Test-Rdma.ps1 does not work with Windows 2025 #623
Description
It looks like they changed the performance counter names in Windows 2025 (maybe earlier versions as well). This causes the RDMA test to fail with the following:
ERROR: RDMA traffic test FAILED: Please check
ERROR: a) physical switch port configuration for Priorty Flow Control.
ERROR: b) job owner has write permission at 192.168.100.3 \C$
If you remove the ignore you see:
Get-Counter : The specified object was not found on the computer.
At line:1 char:1
+ Get-Counter -Counter "\SMB Direct Connection(_Total)\Bytes RDMA Writt ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidResult: (:) [Get-Counter], Exception

$written and $sent will be empty due to this.
Adding this code fixes the issue.
Replace lines 291 and 292 with:
$osVersion = (Get-CimInstance Win32_OperatingSystem).Version
if ($osVersion -like "10.0.26*") {
$written = Get-Counter -Counter "\SMB Direct\Bytes RDMA Written/sec" -ErrorAction Ignore
$sent = Get-Counter -Counter "\SMB Direct\Bytes Sent/sec" -ErrorAction Ignore
} else {
$written = Get-Counter -Counter "\SMB Direct Connection(_Total)\Bytes RDMA Written/sec" -ErrorAction Ignore
$sent = Get-Counter -Counter "\SMB Direct Connection(_Total)\Bytes Sent/sec" -ErrorAction Ignore
}
