datalv,lslv –p datalv 顯示邏輯卷各種信息，如包含哪些盤，是否有鏡像等。 八 網絡故障定位方法 網絡不通的診斷過程： ifconfig 查看網卡是否啟動 (up) netstat –i 查看網卡狀態 Ierrs/Ipkts 和 Oerrs/Opkts是否>1% ping自己網卡地址 (ip 地址) ping其它機器地址，如不通，在其機器上用diag檢測網卡是否有問題。 在同一網中， subnetmask 應一致。 網絡配置的基本方法： (1) 如需修改網絡地址、主機名等，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) 查看網卡狀態：# lsdev –Cc if (3) 確認網絡地址：# ifconfig en0 (4) 啟動網卡：# ifconfig en0 up (5) 配置路由 有兩種方式加入路由： 永久路由 # chdev -l inet0 -a route=’10.47.0.0’,’9.3.240.59’ 臨時路由 # 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
