Zabbix通过MegaCli实现对LSI Raid卡硬盘监控(LLD)

磁硬盘阵列后如何检测和监控硬盘健康状况？
查看有风险的盘
/opt/MegaRAID/MegaCli/MegaCli64 -LDPDinfo -A0 |grep "Device Id" |awk '{print $3}' |xargs -I {} smartctl -a -d megaraid,{} /dev/sdc |grep -Ei "^187|^188|^197|^198|Reallocated_Sector_Ct" | xargs -I{} echo {}

查看物理磁盘信息

#/opt/MegaRAID/MegaCli/MegaCli64 pdlist a0 

显示所有的物理信息

#/opt/MegaCli -PDList -aAll

a) lsiutil -p 1 -a 20,12,0,0 — 查看硬盘计数器
Invalid DWord Count 2,563 — 任何一个值大于0，都需要引起关注
Running Disparity Error Count 2,366
Loss of DWord Synch Count 0
Phy Reset Problem Count 0

c) lsiutil -p 1 -a 21,2,0,0,0 — 查看物理硬盘状态

编辑/etc/zabbix/zabbix_agentd.conf.d/disk.conf，添加自定义用户参数
