I understand you are using AIX and attempting to mount your NFS4.1 Azure File share. Azure Files requires NFS4.1 which I don't believe is an option with AIX. I only see NFS4 and NFS3 when looking at the IBM documentation. I recommend reaching out to IBM support to see if they can support NFS4.1. Alternatively, you can consider using NFS for Blob storage or seeing if you can use the SMB protocol.
