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

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
