is it possible to set scsitargetid value from 0 to 1?

Question

is it possible to set scsitargetid value from 0 to 1?

Devon_Springs 1

I have a simple application that need to look for a specific drive that has a value of 1 for scsitargetid.

When I use the command below to get all the scsi information for all of the PHYSICAL drives on my development PC I get the following output.

Get-WmiObject Win32_DiskDrive | select-object DeviceID,{$_.size/1024/1024/1024},scsiport,scsibus,scsitargetid,scsilogicalunit | out-file -FilePath c:\Users\Tester\Desktop\OutputPhysicalDrives.txt

"OutputPhysicalDrives text file output's"

DeviceID : \.\PHYSICALDRIVE1
$_.size/1024/1024/1024 : 931.510956287384
scsiport : 0
scsibus : 1
scsitargetid : 0
scsilogicalunit : 0

DeviceID : \.\PHYSICALDRIVE2
$_.size/1024/1024/1024 : 465.759308338165
scsiport : 0
scsibus : 2
scsitargetid : 0
scsilogicalunit : 0

DeviceID : \.\PHYSICALDRIVE0
$_.size/1024/1024/1024 : 447.129242420197
scsiport : 0
scsibus : 0
scsitargetid : 0
scsilogicalunit : 0

Question is, how would I set PHYSICALDRIVE2's scsitargetid value from 0 to 1 so I can use this to identify PHYSICALDRIVE2 as the drive I want to use on my application.

Hello @PMT the environment that I am trying to configure is not virtualized and not using VMware. I am trying to do this on a physical system.

What bigger problem are you trying to solve?

I want to set PHYSICALDRIVE2's scsitargetid value from 0 to 1, but I want to do this on a non-virtualized environment that does not use Vmware. Overall question is, if this is even possible to do in a non virtualized/VM environment.

Thank You

Restating the original question is not describing the bigger problem you are trying to solve. WHY do you want to change the target id? What depends on the target id being a specific value?

I have an application that runs on a system that has multiple SSD drives that are plugged in at various times.

if I was to plug in 2 identical SSD drives that are in the same scsibus, I would need to differentiate the one that has an scsitargetid value of 1 so then my application can output a message that the SSD drive that has a value of 1 for scsitargetid is not connected to the system.

Let me know if you need me to clarify it more.

You can't change the target id from user mode. If you are using targetid as a way to uniquely identify the disks, there are other ways to do so. You have to change how the code is tracking the disks, you can't force the disks behavior to match the code.
