1. 軟件安裝
rpm -ivh Lib_Utils-1.00-09.noarch.rpm
rpm -ivh MegaCli-8.02.21-1.noarch.rpm
2. 常用命令
/opt/MegaRAID/MegaCli/MegaCli64 -AdpAllInfo -aALL //查看raid卡詳細信息
/opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo -aALL //查看raid和組成raid的磁盤
/opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL //查看raid
### //查看磁盤信息，精篩選
/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL|grep -Ei "(Enclosure Device|Slot Number|PD Type|Raw Size|Inquiry Data|Firmware state|ForeignState)"
- Adapter#0 -----raid卡控制器編號
- Enclosure Device ID: 64 -----外殼設備ID，也就是raid卡的ID號
- Slot Number: 6 ------磁盤槽位號
- PD Type: SAS ------磁盤類型
- Raw Size: 3.638 TB [0x1d1c0beb0 Sectors] ------大小
- Firmware state: Online, Spun Up ------磁盤狀態
查看磁盤狀態
/opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall|grep -E 'Slot\ Number|Firmware\ state'
查看磁盤是否有fail報錯
/opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall|grep -E 'Slot\ Number|Predictive\ Failure\ Count'
查看磁盤是否有error報錯
/opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall|grep -E 'Slot\ Number|Error\ Count'
定位故障盤VD
/opt/MegaRAID/MegaCli/MegaCli64 -ldpdinfo -a0|grep -Ei "(Target Id:|VirtualDrive:|RAID Level|^Size|Enclosure Device|Slot Number)"
定位故障盤盤符
ls -l /dev/disk/by-path
查看磁盤是否有外來配置
/opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall|grep -E 'Slot\ Number|Foreign\ State'
掃描RAID卡是否有外來配置
/opt/MegaRAID/MegaCli/MegaCli64 -CfgForeign -Scan a0
清除外來配置
/opt/MegaRAID/MegaCli/MegaCli64 -CfgForeign -Clear a0
報錯處理
Adapter 0: Configure Adapter Failed
FW error description:
The current operation is not allowed because the controller has data in cache for offline or missing virtual drives.
Exit Code: 0x54
處理： （6為硬盤ID數）
/opt/MegaRAID/MegaCli/MegaCli64 -DiscardPreservedCache -L6 a0
刪除陣列
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -L1 -a0 （1 為RIAD組Target Id號）
