问题

EMS 在降级模式下显示 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 的速度会降低或禁用。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

或

slot 0: SAS Host Adapter 0b (PMC-Sierra PM8070 rev. C, SAS, <UP>)
        Firmware rev:       03.08.09.00
        Base WWN:           5:00a098:003abb6:34
        Phy State:          [4] Disabled
                            [5] Enabled, 12.0 Gb/s
                            [6] Enabled, 12.0 Gb/s
                            [7] Enabled, 12.0 Gb/s

SAS 电缆重新拔插后，问题仍然存在。
"storage port show" 将 SAS 端口 0a 报告为 "online-degraded"
