通过脚本检测RAID 磁盘状态
Linux下脚本
#!/bin/bash
#check raid disk status
MEGACLI="/opt/MegaRAID/MegaCli/MegaCli64 "
$MEGACLI -pdlist -aALL | grep "Firmware state" | awk -F : '{print $2}' | awk -F , '{print $1}' >/tmp/fireware.log
$MEGACLI -pdlist -aALL | grep -E "Media Error|Other Error" | awk -F : '{print $2}' >/tmp/disk.log
for i in `cat do
if [ $i -ne 0 ]
then
curl "http://xxxxxxB&state=ALARM&description=raid_disk_error"
fi
done
for i in `cat do
if [ $i != Online ]
then
curl "http://xxxxxxstate=ALARM&description=raid_disk_offline"
fi
done
Windows 下脚本
Windows下脚本用的工具是gnu for windows平台的一些软件，如 bash grep awk cat
通过bash直接调用脚本
如：G:\raid_check\unixtools>bash.exe G:\disk.sh
#check raid disk status
MEGACLI="//G/raid_check/MegaCli.exe"
GREP="//G/raid_check/unixtools/grep.exe"
AWK="//G/raid_check/unixtools/awk.exe"
CAT="//G/raid_check/unixtools/cat.exe"
CURL="//G/raid_check/unixtools/curl.exe"
$MEGACLI -pdlist -aALL | $GREP "Firmware state" |$AWK -F: '{print $2}' |$AWK -F , '{print $1}' >//c/fireware.log
$MEGACLI -pdlist -aALL | $GREP -E "Media Error|Other Error" | $AWK -F : '{print $2}' > //c/disk.log
for i in `$CAT c:/disk.log`
do
if [ $i -ne 0 ]
then
$CURL "http://xxxxxx&description=raid_disk_error"
fi
done
for i in `$CAT c:/fireware.log`
do
if [ $i != Online ]
then
$CURL "http://xxxxx&state=ALARM&description=raid_disk_offline"
fi
