常用的系统状态查询命令

 

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。

# 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。

# mount

列出已加载的逻辑卷及其加载位置。

# 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。

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)

netstati查看网卡状态

Ierrs/IpktsOerrs/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:# lsdevCc 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 add10.47.1.2 9.3.240.59

用命令netstat -rn查看路由表
