- VMware vCenter integration with NetApp storage
Issue
- When attempting to add a NetApp storage system (FAS2750 running ONTAP 9.11.1P7) to ONTAP Tools for VMware vSphere (OTV), the following error is displayed:
The certificate is invalid or is missing the 'SubjectAltName'
or
The certificate is invalid or is missing the 'SubjectAltNameIP'
