NetAppSSLCertificateRenew

ONTAP uses self-signed certificates by default for management
of the environment.  These certificates have a typical expiration date of 1 year (365 days).  
This KB describes the process to recreate the certificates:  
https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/How_to_renew_a_Self-Signed_SSL_certificate_in_ONTAP_9

This script handles the steps outlined in the article by doing the following:
   1) Connecting to a cluster
   2) Collecting all existing certificates
   3) Ensuring the certificate is self-signed
   4) Creates a new certificate with the same properties as the previous one with a 10 year expiration
   5) Configures SSL on the SVM to use the new certificate
   6) Deletes the previous self-signed certificate
