Intermittent System.IO.FileNotFoundException from Get-NaHostDisk and Get-NaHyperV

hugh_kelley — Thu, 05 Jun 2025 06:17:59 GMT

I have a script that runs hourly inside our monitoring platform and occasionally (script runs once an hour, condition occurs once every few days) I get this exception

System.IO.FileNotFoundException: The system cannot find the file specified. (Exception from HRESULT: 0x80070002)

from either of these iterations:

foreach($disk in Get-NaHostDisk)

{}

foreach($disk in (Get-NaHyperV $vm.Name).Storage)

{}

It seems to self-resolve the next time the script runs and it happens on multiple servers (all running SMHV). Any ideas why?

Do you have disks adding/removing or moving between servers on a regular basis?

The next time you see that, please run this command and paste the output here:

$Error[0] | fl -force

That'll give us a stack trace with more info to debug. Thanks!

It took a few weeks for the condition to return, but as requested:

I frequently get the exact same error when running Get-NaHostDisk. Running a second time generally works. But this delays things significantly.

Here is the stack trace I get:

And here is some Powershell I have written to get past the issue for the time being.

$retries = 3
$success = $false 
while ((-not $success) -and ($retries -gt 0))
{
    $retries -= 1
    "Attempting to run [Get-NaHostDisk -DataOntap].  $retries retries remaining."
    try
    {
        $NaHostDisks = Get-NaHostDisk -DataOntap
        $success = $true
    }
    catch
    {
        "ERROR::$($_.Exception.ToString())`nWhile executing Get-NaHostDisk."
    }
}
  
if (-not $success)
{
    throw "Unable to get the HostDisk mapping from the NetApp."
}

A better solution to this would be appreciated.
