正如标题所示 - 我有一台新的 Dell R730xd，运行 Centos 6.7，并加载了所有更新等。我还安装了 Emulex 实用程序等。
问题是我尝试的任何方法（重新启动 / rescan-scsi-bus.sh / 手动）都无法使任何 LUNS 出现在操作系统中。除了 2 个本机 SCSI 驱动器外，我在 /dev/disk/by-path 中看不到任何内容。
hbacmd listhbas 的输出返回正常。
我在内核中收到了这些消息 - 但谷歌的研究表明它们是“无害的”（临终遗言）...各种 UP 和 Down 都是由于重新扫描而导致的（或看起来如此）...

首先 — — 我是 SAN 新手 — — 但我已经阅读了很多关于如何操作的文档 — — 但基本的只是看到 LUN 就让我感到困惑！
我刚刚安装了最新的 Emulex Linux 驱动程序 10.6.144.21，但这并没有解决或改变任何问题。
提前致谢！

答案1
解决了！SAN 人员绕过了 FC Fabric 交换机（我猜它肯定有一些奇怪的问题）——然后，一切都正常了，LUN 也出现了，等等。一切都很顺利。
因此，在某个时候我们必须弄清楚 FC Brocade 问题出了什么问题，但那是以后要解决的问题。
