我們最近購買了一台新的Dell R340XL 伺服器並安裝了CentOS 8。 。幾天前它運作良好，但兩天前，我們再也看不到 RAID 捲了。我們與戴爾通了電話，他們幫我們升級了多個裝置上的韌體，但我們仍然看不到 RAID 磁碟區。任何幫助將非常感激。
當我執行 lspci 時，該設備會顯示：
02:00.0 RAID bus controller: Broadcom / LSI MegaRAID SAS-3 3008 [Fury] (rev 02)
Subsystem: Dell PERC H330 Adapter
...
Kernel driver in use: megaraid_sas
Kernel modules: megaraid_sas
我下載了MegaCli，可以得到各種資訊。該命令MegaCli64 -LdGetNum -aAll告訴我這一點：
Number of Virtual Drives Configured on Adapter 0: 1
如果我們一遍又一遍地重新啟動伺服器，偶爾我們會看到 RAID 陣列顯示為區塊設備，但它顯示為 sda，從而使啟動磁碟機成為 sdb。
我查看了 dmesg 和系統日誌，我不知道如何識別，但我確實看到了這樣的事情：

分配失敗看起來令人擔憂，但當我嘗試用谷歌搜尋它時，我沒有找到太多。一個人試圖做超過 200 個邏輯設備，但我們絕對不會在這裡這樣做。
提前致謝。
答案1
仔細檢查它是 H330，而不是 HBA330；如果它確實是 H330，請檢查是否有人不小心將其置於 HBA/直通模式。希望是這樣簡單的事情，但我猜還有更多的事情。
