DSS7500：雙重故障和如何強制線上磁碟

• SI9361-8i RAID 卡
• 更換的磁碟28 
• Disk40 熱備援正在重新建置
• Disk22 處於離線狀態
• Disk40 重新建置失敗，因為來源驅動程式錯誤，有兩個硬碟故障，而且 VD 故障

1. 遠端檢查 disk22 HD 離線，disk28 HD 未設定良好 （遺失）
2. 當 disk22 離線且 VD0 故障時，RAID 卡記錄會檢查 VD0 降級

1. 嘗試強制將最後一個離線磁碟連線。如果磁碟連線，VD 可以恢復到降級狀態。
2. 在這種情況下，RAID 控制器 AVAGO MegaRAID 9361-8i 中的線上 disk22 人機介面基礎結構 （HII） 組態公用程式 以下步驟如下：
   1. 將伺服器重新開機。系統處於啟動狀態時，按下<F2>進入 「系統設定」。
   2. 按一下裝置設定，以存取控制器 AVAGO MegaRAID 9361-8i的管理功能表。使用方向鍵或滑鼠移動。

圖 5：磁碟機連接埠 0 - 3：01：22 離線

3. 選擇「磁碟機連接埠 0 - 3：01：22 硬碟」>作業 將磁碟機置於線上 > 確認作業 >正常。

4. 檢查 RAID 50 狀態是否復原為降級。

5. 從 RAID 控制器 AVAGO MegaRAID 9361-8i 管理軟體中，檢查 disk22 是否已連線，以及 disk40 是否正在重新建置。

3. 如果您必須更換磁碟，請檢查磁碟插槽資訊。
