Dell伺服器MegaCli命令只返回Exit Code: 0x00問題分析

標籤：

今天同事給我說一台dell的伺服器做了raid後，使用MegaCli看不到raid資訊，上去看了一下確實不返回任何raid資訊，但是確實機器上做了raid。

這就奇怪了，然後把MegaCli升級到最新版，還是同樣的結果

公司用的基本上都是dell系列的伺服器，之前機器的raid資訊都是MegaCli擷取的，這幾情況就有點怪異了。因為之前遇到過raid卡版本導致的其他問題，所以這次也懷疑是不是raid卡版本導致的問題，所以打算看看系統raid卡的版本資訊

沒有找到raid資訊，不過看了一下SCSI控制器的資訊，根據SAS1068E上網一查，得出SAS1068E的raid卡是SAS 6i/R。

為啥SAS 6i/R的raid資訊用MegaCli64命令就擷取不到呢，SAS 6/iR 只支援2塊硬碟做raid0或者raid1。現在返回去看看MegaCli64工具，MegaCli64工具雖然非常好用，功能也很多，不僅能查看RAID卡資訊，而且還能設定RAID卡，但是它卻不支援SAS 6/iR的RAID卡，Dell好多1U型號的伺服器預設的RAID控制器都是SAS 6i/R ，而對於這款控制器MegaCli64是不能使用的。那為什麼MegaCli64不支援SAS 6i/R呢，因為megacli是為PERC控制器設計的(它使用的是大家熟悉的megaraid驅動)，但是SAS 6i/R控制器針對的是mpt*類型的驅動，所以MegaCli64取不出raid資訊。不過想在命令列模式下想管理SAS 6i/R，可以使用Lsiutil這個工具。

解壓後看到支援的系統還是蠻多的啊

我是linux 64位的系統，在linux目錄下直接拷貝lsiutil.x86_64到目標機器上，修改為可執行許可權。下面我們來看看lsiutil.x86_64怎麼用，lsiutil.x86_64有兩種模式，一種是互動，一種是命令列模式：

lsiutil.x86_64 互動式

lsiutil.x86_64 命令列式

可以看到lsiutil.x86_64也是可以查看raid資訊的。協助文檔如下：

如果你是debian/ubuntu系統，則可以下載相應的deb包

wget ‘http://hwraid.le-vert.net/debian/pool-wheezy/lsiutil_1.60-1_amd64.deb‘dpkg -i lsiutil_1.60-1_amd64.deb

關於次問題的官方解釋如下：
