问题描述

如果这会影响您的系统,请检查 Active IQ

每个 SAS 存储架堆栈最多可包含 10 个磁盘架,但以下情况除外:

  • FAS2040 ,每个堆栈限制为 4 个磁盘架
  • DS4486 磁盘架,每个堆栈最多 5 个
  • DS460C 磁盘架,每个堆栈限制为 4 个
  • 对于混合使用磁盘架的情况,限制为 240 个磁盘插槽或 10 个自身(首次命中限制适用)

10 个磁盘架限制仅适用于堆栈中的存储架数量,并且不是系统限制,因为系统可以包含多个堆栈。

如果系统中的单个堆栈包含 10 个以上的磁盘架、 EMS 中将显示以下警报:
<node_name>: dsa_disc: ses.config.shelfPopError:critical]: Disk shelf population on channel <XX> is ##. Reduce the number of disk shelves on this channel to 10 or fewer.
