**【问题复现步骤】**
1、设置所有磁盘设备自动挂起
[root@localhost ~]# echo auto > /sys/devices/pci0000:b4/0000:b4:02.0/host6/port-6:0/end_device-6:0/target6:0:0/6:0:0:0/power/control
[root@localhost ~]# echo 5000 > /sys/devices/pci0000:b4/0000:b4:02.0/host6/port-6:0/end_device-6:0/target6:0:0/6:0:0:0/power/autosuspend_delay_ms
...
[root@localhost ~]# echo auto > /sys/devices/pci0000:b4/0000:b4:02.0/host6/port-6:6/end_device-6:6/target6:0:6/6:0:6:0/power/control
[root@localhost ~]# echo 5000 > /sys/devices/pci0000:b4/0000:b4:02.0/host6/port-6:6/end_device-6:6/target6:0:6/6:0:6:0/power/autosuspend_delay_ms

2、设置SAS控制器自动挂起
[root@localhost ~]# echo auto > /sys/devices/pci0000:b4/0000:b4:02.0/power/control

3、查询SAS控制器及磁盘设备的挂起状态
[root@localhost ~]# cat /sys/devices/pci0000:b4/0000:b4:02.0/power/runtime_status
suspended
[root@localhost ~]# cat /sys/devices/pci0000:b4/0000:b4:02.0/host6/port-6:0/end_device-6:0/target6:0:0/6:0:0:0/power/runtime_status
suspended
[root@localhost ~]# cat /sys/devices/pci0000:b4/0000:b4:02.0/host6/port-6:6/end_device-6:6/target6:0:6/6:0:6:0/power/runtime_status
suspended

4、对SAS控制器触发PCI FLR
[root@localhost ~]# echo 1 > /sys/bus/pci/devices/0000:b4:02.0/reset

5、fdisk命令查询磁盘信息及数量
[root@localhost ~]# fdisk -l | grep sd | wc -l
2

**【实际结果】**
FLR命令执行完成后，环境的SATA磁盘设备不可用
