CentOS 8，戴尔PERC H330 RAID控制器，没有阻塞设备(大部分时间)

Question

我们最近购买了一台新的戴尔R340XL服务器，并安装了CentOS 8。我们在RAID 5(作为sdb)中有一个用于在BOSS控制器( sda)上引导的SSD和4个在H330上的HDDS。它工作了几天，当两天前，我们不能再看到袭击量。我们和戴尔通了电话，他们帮助我们升级了多台设备上的固件，但我们仍然看不到RAID的音量。任何帮助都将不胜感激。

当我这么做的时候，这个装置就会出现：

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

我下载了MegaCli，我可以得到各种各样的信息。命令MegaCli64 -LdGetNum -aAll告诉我如下：

Number of Virtual Drives Configured on Adapter 0: 1

如果我们一次又一次地重新启动服务器，偶尔会看到RAID数组显示为块设备，但它显示为sda，从而使引导驱动器sdb。

我查看了dmesg和系统日志，我不知道如何识别，但我确实看到了这样的情况：

这个分配失败看起来很值得关注，但是当我尝试搜索它时，我没有发现太多。一个人试图做200多个逻辑设备，但我们绝对不会在这里这样做。

提前谢谢。

Answer 1

再次检查它是否是一个H330，而不是一个HBA330；如果它真的是一个H330，检查是否有人意外地将它放入了HBA /pass身模式。希望是这样简单的事情，但我猜还有更多。
