linux scsi物理拓扑

有没有什么办法可以在linux的SCSI总线上find驱动器的物理拓扑结构？

这里是一个例子：

>: for drive in $(find /dev/disk/by-path -name \*0|sort); do udevadm info --query=path --name $drive ; done /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:0/0:2:0:0/block/sda /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:1/0:2:1:0/block/sdb /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:2/0:2:2:0/block/sdc /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:3/0:2:3:0/block/sdd /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:4/0:2:4:0/block/sde /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:5/0:2:5:0/block/sdf /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:6/0:2:6:0/block/sdg /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:7/0:2:7:0/block/sdh /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:8/0:2:8:0/block/sdi /devices/pci0000:00/0000:00:02.2/0000:03:00.0/host0/target0:2:9/0:2:9:0/block/sdj 

我可以跟踪他们的RAID卡

 >: lspci | egrep 02.2\|03.00 00:02.2 PCI bridge: Intel Corporation Xeon E5/Core i7 IIO PCI Express Root Port 2c (rev 07) 03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 01) 

但我不能追踪任何进一步的（突袭卡或扩展器上的端口），scsi目标数字是连续的，介意我有四个空插槽，所以我会有预期目标数字“跳过”几个。

• 如何更新GCE实例pipe理服务
• 如何用varnish和nginxconfiguration多个域
• 为多个NICconfigurationiproute2并进行validation
• 在带有BCM57800 NIC（bnx2x）的Debian 7.10服务器上的巨型帧（mtu 9000）
• CentOS极其缓慢的DNS查询

谢谢。
