MegaCli操作1---創建與刪除raid0

今天給服務器DELLR710加硬盤，準備在線做raid，以前不太注意這些事，搞起來花了一些時間，不過還好是搞定了，趕緊記錄下來，免的日後忘記了。

用MegaCli做陣列，最重要是就是這三個係數：

Adapter #0

Enclosure Device ID: 32

Slot Number: 0

分別代表了 -PhysDrv[E0:S0,E1:S1,...] -aN #物理磁盤的enclosure號:slot號  -a是陣列卡號

這些參數可以通過下面的命令得到。

查看所有物理硬盤狀態

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -a0

# /opt/MegaRAID/MegaCli/MegaCli64 help |grep -i pdinfo

MegaCli -pdInfo -PhysDrv[E0:S0,E1:S1,...] -aN|-a0,1,2|-aALL

MegaCli -LdPdInfo -aN|-a0,1,2|-aALL

查看邏輯盤詳細信息

# /opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo-aALL

查看單個盤的詳細信息

# /opt/MegaRAID/MegaCli/MegaCli64 -pdInfo -PhysDrv[32:3] -aALL

Adapter 0: Device at Enclosure - 32, Slot - 3 is notfound.

像我新增加的硬盤就是 [32:2]

這裏我的硬盤被標記爲“Foreign”外來配置，要清除一下，不然會報下面這個錯誤：

The specified physical disk does not have the appropriateattributes to complete

the requested command.

Exit Code: 0x26

掃描外來配置的個數：

# /opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -scan -a0

There are 1 foreign configuration(s) on controller 0.

Exit Code: 0x00

清除外來配置：

# /opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -clear -a0

Foreign configuration 0 is cleared on controller 0.

Exit Code: 0x00

再次掃描外來配置的個數：

# /opt/MegaRAID/MegaCli/MegaCli64 -cfgforeign -scan-a0

There is no foreign configuration on controller 0.

Exit Code: 0x00

創建Raid0

# /opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0[32:2] WBDirect -a0

Adapter 0: Created VD 2

Adapter 0: Configured the Adapter!!

Exit Code: 0x00

刪除陣列：

# /opt/MegaRAID/MegaCli/MegaCli6  -cfgclr -a0   清除所有的raid組的配置

# /opt/MegaRAID/MegaCli/MegaCli6  -cfglddel -L0 -a0  刪除指定的raid組(Target Id:0)的raid組，可以通過上面的“查看邏輯盤詳細信息”得到。

查看硬盤的重建情況：
# /opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ProgDsply -PhysDrv[12:7] -aALL
Device(Encl-12 Slot-7) is not in rebuild process
