适用场景

  • 报告"系统已过渡到单路径、多路径和/或四路径连接存储的混合存储"
  • 报告"磁盘冗余失败"

问题描述

  • 磁盘在1个路径上缺失

cluster::> storage show disk -fields initiator
disk initiator
------- -----------------------
1.30.19 3c,3d,3a,3b,3a,3c,3d,3b
1.30.20 3c,3d,3a,3b,3a,3c,3d,3b
1.30.21 3c,3d,3a,3b,3a,3c,3d,3b
1.30.22 3d,3a,3a,3d
1.30.23 3c,3d,3a,3b,3a,3c,3d,3b

  • 磁盘的SAS路径数低于预期 数量1 (以下为多路径HA布线的HA对):
cluster::*> storage disk show -fields model,path-count -path-count !4 
disk model path-count -------- ---------------- ---------- 1.30.22 X357_S16433T8ATE 2 

1 对于具有外部磁盘架的单节点(非HA)系统、具有纯内部磁盘的系统(例如AFF A200或FAS2700)或仅为单路径布线的系统、请将路径数更改为!2。同样、对于四路径布线系统(仅限IOM12)、将路径数更改为!8。

  • 磁盘缺少路径(nokeshell):
cluster::> node run -node * storage show disk -p 2 entries were acted on.
Node: cluster-n01 PRIMARY PORT SECONDARY PORT SHELF BAY -------- ---- --------- ---- --------- ... 0b.30.21 A 1c.30.21 B 30 21 0b.30.22 A 30 22 0b.30.23 A 1c.30.23 B 30 23 ...
  • 事件日志中报告了过多的无效DWORD错误

ds.sas.drivephy.disableErr:error]: Disk  [NETAPP :X477_HAKPE04TA0:NA0] S/N [XXXX] on channels 0b shelf ID 30 IOM B bay 22 Disabled due to excessive invalid dword error.
