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。
