  • SYSCONFIG-A 在 1 个路径上显示较少的磁盘架:

使用 IOMB 的路径:

Shelf 3: DS224-12 Firmware rev. A: ---- IOM12B B: 0130

使用 IOMA 的路径:

Shelf 1: DS224-12 Firmware rev. IOM12B A: 0130 IOM12B B: 0130
Shelf 2: DS224-12 Firmware rev. IOM12B A: 0130 IOM12B B: 0130

  • SAS-EXPANDER-MAP 显示缺少一个磁盘架,并且在一条路径上缺少该磁盘架后连接的所有磁盘架都缺失。  在这种情况下,磁盘架 52 缺失。
