Dell服务器MegaCli命令只返回Exit Code: 0x00问题分析

原文：http://my.oschina.net/guol/blog/169108

今天同事给我说一台dell的服务器做了raid后，使用MegaCli看不到raid信息，上去看了一下确实不返回任何raid信息，但是确实机器上做了raid。

   这就奇怪了，然后把MegaCli升级到最新版，还是同样的结果

    公司用的基本上都是dell系列的服务器，之前机器的raid信息都是MegaCli获取的，这几情况就有点怪异了。因为之前遇到过raid卡版本导致的其他问题，所以这次也怀疑是不是raid卡版本导致的问题，所以打算看看系统raid卡的版本信息

    没有找到raid信息，不过看了一下SCSI控制器的信息，根据SAS1068E上网一查，得出SAS1068E的raid卡是SAS 6i/R。

    为啥SAS 6i/R的raid信息用MegaCli64命令就获取不到呢，SAS 6/iR 只支持2块硬盘做raid0或者raid1。现在返回去看看MegaCli64工具，MegaCli64工具虽然非常好用，功能也很多，不仅能查看RAID卡信息，而且还能设置RAID卡，但是它却不支持SAS 6/iR的RAID卡，Dell好多1U型号的服务器默认的RAID控制器都是SAS 6i/R ，而对于这款控制器MegaCli64是不能使用的。那为什么MegaCli64不支持SAS 6i/R呢，因为megacli是为PERC控制器设计的(它使用的是大家熟悉的megaraid驱动)，但是SAS 6i/R控制器针对的是mpt*类型的驱动，所以MegaCli64取不出raid信息。不过想在命令行模式下想管理SAS 6i/R，可以使用Lsiutil这个工具。

下载lsiutil工具

解压后看到支持的系统还是蛮多的啊

  我是Linux 64位的系统，在linux目录下直接拷贝lsiutil.x86_64到目标机器上，修改为可执行权限。下面我们来看看lsiutil.x86_64怎么用，lsiutil.x86_64有两种模式，一种是交互式的，一种是命令行模式：

lsiutil.x86_64 交互式

lsiutil.x86_64 命令行式

  可以看到lsiutil.x86_64也是可以查看raid信息的。帮助文档如下：

如果你是debian/Ubuntu系统，则可以下载相应的deb包
