shell实现hp刀片ilo地址配置

一、问题背景

HP刀片在使用KVM远程console管理过程中，要求刀片配置的ILO地址和HP OA地址在同一网段。由于IP地址资源紧张，刀筐OA口默认配置上了地址，刀片没有配置，都是使用的时候临时配置。所以一旦物理机出现问题，想要通过远程管理口查看主机所处的状态就比较麻烦。先要通过ping工具查询预留地址是否可用。再在OA界面上进行配置，比较影响效率。

二、脚本实现

该脚本写的比较凑合，杂糅了shell、C语言、expect 三者实现的，具体代码如下：

#!/bin/bash
#code from www.361way.com
#auto set the Blade ilo address
usage( )
{
  echo "usage: $0 oaip username  password"
}
if [ $# -lt 3 ]; then
   usage
   exit 1
fi
oaip=$1
username=$2
password=$3
oaip=`sshpass -p$password  ssh -o StrictHostKeyChecking=no     $username@$oaip "SHOW OA NETWORK" |grep 'IPv4 Address:'|awk '{print $3}'`
oamask=`sshpass -p$password  ssh -o StrictHostKeyChecking=no   $username@$oaip "SHOW OA NETWORK" |grep 'Netmask:'|awk '{print $2}'`
oagate=`sshpass -p$password  ssh -o StrictHostKeyChecking=no   $username@$oaip "SHOW OA NETWORK" |grep 'Gateway Address:'|awk '{print $3}'`
clear
echo -e '\n\n'
echo '****************************'
echo  'The Blade box information:'
echo '****************************'
echo  IP ADDR:  $oaip
echo  NETMASK:  $oamask
echo  GATEway:  $oagate
mask2cdr ( )
{
   # Assumes there's no "255." after a non-255 byte in the mask
   local x=${1##*255.}
   set -- 0^^^128^192^224^240^248^252^254^ $(( (${#1} - ${#x})*2 )) ${x%%.*}
   x=${1%%$3*}
   echo $(( $2 + (${#x}/4) ))
}
cdr2mask ( )
{
   # Number of args to shift, 255..255, first non-255 byte, zeroes
   set -- $(( 5 - ($1 / 8) )) 255 255 255 255 $(( (255 << (8 - ($1 % 8))) & 255 )) 0 0 0
   [ $1 -gt 1 ] && shift $1 || shift
   echo ${1-0}.${2-0}.${3-0}.${4-0}
}
addcdr=$oaip/`mask2cdr $oamask`
echo -e '\n\n'
echo '******************************'
echo   We will scan the network
echo   And get can use ip now
echo   Please wait a moment!!!
echo '******************************'
fping -g $(echo `./net2ip  $addcdr`)|grep 'unreachable'
read -p "Enter can used ip for blade: " iloip
read -p "Enter the blade bay id: " bid
setip="set ebipa server $iloip $oamask  $bid"
setgate="set ebipa server gateway $oagate  $bid"
cat>autoexec.exp<<EOF
#!/usr/bin/expect
spawn ssh $username@$oaip
expect {
    "(yes/no)?" {
        send "yes\n"
        expect "assword:"
        send "$password\n"
    }
        "assword:" {
        send "$password\n"
    }
}
expect "*>"
send "set ebipa server $iloip $oamask  $bid\n"
expect "*bays?"
send "YES\n"
expect "*>"
send "set ebipa server gateway $oagate  $bid\n"
sleep 2
expect "*?"
send "YES\n"
expect eof
#interact
EOF
expect -f autoexec.exp

凑合着功能实现了，后面有时间统一使用python再实现下。
