使用MegaCli監控H700 Raid卡磁盤

使用過程當中發現有多個Virtual Drive存在的問題，所以在上一個版本上作了改進。

# zabbix_agentd userparams配置
$ cat zabbix_agentd.userparams.conf
UserParameter=raid.h700[*],/usr/local/etc/scripts/check_h700_status_plus.py $1

# zabbix_server調用
$ zabbix_get -s 192.168.10.100 -k raid.h700['State']
Virtual Drive:0 Code:0 Info:Optimal
Virtual Drive:1 Code:0 Info:Optimal
$ zabbix_get -s 192.168.10.100 -k raid.h700['Cache']
Virtual Drive:0 Code:0 Info:WriteBack
Virtual Drive:1 Code:0 Info:WriteBack
