DELL服务器硬件信息采集SHELL脚本

最近需要做资产列表，要采集DELL服务器的硬件信息，包括如下信息：

1、操作系统信息（类型，版本，内核，平台，主机名）

2、主板信息（厂商，机型，序列号）

3、CPU信息（型号，个数，物理核数）

4、内存（条数，单条容量）

5、磁盘（个数，单个容量，磁盘类型，Raid级别）

 执行前请先安装MegaRAID，为了提高工作效率，我们使用SHELL脚本来实现，如下：

#!/bin/sh #get os information function get_os_info() {    release=`cat /etc/redhat-release | awk '{print $1"_"$3}'`    kname=`uname -s`    nodename=`uname -n`    kernal=`uname -r`    bit=`uname -i`    printf "OS_RELEASE: $release"_"$bit\n"    printf "OS_DETAIL: $kname $nodename $kernal $bit\n"} get_os_info #get vendor, model, sn... function motherboard() {    vendor=`dmidecode -t 1|grep "Manufacturer"|awk '{print $2}'`    model=`dmidecode -t 1|grep "Product"|awk '{print $4}'`    sn=`dmidecode -t 1|grep "Serial" |awk '{print $3}'`    printf "MODEL: $vendor $model\n"    printf "SN: $sn\n"} motherboard function memory() {    count=`dmidecode  -q -t 17 2 |grep  "Size" |grep -v "No Module Installed"|awk '{print $2}'|uniq -c|awk '{print $1}'`    capacity=`dmidecode  -q -t 17 2 |grep  "Size" |grep -v "No Module Installed"|awk '{print $2}'|uniq -c|awk '{print $2}'`    capacity=`expr $capacity / 1024`    printf "MEM: $count"*"$capacity"G"\n"} memory function cpuinfo() {    cpu_model=`cat /proc/cpuinfo|grep "model name"|head -1|awk -F: '{print $2}'`    cpu_count=`cat /proc/cpuinfo|grep "core id"|grep "0"|uniq -c|awk '{print $1}'`    cpu_total_cores=`cat /proc/cpuinfo|grep "processor"|wc -l`    single_cores=`expr $cpu_total_cores / $cpu_count`    printf "CPU:$cpu_model($cpu_count"*"$single_cores"Cores")\n"} cpuinfo function diskinfo() {    raidlevel=`/opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL |grep "RAID"|awk '{print $3}'|cut -b 9-9`    disknumber=`/opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL | grep "Drives"|awk -F ":" '{print $2}'`    disktype=`/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | grep "PD Type"|head -1|awk -F: '{print $2}'`    diskcapacity=`/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | grep "Raw Size" | head -1 | awk '{print $3}'`    printf "DISK: $disknumber"*"$diskcapacity"GB"$disktype (Raid Level: $raidlevel)\n"} diskinfo
