注意,dwpri/dwstb/dwisd/dwied/bmdmk/dwbi/bistb对应的ip要放到hosts中

脚本发两个包去探测，基本上可以准确知道机器是否可达.

#more ping.sh#!/bin/sh

case "$1" in

dwpri|dwstb|dwisd|dwied|bmdmk|dwbi|bistb)#send 2 packets to pingif [ $1 = "dwpri" -o $1 = "dwstb" ];then nodeNUM=24elif [ $1 = "dwisd" -o $1 = "dwied" -o $1 = "bmdmk" ];then nodeNUM=8elif [ $1 = "dwbi" -o $1 = "bistb" ];then nodeNUM=4fi

pkgCNT=2

while [ $nodeNUM -gt 0 ];

do loss=`ping -c$pkgCNT $1${nodeNUM} |grep "loss"|awk '{print $6}'|awk -F% '{print $1}'` if [ $loss -eq "100" ];then echo $1$nodeNUM" is DOWN!" else echo $1$nodeNUM" is active" fi echo "===================$1${nodeNUM}==================="; (( nodeNUM -= 1 )); done;; *) echo "Usage: $0 {dwpri|dwstb|dwisd|dwied|bmdmk|dwbi|bistb}" exit 1 ;;esac
