From,when, I execute the script, getting error, SCSI ID field shows blank

You cannot call a method on a null-valued expression.

At C:\VM_RDM_Info.ps1:23 char:29

+                 $ScsiId = &{$strControllerKey = $_.ControllerKey.ToString(); "{0 ...

+                             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException

    + FullyQualifiedErrorId : InvokeMethodOnNull

Cannot index into a null array.

At C:\VM_RDM_Info.ps1:23 char:78

+                 $ScsiId = &{$strControllerKey = $_.ControllerKey.ToString(); "{0 ...

+                                                                              ~~~

    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException

    + FullyQualifiedErrorId : NullArray

Please help.

That line should be

$row.ScsiId = &{$strControllerKey = $dev.ControllerKey.ToString(); "{0}`:{1}" -f $strControllerKey[$strControllerKey.Length - 1], $dev.Unitnumber}

Thanks for your reply,

I am getting output as 00:00 which is not correct for that disk. (correct SCSI ID is 1:0)

Am I missing something ?

Thanks

My mistake, the last part should also say $dev instead of $_.

I corrected it above, try again
