一个驱动器缺少路径,已被 IOM 绕过
适用于
- 报告“System has transitioned to a mixture of single path, multi-path and/or quad-path attached storage”
- 报告“DISK REDUNDANCY FAILED”
问题
- 磁盘缺少超过 1 个路径
cluster::> storage show disk -fields initiator
disk initiator

- 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
注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.
