106.6、通过脚本检测RAID 磁盘状态

107.Linux下脚本

108.#!

/bin/bash

109.#check raid disk status

110.MEGACLI="/opt/MegaRAID/MegaCli/MegaCli64 "

111.$MEGACLI -pdlist -aALL | grep "Firmware state" | awk -F :

'{print $2}' | awk -F , '{print $1}' >/tmp/fireware.log

112.$MEGACLI -pdlist -aALL | grep -E "Media Error|Other Error" | awk -F :

'{print $2}' >/tmp/disk.log

113.for i in `cat < /tmp/disk.log`

114.do

115.if [ $i -ne 0 ]

116. then

117.curl "http:

//xxxxxxB&state=ALARM&description=raid_disk_error"

118.fi

119.done

120.for i in `cat < /tmp/fireware.log`

121.do

122.if [ $i !

= Online ]

123. then

124.curl "http:

//xxxxxxstate=ALARM&description=raid_disk_offline"

125.fi

126.done

127.Windows 下脚本

128.Windows下脚本用的工具是gnu for windows平台的一些软件，如 bash grep awk cat

129.通过bash直接调用脚本

130.如：

\raid_check\unixtools>bash.exe G:

\disk.sh

131.#check raid disk status

132.MEGACLI="//G/raid_check/MegaCli.exe"

133.GREP="//G/raid_check/unixtools/grep.exe"

134.AWK="//G/raid_check/unixtools/awk.exe"

135.CAT="//G/raid_check/unixtools/cat.exe"

136.CURL="//G/raid_check/unixtools/curl.exe"

137.$MEGACLI -pdlist -aALL | $GREP "Firmware state" |$AWK -F:

'{print $2}' |$AWK -F , '{print $1}' >//c/fireware.log

138.$MEGACLI -pdlist -aALL | $GREP -E "Media Error|Other Error" | $AWK -F :

'{print $2}' > //c/disk.log

139.for i in `$CAT c:

/disk.log`

140.do

141.if [ $i -ne 0 ]

142. then

143.$CURL "http:

//xxxxxx&description=raid_disk_error"

144.fi

145.done

146.for i in `$CAT c:

/fireware.log`

147.do

148.if [ $i !

= Online ]

149. then

150.$CURL "http:

//xxxxx&state=ALARM&description=raid_disk_offline"

151.fi
