Mapping a VMWARE SCSI device to its Linux OS device

In VMWARE, you can see your SCSI channel and ID number in the Virtual Machine's Properties window under "Hardware": 



Once you have this information, you can then start determining where it is being used by your system either as /dev/ or an LVM physical volume.

Check the attached SCSI devices on linux:

[root@<server> ~]# cat /proc/scsi/scsi
Attached devices:
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: NECVMWar Model: VMware IDE CDR10 Rev: 1.00
  Type:   CD-ROM                           ANSI  SCSI revision: 05
Host: scsi2 Channel: 00 Id: 00 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0
  Type:   Direct-Access                    ANSI  SCSI revision: 02
Host: scsi2 Channel: 00 Id: 01 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0
  Type:   Direct-Access                    ANSI  SCSI revision: 02
Host: scsi2 Channel: 00 Id: 02 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0
  Type:   Direct-Access                    ANSI  SCSI revision: 02
Host: scsi2 Channel: 00 Id: 03 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0
  Type:   Direct-Access                    ANSI  SCSI revision: 02

And finally you can co-relate that with the OS's own mapping:

[root@<server> ~]# ll /sys/bus/scsi/drivers/sd/2\:0\:3\:0/block/
total 0
drwxr-xr-x. 8 root root 0 Nov 19 15:10 sdd

This means that the SCSI device on Channel 00 ID 03 maps to /dev/sdd
