SDK - Get Non-Root Aggregates

Hi,

I have used the ZAPI tool to generate the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<netapp  xmlns="http://www.netapp.com/filer/admin" version="1.31">
  <aggr-get-iter>
    <desired-attributes>...snipped for brevity...</desired-attributes>
	<query>
		<aggr-attributes>
			<aggr-raid-attributes>
				<is-root-aggregate>false</is-root-aggregate>
			</aggr-raid-attributes>
		</aggr-attributes>
	</query>
    </aggr-get-iter>
</netapp>

Unfortunately, this still returns root aggregates (running against a CDOT 8.3.2P9 cluster). How can I get only non-root aggregates?

Thanks!

Not familiar with the API.. but have you tried looking for "ha_policy" of "cfo"? Only root aggregates have the ha_policy set to "cfo" (controller failover) - all others are sfo (storage failover).

Maybe check for aggr-raid-attributes -> has-local-root and aggr-raid-attributes -> has-partner-root to both be false. FWIW, your query works fine against my ONTAP 9.0 system.

Thanks for your suggestions, everyone.

Looks like it's actually an issue with the ZAPI tool - I can use the tool to generate the code, but if I try to execute it, it brings back the wrong results. If I copy the generated XML and run it outside of the tool, it works as expected.
