This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Symptoms

  • Unisphere GUI 显示多个 DAE 驱动器的警报:
Unisphere GUI 显示多个 DAE 驱动器的警报
 
  • 在这一瞬间,由于后端连接环路,只连接了三个扩展柜,但显示有六个机柜。
  • 无法使用这些驱动器创建池,如果阵列已正常运行,则池将离线。
 

Cause

后端布线不正确。

连接有问题:
**如下所示,DPE SPA 上的 SAS 端口 1 连接到 LCC A 端口 “B”而不是端口“A”,而 DPE SPB SAS 端口 1 连接到最后一个 DAE 的 LCC B 端口“B”。这使得最后一个 DAE 同时连接为 1_0 和 0_2。哪个创建了一个循环?
连接有问题
 

Resolution

将连接更正为如下所示:
 
DAE 0_0 与 DPE 的连接:
DPE SP A SAS 端口 0 DAE 0_0 LCC A 端口 A
DPE SP B SAS 端口 0 DAE 0_0 LCC B 端口 A
DAE 1_0 与 DPE 的连接:
DPE SP A SAS 端口 1 DAE 1_0 LCC A 端口 A
DPE SP B SAS 端口 1 DAE 1_0 LCC B 端口 A
DAE 0_1 连接:
DAE 0_0 LCC A 端口 B DAE 0_1 LCC A 端口 A
DAE 0_0 LCC B 端口 B DAE 0_1 LCC B 端口 A

纠正连接

DPE - DAE 1_0

纠正连接

DPE — DAE 0_0
** 请记住,如果是 UnityXT 系列,则连接到 DPE 上的 SAS 端口 0 的第一个机柜为 0_0,如果是 Unity xxx/xxxF/x50 系列,则为 0_1。
纠正连接
DAE— DAE (0_1) 或 (1_1)
纠正连接
