXXX, ####, ****, or X is to be substituted
