Greeting,
By default powershell does not populate subattributes. You can get all of the volume info with this command.
$vols = Get-NcVol -Template -Fill
$vols = Get-NcVol
The -fiil attribute forces the complete array to populate.
If you are only targeting a specific Sub attribute you can get it with this command.
$v = Get-NcVol -Template
Initialize-NcObjectProperty $v VolumeStateAttributes
$v = Get-NcVol
if you are trying to determine what is in a varible
$v|gm
Hope this helps
John
