Hi,
Both api work identicaly, these values are only filled if you set value with
>vserver modify -vserver <vserver> -aggr-list <aggr1>, <aggr2>
By default all aggregates are available by all vserver when -aggr-list is emply (-)
If you want list off aggregates just use
<?xml version="1.0" encoding="UTF-8"?>
<netapp xmlns="http://www.netapp.com/filer/admin" version="1.31">
<aggr-get-iter>
<desired-attributes>
<aggr-attributes>
<aggregate-name></aggregate-name>
</aggr-attributes>
</desired-attributes>
</aggr-get-iter>
</netapp>
