MegaCli操作1---創建與刪除raid

http://blog.sina.com.cn/s/blog_57c70e190101ebl9.html

今天給服務器DELL R710加硬盤，准備在線做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，免的日后忘記了。

 

用MegaCli做陣列，最重要是就是這三個系數：

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。

 

查看陣列卡信息

lspci -v

/opt/MegaRAID/MegaCli/MegaCli64 -AdpAllInfo -aALL

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 not found.

 

 

像我新增加的硬盤就是 [32:2] 

 

 

這里我的硬盤被標記為“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 appropriate attributes 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] WB Direct -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
