When a storage system is communicating with an external device, you are advised to use the certificate verification mode to improve service security. It is recommended that you replace the default security certificate with a certificate applied from an official authority and replace the certificate that is about to expire in a timely manner. This operation enables you to import and activate a certificate.
After you import and activate a certificate in one scenario, choose Monitor > Alarms and Events > Events. Wait until certificate import success, certificate activation success, and certificate update success events are displayed in sequence, and then import and activate the certificate in the next scenario.
