从Sysconfig -a输出中报告磁盘架未知

适用场景

• FAS系统
• ONTAP 9
• DS2246磁盘架

问题描述

• 磁盘架状态通过HA对中两个节点上的一个适配器报告为未知：

::> system node run -node * sysconfig -a

Node-01

slot 0: SAS Host Adapter 0d (PMC-Sierra PM8001 rev. C, SAS, <UP>)
        Firmware rev:       01.12.09.00

      Shelf 27: DS2246  Firmware rev. IOM6 A: 0191  IOM6 B: 0191
      Shelf 28: DS2246  Firmware rev. IOM6 A: 0191  IOM6 B: 0191
      Shelf ?: unknown NUTAPP:DS224IOM6 

Node-02

slot 4: SAS Host Adapter 4c (PMC-Sierra PM8001 rev. C, SAS, <UP>)
      MFG Part Number:   USI 6086-000010-07 rev. MP V4.10
      
      Shelf 27: DS2246  Firmware rev. IOM6 A: 0191  IOM6 B: 0191
      Shelf 28: DS2246  Firmware rev. IOM6 A: 0191  IOM6 B: 0191
      Shelf ?: unknown NUTAPP:DS224IOM6 

• 正常情况下、另一个适配器会报告同一磁盘架：

::> system node run -node <node> sysconfig -a

slot 4: SAS Host Adapter 4a (PMC-Sierra PM8001 rev. C, SAS, <UP>)
      MFG Part Number:   USI 6086-000010-07 rev. MP V4.10
      
      Shelf 27: DS2246  Firmware rev. IOM6 A: 0191  IOM6 B: 0191
      Shelf 28: DS2246  Firmware rev. IOM6 A: 0191  IOM6 B: 0191
      Shelf 29: DS2246  Firmware rev. IOM6 A: 0191  IOM6 B: 0191

• 两个节点均通过适配器连接到一个通用IOM、该适配器会将磁盘架报告为未知：

::> system node run -node * -command sasadmin expander_map

Node-01

• 正常情况下会从两个适配器检测到磁盘。
• 事件日志中可能会报告以下事件：

[Node-01: dsa_disc: ses.shelf.unsupportAllowErr:alert]: Unsupported disk shelf found on channel 0d.

• 重新拔插受影响的IOM不能解决问题描述问题。
