1、前言
新採購的 Dell R310 配備的 RAID Card 為 PERC H200，使用此工具後可以在文字模式 (Command Line) 下很方便的查看目前 RAID 及 HDD 狀態。文章目錄
1、前言2、實作環境
3、安裝及設定
步驟1.下載 sas2ircu
步驟2.給予執行檔案權限
步驟3.了解 RAID 顯示狀態相關名詞
步驟4.了解 RAID 運作中、損壞、重建 狀態
4、參考
2、實作環境
- CentOS 6.2 (64 位元) 2.6.32-220.el6.x86_64
- 伺服器硬體型號： Dell PowerEdge R310
- 硬碟規格： SATA III HDD 500GB * 2 (Build RAID-1)
- 磁碟陣列卡型號： Dell PERC H200A Adapter RAID Controller
- mpt2sas0: Dell PERC H200 Adapter
- sas2ircu： FAQ_9633_SAS2IRCU_Phase_5.0-5.00.00.00.zip
3、安裝及設定
在開始進行設定以前，再次確認一下目前的 RAID Card 是否為此型號。# lspci -nn |grep LSI
05:00.0 Serial Attached SCSI controller [0107]: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] [1000:0072] (rev 03)步驟 1. 下載 sas2ircu
至 Supermicro 下載中心 下載 FAQ_9633_SAS2IRCU_Phase_5.0-5.00.00.00.zip。# wget http://www.supermicro.com/support/faqs/data_lib/FAQ_9633_SAS2IRCU_Phase_5.0-5.00.00.00.zip下載完成後進行解壓縮的動作，此壓縮檔案中包含各種作業系統適用的執行檔如 DOS、Linux、Solaris、Windows ...等。

解壓縮後的檔案可立即使用，但是預設檔案權限為 444 因此必須給予執行權限，並且複製到系統執行目錄下以便執行。# cd sas2ircu_linux_x86_rel //切換到 Linux 執行檔存放目錄
# chmod 755 sas2ircu //給予檔案執行權限
# cp sas2ircu /usr/local/sbin/ //複製到系統執行目錄下
# sas2ircu LIST //查看 RAID 資訊

SAS2IRCU: Utility Completed Successfully.步驟 3. 了解 RAID 顯示狀態相關名詞
在開始使用 sas2ircu 之前有些名詞我們必須先了解，這樣之後觀看上才不致有困惑的情況發生。IR Volume： 虛擬硬碟，多顆硬碟組合起來的虛擬硬碟，簡單說就是 RAID
- Okay： RAID 目前狀態為 正常 (最優)
- Degraded： RAID 目前狀態為 不正常 (退化、降級)
Physical device： 實體硬碟，簡單說就是主機上有幾顆硬碟
- Optimal： 實體硬碟目前狀態為 正常
- Missing： 實體硬碟目前狀態為 不正常 (失敗、未設定)
- Rebuilding： 實體硬碟目前狀態為 重建中
以下表格為當主機硬碟正常時、發生損壞時其 VD 及 PD 的狀態
步驟 4. 了解 RAID 運作中、損壞、重建 狀態
當 RAID 運作正常時 執行結果如下，可看到 IR Volume 狀態為 Okay，而 Physical device (有 2 顆) 狀態為 Optimal。# sas2ircu 0 DISPLAY //查詢詳細資訊
