问题描述

SAS端口显示琥珀色LED
中的SAS端口PHY已禁用警报 system health alert show。

Clutser1::> system health alert show Node: Node1 Resource: Port 0b Severity: Major Indication Time: Fri Jan 03 01:07:42 2020 Suppress: false Acknowledge: false Probable Cause: SAS port 0b on controller Node1 has 1 disabled PHYs. Possible Effect: Inactive PHYs might cause degraded link performance. Corrective Actions: 1. Verify that SAS port 0b has disabled PHYs by using the "storage port show -node Node1 -port 0b" command. 2. If the disk shelves connected to port 0b have multiple path to the node, reset port 0b by using the (privilege: advanced) "storage port reset -node Node1 -port 0b" command. 3. Verify that the physical cable connection is secure and operational. If the disk shelves are multipathed, reseat the cable. 4. If the connected disk shelf is multipathed, replace the SAS cable.

已在中禁用PHY sysconfig -a。
