如何从 dmesg 中的“ata*”获取“/dev/sd*”路径？

我有这个输出dmesg：

[149939.146576] ata18.00: exception Emask 0x1 SAct 0x0 SErr 0x0 action 0x0
[149939.146592] ata18.00: irq_stat 0x40000001

[156569.787624] ata18.00: status: { DRDY }

我想知道这个输出对应的块设备是什么

我尝试过查看/sys/block/*/device/scsi_device，/sys/block/*/device/scsi_disc但/sys/block/*/device/scsi_generic这些似乎是死路一条

如果我这样做，ls -dal /sys/class/ata_port/ata18/device/host* 我会得到这个：

drwxr-xr-x 5 root root 0 Jun 30 03:00 /sys/class/ata_port/ata18/device/host17

这似乎表明这个 ata 端口适用于主机 17

但如果我这样做，lsblk -S 我会得到这个：

NAME HCTL       TYPE VENDOR   MODEL             REV SERIAL         TRAN

sdh  11:0:0:0   disk ATA      ST8000VN004-2M21 SC60 ********       sata

这些都不是主机 17....我是不是漏掉了什么？有人能解释一下吗？谢谢

编辑：我正在考虑的一件事是离线阵列，然后逐个拉出驱动器并检查 dmesg，但要等待漫长的磁带备份过程先完成，这可能需要几天时间......

编辑：根据要求，我已包含 dmesg 过滤行：

“ATAPI: MARVELL VIRTUALL”看起来很可疑，不确定那是什么

答案1

尝试这个：

find /sys/class/ata_port/ata18/device/ -name block -exec ls {} +

或这个：

ls /sys/class/ata_port/ata18/device/host*/target*/*/block

我想您明白了。 ata18 上很可能没有块设备，在这种情况下sdX系统上就不会有块设备。 例如，那是 DVD 驱动器吗？

下面的内容也许能让你更好地了解这是什么：

find /sys/class/ata_port/ata18/device/ -name model -exec cat {} +

答案2

您可以使用 smartctl 快速检查所有磁盘。使用smartctl -H /dev/sdX或 获取更高级信息的示例smartctl -a /dev/sdX。

我想澄清一下您是否曾尝试过这样做ls -l /sys/block/sd*？
