Get-NaVol : Object reference not set to an instance of an object.

Hi All,

I'm trying to get the list of volumes from the storage system via Get-navol. Its working for some of the systems and not for few, I compared systems with same ONTAP version systems. So i don't think it is due to ONTAP version.However on a Non-Working system , I was able to perform other commands such as Get-NaSystemVersion. Is it something to do with the timeout ?

Below is the error log

Get-NaVol : Object reference not set to an instance of an object.

Can you please enable debug logging through 'Set-NaToolkitConfiguration DEBUG' and then post the output? That will help determine what actually went wrong.

Even with the line $c = Connect-NaController $filer added, I still see only one aggr in the output.

Hi Naman,

Did you mean to post this to the other thread (about getting aggr-space info from multiple volumes)?

In that case, I suggest

printing out $filer to check all filers are indeed being iterated over.
printing the $c to make sure each filer is getting connected to
Remove the export-csv and see if all data is being displayed

Running my script on my own setup does show aggrs from all filers in my 7mode.txt, as you can see in my aggr.csv ... So I can't think of anything else that's going wrong in your setup.

Hi,

I think I found the solution. The command has a standard timeout of 60s. On some controllers this timeout is not sufficient. If you issue $gobal:CurrentNaController.TimeoutMsec=600000 the timeout is increased for the current controller and the command will work.

Stefan

Thank you,

$global:CurrentNaController.TimeoutMsec=600000

fixed my issue also with > Get-NaQuotaReport
