Does the EOA of NetApp ONTAPI impact PeerGFS?

Question

NetApp is planning the End of Availability (EOA) of ONTAPI (ZAPI). Does this affect PeerGFS, and if so, does PeerGFS support NetApp's new REST API?

NetApp initially planned for the EOA of ONTAPI to be in January 2023, but this has been postponed indefinitely, as noted in NetApp Product Communique CPC-00410 (CPC-00410 - Deferral of ONTAPI (ZAPI) End-of-Availability Announcement (netapp.com). Even with this delay, ONTAPI might be disabled by default in ONTAP 9.14.1 and later.

Answer

Peer Global File Service (PeerGFS) has traditionally relied upon ONTAPI for interactions with all NetApp platforms. However, PeerGFS v5.2.0 and newer versions support NetApp's new REST API, starting with ONTAP 9.11.1 and above:

If you are running PeerGFS v5.2.0 or later with ONTAP 9.11.1 or newer, you'll need to run the following command from our NetApp ONTAP Prerequisites document via SSH to ONTAP to enable REST API integration:
CODE
```
security login create -vserver <SVM Name> -username <User Name> -application http -authmethod password -role vsadmin
```

If you are running an older version of PeerGFS, cannot upgrade to v5.2 or later, and you are using ONTAP 9.13.1 or earlier, ONTAPI will continue to function properly.
If you are running an older version of PeerGFS and cannot upgrade to v5.2 or later, but have already upgraded to ONTAP 9.14.1 or later, you can reenable ONTAPI by running the following command via an SSH connection to ONTAP:
CODE
```
system services web ontapi modify -suspended false
```
