Server rename後HP SMH出現SSL (https) connection have been replaced

Error message:
The certificate and keys used by SMH to establish SSL (https) connection have been replaced. This can happen due to any one the following reasons: the previous version is deleted (accidentally or maliciously), the previous version is replaced by another application (HP SIM replaces the certificate and keys when installed on top of SMH). Take the appropriate action after verifying the status of the previous version.

Solution
rename the file /opt/hp/hpsmh/conf/smhCertDate.txt and restart the service hpsmhd.
