- 存储HBA端口仍以物理方式连接
尝试隔离问题描述的以下故障诊断步骤：
- 已 使用以下命令验证远程SFP的运行状况并已退回端口：
Cisco示例：
switch# config terminal
switch(config)# interface fc <slot>/<port#>
switch(config)# show int fc <slot>/<port#> transceiver detail
switch(config-if)# shutdown
switch(config-if)# no shutdown
Brocade示例：
switch:admin> sfpshow <index # OR slot/port #>
switch:admin> portdisable <index # OR slot/port #>
switch:admin> portenable <index # OR slot/port #>
- 已执行物理检查并重新安装连杆和 配线板部件。
- 重新安装后、重复端口弹跳过程。
- 更换/交换两端的组件、包括缆线和SFP。
