API services returning empty list of clusters

marcinlub — Wed, 04 Jun 2025 13:59:58 GMT

Hello everyone,

I have just installed (with lot of problems on the way 🙂 OnCommand API Services.

I have added a single cluster for tests.

When I try to get the list of clusters with

https://IP:8443/api/5.0/ontap/clusters

I'm getting response with empty list

<apiServerResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="">
<status>
<code>SUCCESS</code>
</status>
<result>
<total_records>0</total_records>
</result>
</apiServerResponse>

however if I try to get

https://IP:8443/api/1.0/admin/storage-systems

I'm getting this single cluster without any issue.

What am I doing wrong?

May be some issue with discovery. Can you do below things and let us know ?

1. re-start api service using below commands

# service apiserver stop

# service apiserver start

2. wait for 5 min to discovery to complete.

3. check is api/5.0/ontap/clusters showing cluster.

4. if not, it may be some problem with MEGA. please share with us logs to degug.

It was a problem with insufficient rights for the user used to connect to the cluster. After logging with a user with admin rights - it works now.
