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.
