问题描述

EMS 显示处于降级模式的SAS端口。

[sas.cable.degraded:error]: Cable attached to SAS port "0a" is functioning in a degraded mode.

从 sysconfig -a 输出中检查时、某些PHY的速度会降低。示例：

slot 0: SAS Host Adapter 0a (PMC-Sierra PM8072 rev. C, SAS, <UP>) Firmware rev: 03.08.09.00 Base WWN: 5:00a098:00f5e56:b0 Temperature: Not Available Phy State: [0] Enabled, 6.0 Gb/s [1] Enabled, 12.0 Gb/s [2] Enabled, 3.0 Gb/s [3] Enabled, 12.0 Gb/s

重新拔插SAS电缆后、问题描述仍然存在。
