如何將 /dev/sd 設備與它們所代表的硬體相關聯？

驅動器開始出現故障，我只能通過/dev/sdb設備文件名稱知道該設備。我可以使用哪些方法將該設備文件與實際硬體設備相關聯，以了解要物理替換哪個驅動器？

**獎勵：**如果我在此安裝中沒有/dev/disk/及其子目錄怎麼辦？（遺憾的是，我沒有）

您可以查看/sys/block：

-bash-3.2$ ls -ld /sys/block/sd*/device
lrwxrwxrwx 1 root root 0 Jun  8 21:09 /sys/block/sda/device -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0
lrwxrwxrwx 1 root root 0 Jun  8 21:10 /sys/block/sdb/device -> ../../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0
lrwxrwxrwx 1 root root 0 Jun  8 21:10 /sys/block/sdc/device -> ../../devices/pci0000:00/0000:00:1f.2/host2/target2:0:0/2:0:0:0
lrwxrwxrwx 1 root root 0 Jun  8 21:10 /sys/block/sdd/device -> ../../devices/pci0000:00/0000:00:1f.2/host3/target3:0:0/3:0:0:0

或者如果你沒有/sys，你可以看看/proc/scsi/scsi：

-bash-3.2$ cat /proc/scsi/scsi
