连接到 SAS 端口 x 的电缆在降级模式下工作
适用于
- ONTAP 9
- SAS 存储架
- 系统采用多路径 HA 布线
问题描述
- ONTAP 事件消息系统示例：
[sas.cable.degraded:warning]: Cable attached to SAS port "0b" is functioning in a degraded mode
- ONTAP 事件日志显示输出示例：
::> event log show -event sas.cable*
Time Node Severity Event
---- --------- -------- ---------------------------
... node_name ERROR sas.cable.degraded: Cable attached to SAS port "0a" is functioning in a degraded
- ONTAP 系统运行状况降级示例：
::> system health subsystem show
Subsystem Health
----------------- ------------------
SAS-connect degraded
Environment ok
...
SAS-connect_Cluster ok
13 entries were displayed.
- 从 ONTAP CLI
sysconfig -a输出检查时，某些 PHY 的速度降低/禁用/速率未知。示例：
::> system node run -node <node_name> -command sysconfig -a
