Connection between VMware SCSI and OS specific path definitions

Hello together,

in connection to our backup we need to find out which disk in the operating system of a VM corresponds to which SCSI Controller ID.

I already searched on the internet for articles and did some tests in our environment but did not really find anything helpful answering this question.

Do you have any kind of overview for that? And is it always the same for every OS or does this definition even vary each time?

In our case for example we need this information for a VM running Windows Server 2012 having several VMDK disks.

Pfad 161 (Bus Number 0, Target Id 0, LUN 0)

Pfad 161 (Bus Number 0, Target Id 1, LUN 0)

Pfad 161 (Bus Number 0, Target Id 2, LUN 0)

Pfad 161 (Bus Number 0, Target Id 3, LUN 0)

Pfad 161 (Bus Number 0, Target Id 4, LUN 0)

Pfad 161 (Bus Number 0, Target Id 5, LUN 0)

Pfad 161 (Bus Number 0, Target Id 6, LUN 0)

Pfad 161 (Bus Number 0, Target Id 8, LUN 0)

Pfad 256 (Bus Number 0, Target Id 2, LUN 0)

Pfad 256 (Bus Number 0, Target Id 3, LUN 0)

Pfad 256 (Bus Number 0, Target Id 4, LUN 0)

Pfad 256 (Bus Number 0, Target Id 5, LUN 0)

Pfad 256 (Bus Number 0, Target Id 6, LUN 0)

Pfad 256 (Bus Number 0, Target Id 8, LUN 0)

Pfad 256 (Bus Number 0, Target Id 9, LUN 0)

Pfad 256 (Bus Number 0, Target Id 10, LUN 0)

Pfad 256 (Bus Number 0, Target Id 11, LUN 0)

Pfad 256 (Bus Number 0, Target Id 12, LUN 0)

Pfad 256 (Bus Number 0, Target Id 13, LUN 0)

Pfad 256 (Bus Number 0, Target Id 14, LUN 0)

Pfad 256 (Bus Number 0, Target Id 15, LUN 0)

"Pfad" is german and probably stands for path in the english OS.

Thanks in advance for your help.

Greetings

Michael
