问题

  • 磁盘缺少超过 1 个路径

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 路径数少于预期数量1 (为多路径-HA连接的 HA 对如下所示):
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、具有仅内部磁盘的系统(例如 AFF A200 或 FAS2700)或仅为单路径连接的系统,将路径计数更改为 !2。同样,对于四路有线系统(仅 IOM12),将路径计数更改为 !8。

  • 磁盘缺少路径(nodeshell):
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.
